1fffdfb680 Header consolidation - main.h, misc.h, and share.h merge to advent.h. 
For a project this small size with a small type ontology, it's better
C style to have one header where all the assumptions about types and
structures are immediately visible.

This is a first step towards turning all that global state into a handful
of structures - probably just two, one saveable as a binary game state.

39b2c286d9 Fix a bug in RNDVOC() that prevented the reservoir magic word for working. 
To do this, I first had to refactor the code into proper C, just so I could understand it. Then I found another layer of encryption around the value itself. Finally, I discovered that the line to actually set the new magic word was placed such that it was using a global index instead of the local one.

e281f895d4 Factor out handling of variables populated from the database. 
This reorganization is a first step toward handling database compilation separately.

341bf61139 Once again, take srand()/random() out of the initialization chain. 
They have exactly the wrong kind of randomness for this job - not
returning consistent sequences across different platforms or C library
versions, and because pseodorandom not really better than sampling
the clock.

06795f691f Revert SEED handling and comment orocessing. It broke database compilation. 
This code is remarkably like the game it implements - a maze of twisty
little FORTRANisms, all alike.  Very easy to get lost.

91bfd55c1c Begin gathering saveable game state into a structure. Not yet complete. 
No logic changes.  A bunch of globals turn into fields (with the same names
except for lowercasing) in struct game_t.

Eventually this will allow drastic simplification of the save/load logic.

ec4c0c8cd0 Input source is parametrized all the way down. 
This means that, potentially, do_command() could be called on any text file
pointer and the right thing would happen.

42e6e7cdb7 Fix strange inside-out organization of the input routines. 
Seems to have nbben a result of FORTRAN not having anything like a
stream object that can be passed around.

A step towards logging and log replay.

301f38586b Fix up case on all comments to make them more readable. No code changes. 
The all-capsing was a FORTRAN remnant.Also, we change a few FORTRANisms
so they are less confusing in this C context; ".TRUE." and ".FALSE." become
"true" and "false", "MOD" is mapped to % in places tha t are like C expressions
and (usually) "modulo" in places that aren't.

6ef3e68c0c Replace fDATIME with ANSI/POSIX clock_gettime(). Rip out DOS/AMIGA shims. 
The thinking here is that we simplify life by going pure ANSI/POSIX.
This is a text game.  If it ever runs on anything but Unix again it's
almost certain to be on something like WSL that supplies a
POSIX-conformant text console.
