Syscall Separation Part 10 for Review

Remove the FreeBSD 3.x signal code.  This includes osendsig(),
osigreturn() and a couple of structures that these syscalls depended

Split the sigaction(), sigprocmask(), sigpending(), sigsuspend(),
sigaltstack() and kill() syscalls.

Move the 4.3BSD signal syscalls osigvec(), osigblock(), osigsetmask(),
osigstack() and okillpg() to the 43bsd subtree.  I'm not too sure
if these will even work with the FreeBSD-4 signal trampoline code,
but they do compile and link.

Implement linux_signal(), linux_rt_sigaction(), linux_sigprocmask(),
linux_rt_sigprocmask(), linux_sigpending(), linux_kill(),
linux_sigaction(), linux_sigsuspend(), linux_rt_sigsuspend(),
linux_pause() and linux_sigaltstack() with the new in-kernel syscalls.
This patch kills 7 stackgap allocations in the Linuxolator.

Also, I haven't yet touched the PC98 sources.  I'll probably try cleaning
them up this weekend.
