<email deleted> reported that having a spellcasting monster
destroy some armor while you're in the midst of using 'A' to take that
armor off would result in a crash. The problem was actually more
widespread than that: having a nymph steal worn items (accessories as
well as armor), or a succubus remove them, or being interrupted by monster
activity and then reading a scroll of destroy armor prior to resuming 'A'
could all produce a similar crash. 'A' relied on stale context and could
attempt to manipulate an equipment slot which had become empty, ultimately
leading to an attempt to dereference a null pointer.
The 'R' command didn't have this problem since any accessory gets
removed immediately. The 'T' command already had handling for this:
there's only one item to deal with and multi-turn take off only applies
to some of the slots; the donning() check followed by cancel_don() took
care of those. Only 'A' was vulnerable to the problem and it wouldn't
necessarily need to be interrupted and resumed; loss of the current
multi-turn item or any pending item would be enough--but I'm not sure
whether such item loss could occur without also interrupting the current
activity, so resumption of previous 'A' was probably a requirement for
triggering the crash.
This makes shield and shirt handling be similar to other types of
armor instead of relying on the fact that none of them need to have any
attribute adjustments when put on or taken off. However, there are
still assumptions (the `cancelled_don' stuff) that some slots don't have
any eligible items requiring more than a single turn to use; that should
probably be changed.

This patch:
- collects all context/tracking related fields from flags
into a new structure called "context."
It also adds the following to the new structure:
- stethoscope turn support
- victual support
- tin support
This patch introduces a change to yname() and Yname2() that avoids the
possessive "your" for the hero's normal, fully identified artifacts.
Quest artifacts still get the possessive, as do all other objects and all
objects not in the hero's possession. shk_your()/Shk_Your() are used in
many places with a specific, generalized name for the object, so I didn't
introduce the artifact behavior there, although I did change them to append
a space, which simplified some other code. Through added use of yname(),
there may be some places that used to just say "corpse" that will now be more
descriptive via yname()'s use of cxname(). I'm sure <Someone> will point
out any such places that are too onerous, although nothing obviously is.
I took the opportunity to inspect many uses of "your" and even Your(). Two
new functions are also introduced, yobjnam() and Yobjnam2(), which work
like aobjnam() and yname() combined, because I found that many uses of
aobjnam() were preceeded by "your" and I couldn't generally provide the
desired behavior for artifacts (or future artifacts) without a combined
function. In some cases, this change allowed better sharing of code.
rust_dmg() still takes a string as input which is sometimes initialized
from xname() and often prepends "your" to it. Currently, this isn't a
problem since there currently are no normal, armor artifacts. If/when any
are introduced, rust_dmg() will need to be addressed.
The patch is for the trunk only. A lot of research was required and I
didn't feel the upside was there for repeating it in the 3.4.3 branch.

[confirmed: moveloop -> deferred_goto -> goto_level ->
losedogs -> mon_arrive -> rloc -> impossible]
This patch:
- causes rloc() to return TRUE if successful,
or FALSE if it wasn't.
- adds code to mon_arrive() in dog.c to deal with
the failed rloc()
- allows the x,y parameters to mkcorpstat() to
be 0,0 in order to trigger random placement of the
corpse on the level
- if you define DEBUG_MIGRATING_MONS when you build cmd.c
then you'll have a debug-mode command #migratemons to
store the number of random monsters that you specify
on the migrating monsters chain.
<Someone> reported the messages "It seduces you and you take off your
robe. She stole a burnt +0 robe." I noticed the 2 cases here only dealt
with blindness, not seeing the nymph in general. Also, one case forced
"She", the other "It". Now they both say "She", which is consistent with
the preposition in the 2nd message. We'll continue to the assume the
gender of the seducer is obvious, even when unseen.
Provide more control over message handling for monsters' use
of equipment. This fixes the statue revival problem (inappropriate
feedback when monster puts on speed boots) mentioned in the earlier
"intrinsics of dead monsters" patch.
Monster traits that are used to revive some corpses or statues
with their old attributes were retaining intrinsics conferred by worn
items. To prevent that, strip such attributes at time of a monster's
death before the traits are recorded. Statue handling needs to some
more work; now that extra speed is lost, there's an out of place
message if/when a revived statue gets to put on its old speed boots.

This is a compromise. This doesn't allow vengeance when you were
told "you gladly hand over ...", but does for most other cases, and for
leprechauns.
There was at least one more special case aside from throwing
(jetisoning items to reduce weight after falling in water) which
have needed the same extra code. This is a more general fix.
- new cxname() to simplify doing the right thing in increasingly common cases
- use for bullwhip snagging
- in shopkeeper offer code
- in a couple other existing places rather than duplicating CORPSE checks
- use singular(...) in "swings" cases, since only one can hit. Singular uses
corpse_xname automatically when appropriate
