d402e09411 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.

71fcc814f8 Launder seed generation through rand() to ensure seed diversity. 
This doesn't affect reproducibility because a) the seed value written to logs is the output of this process, and b) the argument to the seed command *doesn't* get laundered.

df46df6979 Factor out handling of variables populated from the database. 
This reorganization is a first step toward handling database compilation separately.

f9eca41f3a Ensure the ZZZZ magic word is reproducible. 
This happens by making the SEED command also regenerate the magic word.

6ba9a7de7f 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.

31837249f8 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.

484ca4e9fd Revert structurization changes, they broke database compilation... 
...bug showing only if adventure.data was absent.  We'll need to sneak up
on this more carefully.

42189d79d7 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.

dc9d9e467b 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.

040f19adde 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.

18767d52dd 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.
