libpthread: Fix expected symbols on alpha and hppa.

These have PTHREAD__ASM_RASOPS and define a different subset of
symbols which get exported. None of these pthread__ras_* and
pthread__lock_* symbols _should_ be exported but we can fix that in a
future revbump.

Add USE_SHLIBDIR=yes to a number of Makefiles for the libraries used
by /sbin/{zfs,zpool,mount_zfs}. The general effect is to move them
from /usr/lib to /lib. Compatibility links are installed in /usr/lib
and nothing that is installed, say in /usr/pkg, appears to break.

With this, it is possible to have a /var and /usr mount using ZFS
legacy mounting early on in the boot process.

Run tested on amd64 and i386 and compile tested on evbarm.

Replace the link command for libpthread.a so that we create a single section
with all the libpthread symbols in it.
This makes -lpthread behave like to -Wl,--whole-archive -lpthread.

This avoids a situation where threaded static binaries use some libc thread
stubs, which are racy.

Fixes PR lib/54001: call_once2_32, call_once2_static test cases failing on
amd64 since gcc7 import.

Add a complete C11 threads(3) implementation

C11 Thread support library is a portable threading C API between OSs,
similar to std::threads in the C++ world.

The library is implemented as a thin shim over POSIX interfaces.

NetBSD implements the API as a part of the POSIX threading library
(libpthread(3)).

C11 threads(3) are in the process of making them an integral part
of the POSIX standard. The interface has been implemented in major
OSs and used with stopgap libraries for older versions of them.

C11 threading library is already used (with a stopgap implementation)
in the NetBSD distribution in MESA.

Original implementation by myself from 2016.

ATF tests are new and cover almost all interfaces.

Proposed on tech-userlevel@.

Implement support for "pshared" POSIX semaphores.

We can't build those three with MKSANITIZER, they are used too early.

let these use the same setting as the rest of the tree.
the performance difference is marginal and this allows
dtrace ustack() to work better.

Add pthread_getcpuclockid(3)

Allow for arbitrary MI scheduler implementations.

A concrete result is enabling unpatched libpthread to run on the
rumprun stacks (e.g. Xen and bare metal) with a non-NetBSD scheduler.
Those schedulers hook into the existing _lwp_frobnitz() NetBSD syscall
interfaces (well, "syscall" interfaces in that scenario ;)

More specifically about the change itself:

1) instead of calling _lwp_makecontext() followed by _lwp_create()
and passing the entry point in ucontext_t (MD) through the calls, roll
the calls into pthread__makelwp() and allow alternate implementations
for that MI interface.

2) allow compile-time overriding of __lwp_gettcb_fast() or
__lwp_getprivate_fast, which are inline and leak MD scheduler/thread
details into libpthread


Additionally, two small nits:

I) define LIB=pthread before including mk.conf so that it's possible
to test for LIB==pthread in mk.conf

II) make it possible to leave out pthread_cancelstub.c. This is required
by the current implementation of rumprun-posix (i.e. rumprun on
POSIX hosts) due to symbol collisions. It needs to be fixed properly
some day, but for now allows an almost-correct libpthread to run.
I am sure @justin will be happy to explain the details ;)

MKCOMPAT fixes for when compat MACHINE_CPU != normal MACHINE_CPU

Use MACHINE_CPU for m68k. Use similar logic for both tests.

Some architectures can't create unwind tables without the frame pointer,
so don't use -fomit-frame-pointer on those.
