Move a large part of SYS.h defines to DEFS.h to match where other platforms
put their macros, and also turn a few "EXIT" into "END" for consistency with
other platforms. NFCI

Make sure the syscall table entries are aligned on a 4-byte boundary.
Required for strict-alignment architectures and a good idea on others.

In libc a few syscall# entries (break, sigprocmask, _tfork, _threxit)
are duplicated because additional or inline uses occur (that situation
is handled elsewhere)

Use a Thread Information Block in both single and multi-threaded programs.
This stores errno, the cancelation flags, and related bits for each thread
and is allocated by ld.so or libc.a. This is an ABI break from 5.9-stable!

Make libpthread dlopen'able by moving the cancelation wrappers into libc
and doing locking and fork/errno handling via callbacks that libpthread
registers when it first initializes. 'errno' *must* be declared via
<errno.h> now!

Clean up libpthread's symbol exports like libc.

On powerpc, offset the TIB/TCB/TLS data from the register per the ELF spec.

Make pthread_atfork() track the DSO that called it like atexit() does,
unregistering callbacks if the DSO is unloaded. Move the callback
handling from libpthread to libc, though libpthread still overrides the
inner call to handle locking and thread-library reinitialization.
Major version bump for both libc and libpthread.

System call stubs don't have a frame of their own, so use EMTRY_LEAF instead
of ENTRY. This avoids emitting bogus unwind entries, which makes gdb a lot
happier.

Add PSEUDO_NOERROR similar to that used by NetBSD.
Some ports were setting errno in PSEUDO and some were not. Now errno
is set for all in PSEUDO and PSEUDO_NOERROR is provided for the
non-errno case (only used by _exit).

Needs testing on vax and m88k.
XXX - hppa and powerpc still lack a real PSEUDO_NOERROR implementation.
Currently PSEUDO_NOERROR and PSEUDO are the same (so builds don't
break on those platforms).
