9c6ea9facb Fix stack size and address inconsistency due to executable stack
When a stack is marked executable due to loading a DSO that requires
an executable stack, the logic tends to leave out a portion of stack
after the first frame, thus causing a difference in the value returned
by pthread_getattr_np before and after the stack is marked
executable. It ought to be possible to fix this by marking the rest of
the stack as executable too, but in the interest of marking as less of
the stack as executable as possible, the path this fix takes is to
make pthread_getattr_np also look at the first frame as the underflow
end of the stack and compute size and stack top accordingly.

The above happens only for the main process stack. NPTL thread stacks
are not affected by this change.

439bf404b8 Allow a single-threaded program to cancel itself
There is nothing in the POSIX specification to disallow a
single-threaded program from cancelling itself, so we forcibly enable
multiple_threads to allow the next available cancellation point in the
thread to run.

Also added additional tests to cover various cancellation scenarios.

At least the Linux kernel provides field where the kernel originally
stores the command which is executed by the thread.  The value can
subsequently be overwritten.  The added functions allow to do that for
threads, providing and abstraction around the syscalls or /proc file
system accesses needed.

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.

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.
