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.
Except for the weird _Eina_Mempool_Backend_ABI1/ABI2 work-around which is
completely internal and probably is of interest to noone (the only person
on Earth who will be interested in it in a decade will hate me for skipping
it).
It looks like doxygen doesn't appreciate having a group inside a group of
the same name and simply ignores any documentation coming from the parent
one.
Since the .x is included from the .h, it is always already inside the
group so simply remove the directive from the .x.
This fixes the documentation for all the functions which are declared and
documented in the .h and implemented in the .x.
