WARNS6 cleanup (1803 warnings).

ANSI function declarations.

Staticize functions.

Rename local variables that shadow globals.

Use string functions from libc instead of creating our own.

Remove void casts for unchecked function returns.

Spell parameter correctly.

Don't try to return a value from void functions.

Remove compat library requirement (gtty -> ioctl).

Add new function "dowarp" that calls warp() from play.c.  (Taken from
NetBSD).

Change chars that are used for numeric values to shorts so they can be
properly used as array indexes.

/*
**  Check for Condition After a Move
**
**	Various ship conditions are checked.  First we check
**	to see if we have already lost the game, due to running
**	out of life support reserves, running out of energy,
**	or running out of crew members.  The check for running
**	out of time is in events().
**
**	If we are in automatic override mode (Etc.nkling < 0), we
**	don't want to do anything else, lest we call autover
**	recursively.
**
**	In the normal case, if there is a supernova, we call
**	autover() to help us escape.  If after calling autover()
**	we are still in the grips of a supernova, we get burnt
**	up.
**
**	If there are no Klingons in this quadrant, we nullify any
**	distress calls which might exist.
**
**	We then set the condition code, based on the energy level
**	and battle conditions.
