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.

/*
**  CAUSE A NOVA TO OCCUR
**
**	A nova occurs.  It is the result of having a star hit with
**	a photon torpedo.  There are several things which may happen.
**	The star may not be affected.  It may go nova.  It may turn
**	into a black hole.  Any (yummy) it may go supernova.
**
**	Stars that go nova cause stars which surround them to undergo
**	the same probabilistic process.  Klingons next to them are
**	destroyed.  And if the starship is next to it, it gets zapped.
**	If the zap is too much, it gets destroyed.
