84088310ce Handle AVX saving on x86-64 in interrupted smbol lookups. 
If a signal arrived during a symbol lookup and the signal handler also
required a symbol lookup, the end of the lookup in the signal handler reset
the flag whether restoring AVX/SSE registers is needed.  Resetting means
in this case that the tail part of the outer lookup code will try to
restore the registers and this can fail miserably.  We now restore to the
previous value which makes nesting calls possible.

421665c40a Optimize x86-64 syscall cancellation handling. 
The syscall wrappers had to save and restore the syscall parameter
values and return value when calling the functions to enable/disable
cancellation were called.  Not anymore.  The called functions are
special and don't modify any unexpected registers.

b48a267b8f Preserve SSE registers in runtime relocations on x86-64. 
SSE registers are used for passing parameters and must be preserved
in runtime relocations.  This is inside ld.so enforced through the
tests in tst-xmmymm.sh.  But the malloc routines used after startup
come from libc.so and can be arbitrarily complex.  It's overkill
to save the SSE registers all the time because of that.  These calls
are rare.  Instead we save them on demand.  The new infrastructure
put in place in this patch makes this possible and efficient.

515a8908ce Make x86-64 pthread_cond_timedwait more robust. 
It just happens that __pthread_enable_asynccancel doesn't modify the $rdi
register.  But this isn't guaranteed.  Hence we reload the register after
the calls.

1f3615a1c9 Add missing export of fallocate64 on 32-bit platforms. 
Due to a pasto the fallocate64 interface, introduced in glibc 2.10,
isn't exported for 32-bit Linux platforms.  It is too late for this
now so exported them for glibc 2.11.

9e471dad8e Don't try to cleanup libselinux and libaudit. 
Because we are not shutting down the other threads first another
thread might work on a query before the process shuts down.  In this
case the now uninitialized libselinux and libaudit might be used.
Just don't free the resources.  It's not necessary anyway because
the process is about to terminate.

9437b427ce Fix change to prevent cancel signal in unsafe places. 
The bits tested to decide when to delay the return when switching
off async cancel mode were wrong.  Fix that.  Also close a race
condition in pthread_cancel where the bit indicating the cancellation
is unconditionally set even if the cancel type might have changed.

1a7f254b4b No cancel signal in unsafe places. 
When disabling async cancellation we cannot return from the function
call if the thread is canceled.  This happens when the cancel bits
have been set before async cancel is disabled but the signal hasn't
been sent/received yet.  Delay for as long as necessary since
otherwise the signal might be received in an unsafe context.
