the very call to start a gc thread!

on a 128-bit boundary like we do on amd64. The padding within the struct
made sure the state was properly aligned *within* the struct, but since the
alignment restriction on the struct itself was only 64-bit, the required
alignment was not guaranteed. We just got lucky.

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.

a failure to lock the _atfork_mutex after forking. Tested by ajacoutot@

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.

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.
