Don't include <sys/types.h> or "exit.h"; no longer needed.

(errno): Remove decl; we now assume C89 or better.
Include unistd.h if available, for gethostname.
(ENAMETOOLONG): Define to 0, not 9999, to avoid colliding with
existing errno values if any.
(gethostname): Remove decl, since unistd.h declares it (or doesn't,
in which case it's an older system and it should just work).
(xgethostname): Don't assume host name length is less than INT_MAX.
Exit if malloc fails, just as the comment says.
