The code started out with bits form resolv/resolv_conf.c, but it
was enhanced to deal with directories and FIFOs in a more predictable
manner. A test case is included as well.
This will be used to implement the /etc/resolv.conf change detection.
This currently lives in a header file only. Once there are multiple
users, the implementations should be moved into C files.
The missing dependencies result in failures like this if make check
is invoked with sufficient parallelism for the debug subdirectory:
FAIL: debug/tst-chk2
FAIL: debug/tst-chk3
FAIL: debug/tst-chk4
FAIL: debug/tst-chk5
FAIL: debug/tst-chk6

900778283a ("htl: make pthread_spin_lock really spin") made
pthread_spin_lock really spin and not block, but the current users of
__pthread_spin_lock were assuming that it blocks, i.e. they use it as a
lightweight mutex fitting in just one int.
__pthread_spin_wait provides that support back.
This should be unconditionally set to match the common implementation,
and fixes multiple test failures related to sprintf.

Now that binutils-gdb has gdbserver at top level, an extra
--disable-gdbserver configure option is needed when configuring
binutils from a git checkout to avoid it also building gdbserver
unnecessarily (although fairly harmlessly). This patch updates the
options used in build-many-glibcs.py accordingly (although this might
end up not being needed depending on what happens regarding whether
gdbserver gets built for host != target).
Tested with a build-many-glibcs.py compilers build for
aarch64-linux-gnu using binutils-gdb master.
Improve the random memcpy benchmark. Double the number of copies and
increase the memory sizes tested to 512KB. Add a more detailed
distribution of memcpy alignment and sizes up to 4096 based on SPEC2017
traces.

They were not getting used anyway.
Also do not make libsupport use them, it would make tests using it have
to be made to link against libmachuser for gsync_wait.
Particularly on CPUs without ERMS, the string instructions are slow,
so it is unclear whether this architecture-specific implementation is
in fact an optimization.
so it gets shared by nptl and htl. Also add htl versions of thrd_current and
thrd_yield.
