ae429de8f6 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.

30833f6242 video: Change struct padding from void* to gpointer
gobject-introspection causes inconsistent type information for the
former and we use gpointer everywhere else.

3bf893e12a video: add gst_video_decoder_allocate_output_frame_with_params
It adds a third argument to pass GstBufferPoolAcquireParams
to gst_buffer_pool_acquire_buffer.

If a user subclasses GstBufferPoolAcquireParams, this allows to
pass an updated param to the underlying buffer pool at each
gst_video_decoder_allocate_output_frame_with_params call.

5be3c5f6b2 videodecoder/encoder: Correct GST_IS_*CODER_CLASS macros
They are currently not used, but would result in a compiler error due to wrong

c63db0e104 Revert "videodecoder: expose default query handling function"
Apparently I forgot how gobject works, there is no need to expose
it directly as one can call it from the parent_class pointer

This reverts commit ea9b6a7e3c.

4982188cf7 videodecoder: add option to use default pad accept-caps handling
Add gst_video_decoder_set_use_default_pad_acceptcaps() to allow
subclasses to make videodecoder use the default pad acceptcaps
handling instead of resorting to the caps query that is, usually,
less efficient and unecessary

API: gst_video_decoder_set_use_default_pad_acceptcaps

ea9b6a7e3c videodecoder: expose default query handling function

d2cc76b228 videodecoder: Add transform_meta() vfunc with default implementation
The default implementation copies all metadata without tags, and metadata
with only the video tag. Same behaviour as in GstVideoFilter.

This currently does not work if the ::parse() vfunc is implemented as all
metas are getting lost inside GstAdapter.

af26201429 videodecoder: Add drain() vfunc
drain() is a new vfunc which does what finish() does, while
explicitly requiring the decoder be able to continue processing
data afterward.

8085352fb3 videodecoder: expose getcaps virtual function
Allows subclasses to do custom caps query replies.

Also exposes the standard caps query handler so subclasses can just
extend on top of it instead of reimplementing the caps query proxying.

946dc6b09f videodecoder: Reset last_timestamp_out on new segment
Reset last_timestamp_out when applying the output segment
change, to avoid decoder confusion over new timestamp timelines when
a seamless segment change happens.

Move some locks/unlocks to later when they're actually needed.

40fc306017 videodecoder: make _release_frame external API
... so subclasses can release a frame all the way (also from frame list)
without having to pass through _finish_frame or _drop_frame.
The latter may not be applicable, or may or may not have already
been called for the frame in question.

2f05268517 video: make direct includes work again
Not nice to break people's code if we can avoid it. Could
add a warning in the next cycle, and then require single
includes in the cycle after.

efe9e31b34 videodecoder: getters for pool and allocator
Sometimes the decoder would need to use the pool or the allocator for
something else than just allocating output buffers. For example, the querying
for different parameters, such as asking for a bigger number of buffers to
allocate in the pool.

This patch expose a two getters accessors: one for the buffer pool and the
other for the memory allocator.
