The inspiration and name of MACHINE_CPU come from NetBSD, although the way to
provide it to Makefiles is completely different.

the use of spinlocks and malloc. All needed memory is allocated upfront
and _thread_kern_sig_defer/undefer() is now used to protect critical
sections. okay guenther@

internally when and where required. Macros in <stdio.h> are updated
to automatically call the underlying functions when the process is
threaded to obtain the necessary locking. A private mutex is added
to protect __sglue, the internal list of FILE handles, and another
to protect the one-time initialization. Some routines in libc that
use getc() change to use getc_unlocked() as they're either protected
by their own lock or aren't thread-safe routines anyway.
committing on behalf of and okay guenther@ now that we have install
media space available.

for FILEs that don't have real file-descriptors: the fake FILEs
used internally by snprintf/asprintf/vfprintf and friends now avoid
unnecessary locking by calling the internal __vfprintf() routine
directly and we do want to do locking on FILEs created with funopen().

Not sure what's more surprising: how long it took for NetBSD to
catch up to the rest of the BSDs (including UCB), or the amount of
code that NetBSD has claimed for itself without attributing to the
actual authors.

instead of the generic pthread macros since free(3) uses __arc4_getbyte()
when freeing small sized allocations and the generic pthread macros call
malloc(3).
- eliminate passing pointers to a static variable with global scope (rs)
for additional code clarity and reduction.
- shlib minor bumps for libc and libpthread due to new functions.
From andreas@ with some bits from me. okay tedu@ marc@ w/some spot

vfork() has only one semantic: "parent stalls until child does execve
or exit" and no other semantic. it is unfair to act as if pthread
vfork() suddenly lacks that semantic.

isolate its usage to libpthread only and replace with generic non-static
mutex support in the one place it is needed:
- remove _FD_LOCK/UNLOCK from lseek and ftruncate in libc and make the
functions weak so that libpthread can override with its own new
versions that do the locking.
- remove _thread_fd_lock/unlock() weak functions from libc and adjust
libpthread for the change.
- add generic _thread_mutex_lock/unlock/destroy() weak functions in libc
to support non-static mutexes in libc and add libpthread and librthread
implementations for them. libc can utilize non-static mutexes via the
new _MUTEX_LOCK/UNLOCK/DESTROY() macros. Actually these new macros can
support both static and non-static mutexes but currently only using
them for non-static.
- make opendir/closedir/readdir/readdir_r/seekdir/telldir() thread-safe
for both thread libraries by using a non-static mutex in the struct
_dirdesc (typedef DIR), utilizing it in the *dir functions and remove
remaining and incorrect _FD_LOCK/UNLOCK() use in libc.
- add comments to both thread libraries to indicate libc depends on the
current implementation of static mutex initialization. suggested by
marc@
- major bump libc and libpthread due to function removal, structure
change and weak symbol conversions.
