Migrate to POSIX signals. (#190)

Browse Source 
This removes SYSVSIGNALS as we're always and only using POSIX
signals now.

Some platform differences have been papered over. We used to
only ignore SIGPIPE when using BSD signals, but we now ignore
it all the time.

While the SIGFPE code will now compile, it hasn't been updated
to work on modern OSes fully yet as it will need to enable
the correct FP exceptions.

_________ ________________________________________________________
BYTESWAP Used when compiling for a hardware architecture that has
byte-swapped words and word-swapped 32-bit cells, e.g. 80386.
SYSVSIGNALS True when compiling on a system that requires the use of
SYSV (rather than BSD) signal-handling code.
I386 True if compiling for the Sun386i (not just any 80386);
used because the 386i's display controller is odd.
OS4 True if compiling for SunOS 4.x
