This has not been used for a while and is not even buildable after our
switch to meson. It was a niche to start with given that it needed the
PS3 OS to run on. I asked for any remaining users at EDD and on the list
but heard nothing. Time to remove.

Revert "eina: remove no longer used function _eina_thread_queue_msg_block_real_free"
This reverts commit 695b44526c.
Revert "eina/threadqueue: use mempool_del for hash free function"
This reverts commit b0cb3b935a.
Revert "eina_thread_queue: use normal mempools for block allocation"
This reverts commit 14ae3e3dec.
Why? Threadqueue is a highly performance sensitive API.
_eina_thread_queue_msg_block_new() may be called quite often. Doing a
hash lookup to then find a mempool handle to then allocate from was
not the same as what was there and was going to be far more costly.
This would have actual performance impact as we have to compute a hash
and rummage through a hash, hunt for an environment var too. The
original code looked at a spare block pool where blocks *MAY* be of
different sizes (not always the same size so using a mempool is
actually wrong and will stop threadqueue from being able to send
larger messages at all). If you send large messages, larger blocks would
have been allocated and put in this pool. In almost all cases the first
item in the pool would be big enough so we don't hunt and the find pulls
out the first memory, resets the fields that are needed and returns that
block. If it needs a bigger one, it does hunt. This is going to be
rare that such big blocks are needed so I never tried to optimize this
(but it could be done with an array of sizes to make a walk to find
the right sized element cheap if the need arises).
Performance dropped quite a lot. On aarch64 The above mempool usage
dropped message rate from 1037251 msg/sec to 610316. On x86 it was even
worse. It dropped from 2815775 msg/sec to 378653.
So backing this out sees the message rate is 7.4 times faster and on
aarch64 it's 1.7 times faster.
So moving to a mempool was actually just wrong (size is not always the
same). Also this ended up with a mempool of 64k for thread queue blocks even
if we only sent messages sporadically, as opposed to a single 4kb
block. So backing this out saves memory by only having 1 or 2 4k blocks
around most of the time, not a 64k mempool.
So the above patch then follow-on patches were done without accounting
for the performance implications. There were good reasons to do what I
did - because this code was highly tuned even to the point where I
used atomics instead of locks specifically to cut down some contention
overhead. Beware when you change something that there may be steep
performance implications. 7.4 times faster to go back to what was
there is a great example.
close all fd's starting at a given fd and then leving out an exception
list specially passed, if any. useful for fork+exec. this uses it in

This is never actually used since meson generates eina_config.h
from scratch. Apart from the byteswap checks done in the previous
commit, all of the other things already seem to be done by meson,
so just remove it.
For one, eina_config.h.in is never used by anything since meson,
so doing any checks in it and expecting them to work is wrong.
Byteswaps are one place where this is the case, so move the
checks back in their appropriate place.
Summary:
there is not any way to determine that this function has failed other
than to check this pointer, so ensure that it always has a value which
is meaningful in failure cases

do it once and remember the result from the first one. drops overhead
for sure by a chunk i actually could see in perf reports like about 1-2%
of cpu...
this is a performance optimization. it brings in a "stat generation".
for now it's disabled by default so we retain previous behavior. this
stops eina file from opening and stating a file every time you open
... it only does it if stat generation is off, or, if the generation
changed since the last time it opened that file. this makes cache hits
not have a 3 syscall cost (open+fstat+close). this optimizes that
lower end of things path. but .. it comes at a cost. if the file
changes before generation ticks over (which this forces to tick over
every time the loop exits idle by default).
now here is something to ask.
1. should we have this on by default and accept the "inexactness"
since you can eina_file_statgen_next() before any call that would do
i/o to force it to look at the real file stat info...
2. should we tick over every idle enter OR every N idle enters or
every frame we render instead? ... i want to avoid getting a timestamp
or having a timer interrupt often... so what should we do?
at least this introduces the idea, some api's and an env var to turn
this on. it definitely cuts down syscalls during things like creation
of widdgets or objects in large batches etc.

on linux open supports() O_CLOEXEC. add test case for this in meson
build and ifdef. this rolls 3 syscalls into 1 as we were doing open,
then fnctl to get and fcntl to set flags.
less syscalls is a good thing as syscalls are not cheap on some
architectures or systems. I've seen a syscall on 1 system take 2-3x
as long as another and another syscall in the same 2 system
comparison take 10x as long. depending on the syscall you may only
have a budget of something like 5000 syscalls "per frame" (60fps)
before you spend all of your frame time just in syscalls not
doing any processing, so we should keep these down if possible
and that is what this does.
it doesn't matter if this doesn't work with eina_debug since this isn't
meant to be used for that kind of debugging
