db7a3b8d3e libs: factor out usages of vaGetConfigAttributes().
Add gst_vaapi_get_config_attribute() helper function that takes a
GstVaapiDisplay and the rest of the arguments with VA types. The aim
is to have thread-safe VA helpers by default.

4481c155b8 encoder: notify the encoder of the submitted packed headers.
Make sure to configure the encoder with the set of packed headers we
intend to generate and submit. i.e. make selection of packed headers
to submit more robust.

14ad694fdc context: move rate-control mode to encoder specific config.
Move usage-specific config out of the common GstVaapiContextInfo.
Create a specialized config for encoding and move rate-control mode
to there.

0eb4070977 context: introduce concept of usage.
Introduce GstVaapiContextUsage so that to explicitly determine the
usage of a VA context. This is useful in view to simplifying the
creation of VA context for VPP too.

3b714c8913 context: move overlay composition to separate files.
Move GstVideoOverlayComposition handling to separate source files.
This helps keeing GstVaapiContext core implementation to the bare
minimal, i.e. simpy helpers to create a VA context and handle pool
of associated VA surfaces.

c85b080688 context: clean-ups. Strip down APIs.
Improve documentation and debug messages. Clean-up APIs, i.e. strip
them down to the minimal set of interfaces. They are private, so no
need expose getters for instance.

71113e4999 encoder: h264: only submit packed headers when required.
Make sure to submit the packed headers only if the underlying VA driver
requires those. Currently, only handle packed sequence and picture
headers.

02e174c8bc libs: add support for rate-control to GstVaapiContext.
Extend GstVaapiContextInfo structure to hold the desired rate control
mode for encoding purposes. For decoding purposes, this field is not
used and it is initialized to GST_VAAPI_RATECONTROL_NONE.

15519ebe3d legal: add per-file authorship information.
Credit original authors on a per-file basis as we cannot expect people
to know all country-specific rules, or bother browsing through the git
history.

d8ffc2c150 libs: drop some public APIs.
Don't expose GstVaapiContext APIs and make them totally private to
libgstvaapi core library. That API would also tend to disappear in
a future revision. Likewise, don't expose GstVaapiDisplayCache API
but keep symbols visible so that the various render backends could
share a common display cache implementation in libgstvaapi.

Try to clean-up the documentation from any stale entry too.

67eea92044 libs: drop GST_VAAPI_IS_xxx() helper macros.
Drop obsolete GST_VAAPI_IS_xxx() helper macros since we are no longer
deriving from GObject and so those were only checking for whether the
argument was NULL or not. This is now irrelevant, and even confusing
to some extent, because we no longer have type checking.

Note: this incurs more type checking (review) but the libgstvaapi is
rather small, so this is manageable.

e65726de8d decoder: drop obsolete functions.
Drop the following functions that are now obsolete:
- gst_vaapi_context_get_surface()
- gst_vaapi_context_put_surface()
- gst_vaapi_context_find_surface_by_id()
- gst_vaapi_surface_proxy_new()
- gst_vaapi_surface_proxy_get_context()
- gst_vaapi_surface_proxy_set_context()
- gst_vaapi_surface_proxy_set_surface()

This is an API change.

e22a863084 decoder: simplify acquisition/release of spare surface.
Introduce gst_vaapi_surface_proxy_new_from_pool() to allocate a new surface
proxy from the context surface pool. This change also makes sure to retain
the parent surface pool in the proxy.

Besides, it was also totally useless to attach/detach parent context to
VA surface each time we acquire/release it. Since the whole context owns
all associated VA surfaces, we can mark this as such only once and for all.

4ca1f3f47c context: allow number of reference frames to be set.
Make it possible to specify the maximum number of references to use within
a single VA context. This helps reducing GPU memory allocations to the useful
number of references to be used.

dba174906a libs: declare _get_type() functions as const.
Declaring a function as const enables better optimization of calls
to the function.
