4cbdf43e7d va: Handle input caps change.

b6538e0560 va: Add and use common decode negotiate vmethod.
This vmethod can be used by decoders with the same VA decoder reopen logic:
same profile, chroma, width and height.

Also a new public method called gst_va_base_dec_set_output_state() with the
common GStreamer code for setting the output state, which is always called by
the negotiate vmethod.

In order to do this refactoring, new variables in vabasedec have to be populated
by the decoders:

* width and height define the resolution set in VA decoder. In the case of H264
  would be de coded_width and codec_height, or max_width and max_height in AV1.
* output_info is the downstream video info used for negotiation in
  gst_va_base_dec_set_output_state().
* input_state, from codec parent class shall be also held by vabasedec

4a8ecc2dba va: Add and use gst_va_base_dec_prepare_output_frame().
This helper will do downstream negotiation and later will
allocate the output frame.

H265 and AV1 decoders don't use this approach since their output
frame allocation is different.

de5b76a922 va: Add and use gst_va_base_dec_process_output().
This function will copy the frame, if it's needed, and will apply buffer flags.

The function is used by all the decoders.

ec55017a83 va: allocator: Add hack for no fourcc when surface creation.
This patch adds general mechanism for handling specific hacks. In this
case for jpeg decoder in i965 driver, which cannot create surfaces
with fourcc specified.

From jpeg decoder to the allocator, which creates the surfaces,
there's a non-simple path: basedec pseudo-class adds a hacks guint32
which will be set by actual elements (vajpegdec, in this case) and
basedec will always set the hack to the allocator when the allocator
is instantiated.

97e3f88c20 va: Move common variable need_negotiation to GstBaseDec.
This is a common variable to all decoders, so it's sound to move it to
the base helper.

a2a3c81c85 va: Move back parent_object to each element.
Using GstBaseDec hack to access the parent_object of each element in
the element itself is a bit fragile. It would be better to keep its
own parent object as the usual global variable. It would make it
resistant to code changes.

The GstBaseDec macro to access the parent object now it's internal to
base decoder.
