4fb740b8de Implement pthread_atfork() (in libc, because the required threadlib 
stub behavior is exactly the same as the usual behavior).

326194c69f Update stack frame allocation for XMM state having been added to 
mcontext_t; spotted by Frank van der Linden.
While here, also align the on-stack ucontext as required.

c061e6bf8b Enable the libc-provided signal trampoline. The old __sigaction14 
entry point has been replaced by the new __sigaction14() which is a
wrapper around the __sigaction_sigtramp system call (which is itself
not directly exposed outside of libc).

No shared library version change is necessary; no new symbols
are exposed outside of libc.

8aa4d3caec New __sigaction14() system call stub which registers the signal 
trampoline, and the signal trampolines themselves.

NOTE: These are not yet enabled; they will be enabled after further
testing on more architectures.

763eb5645a memcpy/memmove/bcopy: Add diagnostic code to check pointer wraparound. 
The code is enabled only when _DIAGNOSTIC is defined.

92d8b1e9fa Revert previous: .S files are currently compiled with -traditional-cpp, 
so __STDC__ is _not_ always defined.

2d8577fb83 Clean up some rampant code duplication wrt ieee number handling: 
- Add alignment-safe double and float unions.
 - Use the above for the __infinity and __nan constants on all
   architectures that use the standard ieee754 representation of
   those constants.
 - Add a single copy of various ieee754 math functions (frexp, isinf,
   isnan, ldexp and modf) that had numerous duplicates among the
   arch-specific directories.
 - Use the above functions on all architectures where the generic C
   versions where used.  Architectures that had local assembly
   routines are untouched (for those functions only).

ac8c1c29e9 * Add WSYSCALL() to SYS.h, which creates a system call with an 
internal name and a weak alias for the name.
* Add a WEAKASM syscall list, and process it.
* Make sysarch() have an internal name (_sysarch()).

b25c2304f3 I have no idea why this syscall wrapper does some very un-unix-like 
argument prefrobbing, in particular, it computes max(addr, __minbrk)
and uses that. The code is like this even in the ancient libc/i386 tree,
back to the earliest rev 1.2. I did not see it Lite 1, but I'm not totally
sure what the random site I found was serving up.
*
* However, I do know that it should use jb and not jl.

there.
