We clearly uniquely identify assets by both their IDs and their
extractable type, and we should make sure that you can have a
TrackElement and a Clip with the same ID.
There is one exception in our implementation which is GESFormatter
because we treat their subclasses as 1 type with different IDs.
Corrected typo that attached project_loaded_cb, rather than error_loading_asset_cb, to ::error-loading-asset, which meant data.error would be left unset if an error occurred in loading.

Implement lazy loading asset cache so gesdemux use the formatters
assets while GES hasn't been initialized.
And set extensions to temporary files as some formatters require
the information (otio)
Uses the file extension as hint falling back to the default formatter
if none is found
Make use of that function in when saving a project and not formatter
is specified.
This method is useful when implementing a formatter outside
GES that end up converting to xges and uses the default formatter
to finally load the timeline.
Adding a property to let the application know
Also make sure that the duration of nested timeline assets is reported
as CLOCK_TIME_NONE as those are extended as necessary.
And make a difference between asset duration and their max duration
As nested timelines can be extended 'infinitely' those max duration
is GST_CLOCK_TIME_NONE, but their duration is the real duration of
the timeline.
When we have nested timelines, we need to make sure the underlying
formatted file is reloaded when commiting the main composition to
take into account the new timeline.
In other to make the implementation as simple as possible we make
sure that whenever the toplevel composition is commited, the decodebin
holding the gesdemux is torn down so that a new demuxer is created
with the new content of the timeline.
To do that a we do a NleCompositionQueryNeedsTearDown query to which
gesdemux answers leading to a full nlecomposition stack
deactivation/activation cycle.
It was making no sense to consider it an empty timeline when the user
had passed the project URI when requesting the asset. Usually user
use `ges_project_new` with the URI but it is also valid to use
`ges_asset_request` with the uri as ID so let's handle that properly.
Subprojects simply consist of adding the GESProject
to the main project asset list. Then those are recursively
serialized in the main project in the <asset> not, when deserializing,
temporary files are created and those will be used in clips
as necessary
