nhmall 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
     ^ ^

* make it exactly the same as AD&D, adding some more weapons in the process.
* This has the advantage that it is at least possible that the player would
* already know the damage of at least some of the weapons. This was circa
* 1987 and I used the table from Unearthed Arcana until I got tired of typing
* them in (leading to something of an imbalance towards weapons early in
* alphabetical order). The data structure still doesn't include fields that
* fully allow the appropriate damage to be described (there's no way to say
* 3d6 or 1d6+1) so we add on the extra damage in dmgval() if the weapon
* doesn't do an exact die of damage.
*
* Of course new weapons were added later in the development of Nethack. No
* AD&D consistency was kept, but most of these don't exist in AD&D anyway.
*
* Second edition AD&D came out a few years later; luckily it used the same
* table. As of this writing (1999), third edition is in progress but not
* released. Let's see if the weapon table stays the same. --KAA
* October 2000: It didn't. Oh, well.
