it seems that on windows read() and write() won't work with sockets,
so use recv() and send().
Note that this code is still untested on windows, at least the errors
must be fetched using WSAGetLastError() instead of errno directly, but
I don't have a Windows machine I can test.
So yeah, fb_dirty is for marking dirty regions when rendering
directly into the front buffer attached for scanout on a manually
updated display. Absolutely none of those things apply here, so
let's stop doing it.
What we've always wanted when getting the "current" FB is to get
the most recently submit one - this may be current, next, or pending.
Replace ecore_drm2_output_current_fb_get() with a function that gets the
most recent one - ecore_drm2_output_latest_fb_get(). Now callers don't
have to check the next buffer themselves first, and we don't have to
add an API for pending.
Add a function for ecore_evas_drm to call after a page flip happens so
ecore_drm2 can track busy status for fbs itself (including for the fb
that's currently being flipped to scanout)
Also, call the completion function from ecore_evas_drm
When triple buffering we'll have a buffer in ecore_drm2's "next" position.
Until now we've had to query it from the engine then try to re post it.
Also, when generating ticks we need to flip to the current buffer when no
changes have been made to get another callback.
Now a NULL fb to fb_flip will either flip to next, if available, or current
if there's nothing new to flip to.
Now that we have redraws_clear exposed through software generic, we can
use that to do the final buffer swap from the main thread instead of doing
it in outbuf_flush which runs from the render thread.
This becomes more important later when other call sites in the main thread
will perform buffer flips.
When triple buffering it's possible that we'll only need two buffers at
a time for long durations. When we finally call upon a third buffer it
hasn't been used recently enough to do a partial redraw.
By picking the oldest available buffer when multiple buffers are free we
can increase the likelihood of doing partial redraws.
Instead of passing the user data for the page flip callback every time,
set it just once.
This will make it easier to push tick logic into ecore_evas_drm, as there
will be a transitional period where page flips are driven in two places
that don't have access to the same pointers.
To allow using the pageflip completion event to drive timing in the DRM
engine we need to know as soon as possible that a render has been after
a render has been considered if it will cause a page flip or not.
The fn_evas_changed callback sends this information.
Before this commit, function overrides were explicit. That is, you'd
have to explicitly state you were overriding a function instead of
creating a new one. This made the code a tad more complex, and was also
a bit more annoying to use. This commit removes this extra piece of
information.
This means we now store much less information per function, that will
let us further optimise out structures in the future.
Commit 405680e836 changed how hold
events were being sent. Previous code was sending the hold events to
child objects, however after mentioned commit, they were being sent to
main objects. This patch fixes that.

Now that we have recursive locks, the class creation code can be much simpler.
All the code there was essentially our own implementation of recursive locks,
or rather a special case of those.
This is no longer needed.
fix the elm image threaded image preload to be far simpler and
actually threadsafe without blocking the mainloop at all even on
object deletion. this also ensures ar least the first 512M of any
async precached file are loaded in so the preload doesnt stall on
headers that are outside maybe the first 4k of the file. i saw this
happening all over the place in the test i created.

Summary:

this adds a signle mutex (recursive) mutex for all eo objects that is
auto-called by _efl_object_call_resolve() and _efl_object_call_end()
that wrap all eo method calls and since its recursive it can be
blindly called for sub-calls. this will lock all shared objects during
any call to any shared object so only the thread calling now has
access until it releases. not fine-grained but good enough and the
best we can do "simplistically".
Gcc warns eo_child is set but not used here, so remove it.
NB: This should have been removed in previous evas_events commit. Oopise

Gcc warns that these variables are 'set but not used'. After reading
the surrounding code, it turns out they are not actually used, so
remove them.

This moved all the eoid tables, eoid lookup caches, generation count
information ad eo_isa cache into a TLS segment of memory that is
thread private. There is also a shared domain for EO objects that all
threads can access, but it has an added cost of a lock. This means
objects accessed outside the thread they were created in cannot be
accessed by another thread unless they are adopted in temporarily, or
create4d with the shared domain active at the time of creation. child
objects will use their parent object domain if created with a parent
object passed in. If you were accessing EO (EFL) objects across threads
before then this will actually now cause your code to fail as it was
invalid before to do this as no actual objects were threadsafe in EFL,
so this will force things to "fail early".
ecore_thread_main_loop_begin() and end() still work as this uses the
eo domain adoption features to temporarily adopt a domain during this
section and then return it when done.
This returns speed back to eo brining the overhead in my tests of
lookup for the elm genlist autobounce test in elementary from about
5-7% down to 2.5-2.6%. A steep drop.
This does not mean everything is perfect. Still to do are:
1. Tests in the test suite
2. Some API's to help for sending objects from thread to thread
3. Make the eo call cache TLS data to make it also safe
4. Look at other locks in eo and probably move them to TLS data
5. Make eo resolve and call wrappers that call the real method func do
recursive mutex wrapping of the given object IF it is a shared object
to provide threadsafety transparently for shared objects (but adding
some overhead as a result)
6. Test test est, and that is why this commit is going in now for wider
testing
7. Decide how to make this work with sending IPC (between threads)
8. Deciding what makes an object sendable (a sendable property in base?)
9. Deciding what makes an object shareable (a sharable property in base?)
