APIs:
- ges_timeline_get_frame_time
- ges_timeline_get_frame_at
- ges_clip_asset_get_frame_time
- ges_clip_get_timeline_time_from_source_frame
Extracting ges_util_structure_get_clocktime to internal utilities adding
support for specifying timing values in frames with the special
f<frame-number> synthax.
summary_:
This way the timeline can handle all priorities for the user
making the API simpler to use.

We need different export decorators for the different libs.
For now no actual change though, just rename before the release,
and add prelude headers to define the new decorator to GST_EXPORT.
With two exceptions:
* ges_clip_create_track_elements_func
* ges_uri_clip_set_uri
which were never declared in headers and should always have been static.
Had to separate timeline_emit_group_added from timeline_add_group
to avoid emitting group-added when the project is being loaded.

This is formally an API break but I am sure no one ever used that and
we should make sure the method is removed as soon as possible because
it has no reason to be exposed.
Summary:
+ [API] GESTrack::commited signal.
+ [API] ges_track_commit_sync
We were emitting commited when timeline_commit was called, which
wasn't very helpful. This commit makes it so we emit commited once
all the compositions have actually been commited.
We also add a synchronous commit method to spare the user
the need to connect to the signal and wait, and update the
documentation.

I got some trouble with
arc land
and I wanted to push the 3 commit coming after this revert as 3
different commits but they ended up being all squash into one single
commit, which is clearly not cool for later bisecting and blaming.
Reverting that commit and re pushing those 3 commits as they were
supposed to be.
This reverts commit 9fe15ef435.
The GNL API changed to go from a model where user could
enable/disable updates in the composition, which leaded to races
in many places, to a model where any positioning change in the
composition is not directly done but 'cached' and then the user
has to commit those changes so they become effective in the media
processing stack.
The new API in GES is pretty similare and is basically copy
pasting this new design.
We still need to see if in some context it would make sense to add
a mode where we would commit any changes ourself at the end of our
operation for basic use cases.
Removed APIs:
ges_timeline_enable_update
ges_timeline_is_updating
ges_track_enable_update
ges_track_is_updating
New APIs:
ges_track_commit
ges_timeline_commit
ges_timeline_append_layer now creates a new layer, adds it to the timeline
and returns it
This code has not been released yet so we can break this API.
This will give us margin for API expansion without breaking ABI.
The ABI restriction will only come in place once we do the first
official release (i.e. 0.x.0).
If a GESTimelineFileSource is added to a layer and:
* It doesn't have specified supported formats
* OR it doesn't have a specified maximum duration
* OR it doesn't have a specifed duration
Then we asynchronously send it to the GstDiscoverer.
If this happens, the state change of the timeline from READY to
PAUSED will happen asynchronously and be completed when everything
has been properly discovered.
