so. on linux signals are delivered to the main process thread/loop.
thats' where signal handlers are set up and always run. this is sane.
it's predicatble. but of course this is not the same in bsd land.
there "just send the signal to any old thread and call the signal
handler there" seems to tbe the order of the day. this explains why
wer are losing sigchld signals in edje_cc - it's heavily threaded and
bsd is just randombly picking a thread to call it on.
this fixes that. in theory. i hope. i can't test, but putting it in to
share

This is a reccurring compatibility issue...
MAP_ANONYMOUS is not defined on OSX, but MAP_ANON is.
I know MAP_ANON is marked as deprecated in the Linux man
pages, but it has the benefit of being more portable.
This is heavily inspired from Eo_Id infrastructure. Main change
are that the lower bit are always guaranteed to be zero and ignored
by all function. Also it may be a little bit less efficient in some
case, but we will tune it once we have real life usage of it.
Eo won't be migrated for 1.18 to it as Eo_Id is deeply integrated
and it is quite risky to touch it so close from a freeze. This can
wait.
In case of failure within eina_lock_new() (posix), a
pthread_mutexattr_t would have been left in an initialized state,
without any deinitialization being called.
Consequences would have been implementation defined.
DragonFlyBSD has pthread_setname_np but no pthread_setaffinity_np;
we still need to include pthread_np though.

Cancelling a promise will fulfill it but won't actually free the memory. This
memory is under custody of the owner, who must either call value_set or
error_set to finish it.
Now when dealing with pointer types, we will not get pointer to
pointer semantics in callbacks and eina_promise_owner_value_set
for Eina_Promise.
It will work as expected:
Eina_Promise_Owner* promise = eina_promise_add();
void* p = malloc(sizeof(T));
eina_promise_owner_value_set(promise, p, &free);
The call to eina_promise_then steals the first ref'count, so it is
possible that the promise is freed after the eina_promise_then,
so we need to eina_promise_ref before eina_promise_then.
We do properly unref promise while calling all the then callback. There
is no need to check it a second time (which actually lead to a 100%
bad access).
T3759
Eina_Error is not passed by pointer anymore, which could cause invalid
pointer access in promise compositions (all and race).
Also added Eina_Promise* to prototypes.
this fixes T3638

a note... thanks so much to aerodynamik for spotting this. i'm rather
surprised coverity didn't spot this... unless someone said to "shut up
coverity you're wrong" and they should not have.
i also might have expected compilers to spot this too... and add a
warning.
anyway ... this was a seriously subtle bug that could have caused all
kinds of havoc in efl. keys that are different may be compared to be
the same. it could get ordering wrong and sorting thus maybe insert
keys that cannot be found anymore and oh so much more besides.
rthis replaces double a == double b with a macro that keeps a close
enough range using epsilon (which is the error range for a dobule).
this fixes T3245
this should fix T3245
this is basicall where we go double a == double b and due to precision
issues this may not always be right, but this means that the
equivalent now checks for "really close values" rather than perfectly
exact.

This is done on an attempt to permanently fix our Windows port. Windows
doesn't have MIN/MAX, so we should always do a ifndef/define in every
piece of code that use it. Of course we always forget and it take times
to notice and fix. We have over the year added it in many private
headers, but as the issue continue to raise again and again, I prefer
to get this fixed in our main header.
Added eina_promise_race function that composes multiple
promise objects into a new promise which is fulfilled
when one of the promises are fulfilled, or fails
when one of the promises have failed.
Add a way for users of the promise owner to get notified when a
promise progress is registered. Also added a convenience composition
function that creates a promise which is fulfilled when another
promise has a progress notification.
