videoencoder: add API to push subframes
...
Introduce a new API so encoders can split the encoding in subframes.
This can be useful to reduce the overall latency as we no longer need to
wait for the full frame to be encoded to start decoding or sending it.

No semantic change, I'm going to reuse all those functions in a new

Use G_DEFINE_AUTOPTR_CLEANUP_FUNC unconditionally
...
Since we started depending on GLib 2.44, we can be sure this macro is
defined (it will be a no-op on compilers that don't support it). For
plugins we should just start using `G_DECLARE_FINAL_TYPE` which means we
no longer need the macro there, but for most types in base/gst-libs we
don't want to break ABI, which means it's better to just keep it like it
is (and use the `#ifdef` instead).

video: GST_EXPORT -> GST_VIDEO_API
...
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.

videoencoder: implement QoS
...
It allows encoders to detect and drop input frames which are already
late to increase the chance of the pipeline to catch up.
The QoS logic and code is directly copied from gstvideodecoder.c.

Sometimes the encoder would need to use the allocator for something else than
just allocating output buffers, for example, querying different parameters.
This patch expose a getter accessor for the negotiated memory allocator.
