By passing NULL to `g_signal_new` instead of a marshaller, GLib will
actually internally optimize the signal (if the marshaller is available
in GLib itself) by also setting the valist marshaller. This makes the
signal emission a bit more performant than the regular marshalling,
which still needs to box into `GValue` and call libffi in case of a
generic marshaller.
Note that for custom marshallers, one would use
`g_signal_set_va_marshaller()` with the valist marshaller instead.
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.
