3160112ece Accessibility: Show a message when monster is spotted
Adds a new boolean option, spot_monsters.  If on, every time
the hero notices a monster which was out of sight before,
a message is given.  Combine with accessiblemsg to get the
monster location:

(3north): You see a newt.

Breaks saves and bones.

e4026d55fb Lazy evaluation of overview info
Callgrind showed recalc_mapseen was three times more expensive (in terms
of instructions read) than anything else in our codebase.  It was being
called in every vision change, re-evaluating the last seen map terrain
type for every map location in sight.

Remove updating the lastseen info in the vision code, and make a small
change so newsym() uses update_lastseentyp.

From my short tests, this seems to work correctly ...

caa8aa7f60 reinstate obj guard on _see_with_infrared macro
Checking the callers:
newsym() the use of see_with_infrared() is guarded by
    } else if ((mon = m_at(x, y)) != 0 [...]

do_mgivenname() the use of see_with_infrared is guarded by !mtmp:
        && (!mtmp
            || (!sensemon(mtmp)
                && (!(cansee(cx, cy) || see_with_infrared(mtmp))

howmonseen(mon) dereferences mon in other places, so it would
    segfault if mon were NULL; howmonseen has NONNULLARG1.

f61cfe7e48 pacify static analyzer - vision.c
Include some assertions to convince the analyzer that some pointers
can't be Null.  They're Null if 'vis_func' is non-Null but only used
when that function pointer is Null and they have values.

If there's a macro that's defined when the analyzer is running and
undefined when not--or vice versa--it could be used to control NDEBUG
and avoid the assertion code when not analyzing.  That's a bit like
using fake code to pacify 'lint'; however, since the assertions should
never fail, suppressing them isn't really switching to fake code.

I reordered a couple of macros so that the set of them matches the
comment which precedes them and refers to "the last three".  It is
referring to the three within the block comment rather than the macro
defintions but putting those in the same order removes any ambiguity.

02a48aa8cf split g into multiple structures
The consolidation of global variables from scattered source
files into decl.c and declared in decl.h was begun in 3.7.0.
Their placement in common files was done for centralized
initialization and potential re-initialization during a
"play again" scenario.

It wasn't really necessary for all of them to be housed in a
single huge structure to meet the "play again" requirement,
and the single huge structure has been a little unwieldy when
it comes to maintenance.

Following this commit, instead of one single extremely large structure
named 'g' to house all of the relocated global variables, they
are distributed into several ga through gz.

To make things easy for the developer, each variable is placed
into the struct corresponding to the starting letter of the variable.
That way, no lookup is required in order to know which struct houses
a particular variable, it is a simple match to the starting letter
for all the centralized global variables.

A global variable named 'amulets', would be found in ga.
    ga.amulets
     ^ ^
A global varable named 'move', would be found in gm.
    gm.moves
     ^ ^
A global variable named 'val_for_n_or_more' would be found in gv.
    gv.val_for_n_or_more
     ^ ^
A global variable named 'youmonst' would be found in gy.
    gy.youmonst
     ^ ^

619781dbb8 Add 'mdistu' macro
Short for distu(mtmp->mx, mtmp->my) (i.e. the distance between the hero
and the specified monster), which is a very common use of distu().  The
idea is that this would be a convenient shorthand for it; I actually
thought it (or something very similar) existed already, but couldn't
find it when I tried to use it earlier.  Based on the number of uses of
fully-spelled-out 'distu(mtmp->mx, mtmp->my)' replaced in this commit
I'm guessing I just imagined it.

b37f922cf7 viz_array[][] type
viz_array[][] is indexed by coordinates but the data it contains has
nothing to do with them so it shouldn't have been changed to coordxy.
'char' was sufficient; 'uchar' would have been better; this invents
'seenV' instead.  This led to a cascade of required changes.  The
result is warning free and seems to be working but my fingers are
crosssed....

30b557f7d5 change xchar to other typedefs
One of the drivers of this change was that screen coordinates require a
type that can hold values greater than 127. Parameters to the window
port routines require a large type in order to be able to have values
a fair bit larger than COLNO and ROWNO passed to them, particularly for
their use to the right of the map window.

This splits the uses of xchar into 3 different situations, and adjusts
their type and size:

                        xchar
                          |
               -----------------------
               |          |          |
            coordxy     xint16     xint8

coordxy: Actual x or y coordinates for various things (moved to 16-bits).

xint16:  Same data size as coordxy, but for non-coordinate use (16-bits).

xint8:   There are only a few use cases initially, where it was very
         plain to see that the variable could remain as 8-bits, rather
         than be bumped to 16-bits.  There are probably more such cases
         that could be changed after additional review.

Note: This first changed all xchar variables to coordxy. Some were
reviewed and got changed to xint16 or xint8 when it became apparent that
their usage was not for coordinates.

5d56da3d32 bubble/cloud save/restore overhaul
The air bubbles on the Plane of Water and the clouds on the Plane of
Air were being saved and restored as part of the current level's state
(which is the 'u' struct and invent and such) rather than with the
current level itself.  That was ok for normal play, but for wizard
mode's ^V allowing you to return to a previously visited endgame level
after moving to a different one it meant a new set of bubbles for
Water and new set of clouds for Air.  Even that was ok since it only
applied to wizard mode, but using #wizmakemap to recreate Water or Air
while you were on it added a new set of bubbles or clouds to the
existing ones.  If repeated, eventually there wouldn't be much water
or air left.

Instead of just adding a hack to #wizmakemap, change save/restore to
keep the bubbles/clouds with the level rather than with the state.
That wasn't trivial and now I know why the old odd arrangement was
chosen.  Saving hides u.uz by zeroing it out for levels that the hero
isn't on and it is zero during restore so simple checks for whether a
given level is water or air won't work.

This also adds another non-file/non-debugpline() use of DEBUGFILES:
 DEBUGFILES=seethru nethack -D
will make water and clouds be transparent instead of opaque.  It also
makes fumaroles and other light-blocking gas clouds be transparent
which wasn't really intended, but avoiding it would be extra work that
doesn't accomplish much.

Increments EDITLEVEL for the third time this week....

6ae05df1c3 more reformatting - label placement
Indent all labels one space.  Having uniform placement makes spotting
them much easier.  (Having no indent at all would impact the change
bars of 'git diff'.  Those display the last unindented line--which
doesn't start with punctuation--occuring before each band of changes,
so usually the name of the function being changed now that we no
longer have unindented K&R-style function argument declarations.)

While in there, shorten or split various wide lines and replace a few
tabs with spaces.

59818fb6ab implement #986 - camera flash 'tweak'
Implement the suggested feature that a camera's flash actually update
hero's memory of the map as it traverses across the level.  Turned
out to be more work than anticipated despite having the code for a
thrown or kicked lit candle or lamp to build upon.

Among other things it needed to update the circle code to handle
previously unused radius 0 to operate on the center point only.  I've
never touched that before and hope this hasn't introduced any bugs.

Also removes several instances of vision code operating on column #0.
(At least one is still present.)

27fe555bc1 src/ formatting
Clean up quite a bit of minor things found with simple grep patterns:
operator at end of continued line instead of beginning of continuation
(and a few comments which produced false matches, so that they won't
do so next time), trailing spaces (only one or two of those), tabs (a
dozen or so of those), several casts which didn't have a space between
the type and the expression (I wasn't systematic about finding these).

I think the only code change was in the function for the help command.

e2eba2ae9a endgame portal detection (trunk only)
In the newsgroup about three weeks ago someone described trying to
use the Bell of Opening to find the magic portal on the Plane of Water
and not succeeding.  It's supposed to work like a wand of secret door
detection to mark nearby traps as known.  And does, but it turns out
that the wand wasn't working as expected there either.  They both require
line of sight, and since the water outside of the bubbles blocks that
they only found the portal if it was within the same bubble as the hero.
(Clouds on the Plane of Air posed a similar problem, although monster
activity usually reveals the portal on that level so this wasn't much of
an issue there.)  Since the detection magic doesn't require the hero to
see the traps--wand and Bell both work while blind--this patch overrides
the line of sight requirement on the Planes of Water and Air.  As long as
hero is within the detection magic's range, the portals on those levels
will get marked as having been seen and when the hero gets into the right
bubble or out of the clouds the portal traps will be shown on the map.

     The line-of-sight override code is simple-minded and lets players
find traps through boulders when/if those are present (but the found
traps won't be seen yet since vision still controls the map display).
Also, it assumes that only water/air/cloud terrain is present so could
potentially yield strange results if any other terrain gets introduced on
either of those two levels.

Dungeon Map Overview Patch for Nethack 3.4.3
Version 3
=============================================================================
Changelist:
    v3: Changed #level to #annotate to avoid #levelchange collision.  Fixed
        handling of elemental planes and astral plane (oops).  Changed
	formatting to be slightly closer to print_dungeon()'s.  Should be
	"final" version for 3.4.3.
    v2: Added tracking of trees.  Changed ctrl-m command to ctrl-o.  Portals
        displayed as "sealed" instead of "closed".
    v1: First release.
    (Note: all versions are mutually save compatible.)
=============================================================================
This patch creates a dungeon map overview that is recorded as the player
explores the dungeon.  I was tired of returning to a game a few days later
and having no idea what the dungeon looked like.  Trying to name pieces
of armor with shorthand didn't work so well as an intermediate solution
either, especially around nymphs.

It can be assumed that this map is in the mind of the hero and thus
can't be stolen, can be read when blind, or when buried, or when the hero
doesn't have any hands, or eyes, or hands free, or...etc. On the other hand,
this implies that the hero doesn't remember all of the details ("a fountain",
"some fountains", "many fountains") and that the map is subject to amnesia
when applicable.

This overview tracks fountains, altars, stores, temples, sinks, thrones,
trees, and dungeon branches.  It attempts to not spoil the player nor
reveal more information than the hero knows.  For this reason, it only
tracks dungeon features found in the guidebook and dungeon branches.

This patch breaks save file compatibility.  Sorry.

Added commands
=============================================================================
#overview (ctrl-o, if not in wizard mode) - displays overview
#annotate (ctrl-n, if using numpad) - names current level

Example Output From #overview
=============================================================================
The Dungeons of Doom: levels 1 to level 15
   Level 1:
      A fountain
   Level 3: (My stash.)
      An altar, some fountains
      Stairs down to The Gnomish Mines
   Level 7:
      Many fountains
   Level 8:
      Stairs up to Sokoban, level 7
   Level 15:
      A general store
      Sealed portal to The Quest
The Gnomish Mines: levels 4 to level 7
   Level 7: <- You are here
      Many stores, some fountains, a temple

More Details
=============================================================================
The overview shows only levels that have anything interesting to display and
doesn't show branches that don't have any interesting levels.

To avoid the map revealing more information than the hero knows, the overview
only displays things that the hero has seen or touched.  (If the hero
blinds herself, levitates above a known fountain, and obliterates it with a
wand of digging, the overview will still say that there is a fountain.)

This is done, sadly, by adding 6 bits to the rm struct to track the last
known dungeon type.  On the other hand, this change could potentially allow
a window port to do something like drawing an item and a fountain on the same
square.

Things That Could Be Better And Maybe Some Feedback Would Help
=============================================================================
"<- You Are Here" is pretty goofy
    -...but an indicator of some sort is nice.
=============================================================================
Many thanks to all the kind folks on r.g.r.n. who had very good feedback
about this patch, in particular L (for the trees), <Someone> Papaganou (for the
#annotate suggestion and some formatting feedback), and <Someone> (for the suggestion
of just overriding ctrl-o instead of using the very broken ctrl-m.)
