integration: make test_basic be two concatenated clips.
basexmlformatter: Only set timeline auto transitions when done loading.
pipeline: add a get_mode method.
ges-audio-track: Change contructor prototype.

We return an AudioTrack.
timeline: when there are no objects anymore, set duration to 0.
container: resort children after prepending an element.
trackelement: update control bindings correctly.

When duration or inpoint change, we need to remove edge control points,
and set new control points with interpolated values.
Also when duration == 0, we need to remove all control points, as otherwise
the controller will raise !is_end assertions.
It's the duty of the application to set keyframes back when duration gets
!= 0 again.
trackelement: split bindings correctly.
tests: Fix make distcheck

We need to make sure that we can write to the directory where we save
project files, so doing it in the tmp folder.

+ Properly dist test data files
tests: Give more debugging info when samples could not be generated
tests: fix NULL pointer dereference, ternary operator silliness and message type use
python: Do not initialize GES at import time
integration: Add titles test
Remove acinclude.m4 as we do not use it

and it is anyway removed by autogen.sh
ges: Remove custom clip

If you want a custom clip then you have to subclass GESClip,
This class was pre historicall and only used for testing purposes, we
have GESTestClip for that.

clip: Remove the ges_clip_fill_track method

Its was only use by the old custom source which is dead now.

API:
    Remove ges_clip_fill_track

trackelement: Simplify the way we handle children properties

So subclass do not have to implement a new logic all the time, but
instead can use a simple method to add properties as needed.
tests: Let use 20 sec to execute tests
tests: Make use of g_assert_no_error when it makes sense
ges-clip: when a child, is removed, disconnect from its notifies.
