c3bb0dae75 Quiet down database compilation. Observe RNG stability. 
At this commit, we can tell that the seeded-RNG nehavopr of this 430
branch is identical to that of master because the axebear log - which
includes randomization of dwarf spawning and the reservoir word -
yields the same results in both versions.

c41dd35268 Ensure the ZZZZ magic word is reproducible. 
This happens by making the SEED command also regenerate the magic word.

2fdd509f32 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.

a416d78a58 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.

12f909bcc9 Start advent430 branch for correctness testing. 
The purpose of this branch is to create a version of the game from
before the bug fixes, refactoring, and logic changes.  We want this so
we can run it against our 100% coverage test suite and see all changes
in behavior.

This branch is forked from the point where the prompt and the oldstyle
option were added.  At this point there had been only two logic
changes:

1. Do initialization of the LCG with gettimeofday(). Note that
this change will not affectt regression testing, since the
initialization done in this way will nbe overridden in the
logs by seed commands.

2. Refactor the input routines to a normal Unixy organization.
This is required for the -l option to work.

This commit just builds the binary at advent430 where it
won't collide with the production version.

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.

23f2dbe814 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.
