Complete initial import from mySQL 3.22.4 (mit-pthreads/).

Lots of dross to move and remove yet.

At minimum:
o	remove GNU config and GNU Makefiles
o	build arch directory and migrate away machdep/
o	rebuild BSD Makefiles
o	move notes etc. into doc/

+
+93.03.26

+  in fd.c (Already done in fd_sys.c)
+
+1. Added a declaration of &#34;signal&#34; to include/signal.h
+2. Modified PANIC macro to operate like assert and call a new function
+   panic_kernel.  Added new file pthreads/panic.c.
+3. Added support for fstatfs syscall for linux (mod to
+   syscall-i386-linux-1.0.S).
+4. Added missing function declarations to machdep/linux-1.0/socket.h:
+   getsockopt
+   setsockopt

+   getpeername
+   send
+   recv

+   _proto_buf.
+8. Fix bug in res_internal.c where buffer pointer was improperly 
+   maintained.
+9. Fix return value handling for POSIX function implementations.
+10. Fix bug in select handling where a thread could be incorrectly 
+    resumed with no sockets ready.  Also added proper handling of
+    selecting for exceptions (this was not implemented at all).
+11. Added deadlock detection to pthread_join (it can now return an
+    EDEADLK error).
+12. Added support for pthread_cancel, changes to lots of files for this.
+13. Add new function __pthread_is_valid that searches the pthread list
+    for a specified pthread_t value.
