membar_ops(3): Add some automatic tests.

These tests run two threads for five seconds each to try to trigger
races in the event of broken memory barriers. They run only on
machines with at least two CPUs; on uniprocessor systems there's no
point -- the membars can correctly just be (instruction barrier)
no-ops.

Add tests for missing libc catalog entries

Add ATF tests for atomic_ops(3).

Register micro-UBSan ATF tests in the distribution

Populate distrib files, mtree lists and add the entry in Makefile to
include the new code.

Add a link-time test for __sync_* primitives (see PR 48368) - this
will allow us to notice missing functions during the build, instead
of when compiling arbitrary pkgsrc stuff later.

rename the only use of HAS_SSP in the tree to HAVE_SSP.

Don't include bsd.sys.mk; like sys.mk it is supposed to be used only
internally.

Add most system calls for POSIX extended API set, part 2, with test cases:
faccessat(2), fchmodat(2), fchownat(2), fstatat(2), mkdirat(2), mkfifoat(2),
mknodat(2), linkat(2), readlinkat(2), symlinkat

faccessat(2), fchmodat(2), fchownat(2), fstatat(2), mkdirat(2), mkfifoat(2),
mknodat(2), linkat(2), readlinkat(2), symlinkat(2), renameat(2), unlinkat(2),
utimensat(2), openat(2).

Also implement O_SEARCH for openat(2)

Still missing:
- some flags for openat(2)
- fexecve(2) implementation

Add regression test for cdbr(3) and cdbw(3).

Remove ieeefp subdirectory.

Turn warns on for all tests and fix all the bugs.

Add the new 'termios' subdirectory.

atf-ify the various locale tests

Add TLS support infrastructure. For dynamic binaries, ld.elf_so exports
_rtld_tls_allocate and _rtld_tls_free. libpthread uses this functions to
setup the thread private area of all new threads. ld.elf_so is
responsible for setting up the private area for the initial thread.
Similar functions are called from _libc_init for static binaries, using
dl_iterate_phdr to access the ELF Program Header.

Add test cases to exercise the different TLS storage models. Test cases
are compiled and installed on all platforms, but are skipped on
platforms not marked for TLS support.

This material is based upon work partially supported by
The NetBSD Foundation under a contract with Joerg Sonnenberger.

It is inspired by the TLS support in FreeBSD by Doug Rabson and the
clean ups of the DragonFly port of the original FreeBSD modifications.

Moving t_hsearch - belongs in stdlib/

Another test moving: lib/libc/t_inet --> lib/libc/inet/t_inet_network

Last one for today: move t_ptm test from lib/libc/ to lib/libc/ttyio/

Continuing the (re)organization of the lib/libc atf regression tests

The nsdispatch test belongs in libc/net and not in libc

Move t_mktime and t_strptime to their own ..../time/ subdirectory.

(Concurrence from christos@)

Put the atexit test where it belongs - in libc/stdlib/

Move the servent and protoent tests to src/tests/lib/libc/net/ (where
they should have gone initially).

By request, put the getaddrinfo test in tests/lib/libc/net/

Atf-ify the getaddrinfo test, with updated "golden" output files.
