Summary:
When we are trying to set an FB onto a plane, we need to update the
plane state values to reflect any changes in the FB. Failure to do
this will result in Atomic Commit failures as the plane state values
will not match what the FB is.

Summary:
When we add a plane we need to add it to the list before doing the atomic
test to ensure we're testing new state that includes the plane, and to
ensure the next screen update includes the plane we just added.

The plane state struct needs the fb id for drm updates, and the plane
state can be updated even if it's pointed to by a dead plane.
Dead planes need to keep their fb so we can properly handle the fb
lifetime.
Removes the previous "busy" flag, as now we might have an fb attached to
multiple outputs at once, and need to be careful to destroy them only
after they've been removed from all outputs.
Removed the old "busy_set" API which nothing used, and renames fb_destroy
to fb_discard to make it more clear that it's not immediately destroyed.
It's all beta api, so I can do this.
Small patch which starts to implement refcounting on framebuffer
objects. This will be needed so that we do not free FB objects while
they are on the screen.

We keep planes on the plane list to ensure a released plane is removed
from display - however this means that if a caller starts messing with
a plane after release, that it could potentially reposition a plane it
doesn't own anymore.
Use EINA_SAFETY macros to prevent this.
The release flag is actually less useful than the existing in_use flag
for determining if a plane is unused. If a new plane is assigned before
the next flip cleans up released planes, then it can point to a released
plane state, and both it and the previous user will be freed on the next
commit, leaking a plane.
Putting the flag in the plane structure fixes this while still allowing us
to keep released planes around to ensure a recently released plane is
cleared from atomic state.
If we don't do a flip test, the atomic state isn't updated. This fixes
a potential problem where the last operation in state preparation is
a release - the following commit wouldn't include state from the release.
As we cannot immediately remove a plane from an output, due to needing
an atomic commit to actually remove the plane from screen, we can use
a 'release' flag to indicate that a given plane needs removal from the
screen during our next atomic commit.

As we need to be able to commit a new plane state for any released
planes, we should not be removing them from the output list just yet.

Unfortunately the plane sized returned from the cursor plane query isn't
a limit, it's an exact size. Sometimes you can use a different size,
but that's completely hardware dependent - so stick to the advertised
size.
This will simplify a bunch of API that would otherwise have to pass in
both output and plane - and in some cases we might not have the output
handy anyway.
As there is nothing inside this function which requires any Atomic API
calls, this #ifdef can be removed and the function can then still be
used to assign Primary planes for non-atomic use cases.

When we do an atomic commit, we need to know where to place a given
plane (in the case of overlays) in relation to the CRTC, so provide an
API function that can be used for that purpose.

As we will need the plane state source values when we do an atomic
commit, we can store them when plane_assign is called as we already
have the FBO available.

This patch adds a new file where we can store any additional functions
we may need to work with hardware planes. Currently the file contains
a public function that can be used to assign a given Ecore_Drm2_Fb to
a hardware plane
