fork() kills this entire subsystem and leaves its internals
in an inactive but allocated state, so it's necessary to explicitly restart
everything in order to guarantee behavior

Summary:
memset overwrites the thread value, triggering errors when running tools like
helgrind
attempting an operation on an invalid thread will cause errors naturally,
so zeroing the rest of the struct and ignoring the thread member is fine

Summary:
these effectively prevent locks from being used to synchronize operations
between (non-main) threads, which restricts their usefulness and also
prevents our own unit tests from passing

Depends on D6267

Summary:
a mutex can only have one type, so setting this type onto a recursive mutex
will unset the recursive attribute and cause deadlocks

Well... that's just embarassing... semaphore_destroy() actually takes
the mach task as its first parameter, not the second. This core
amazingly worked very fine on macOS earlier than Sierra.
Fixes T5245
There was trouble with Homebrew's CI to build EFL on a macOS < 10.12
which uses a 10.12 SDK. See PR #13252 on github, Homebrew/homebrew-core
for details.
@fix
this moves a lot of logic that is rare away from the linear/flat asm
path of code so we et fewer l1 cache misses when executing chuncks of
our code. this also reduces the code size and takes some funcs like in
eina_inline_lock_posix.x and makes them real functions to reduce code
size thus better l1 cache usage - only for new/free of locks.
spinlocks, semaphores etc. as these will have no advantage being
inlined but simply bloat out code size instead.
overall this actually reduces efl lib binary sizes 0.4%, so that's a
good sign.
this passes make check and i think i got it right... let me know if i
didn't. i'm also not sure i should just keep the static inlines and
not make the formerly static inline funcs full EAPI ones now... good q.
