0b2848fc32 va: postproc: update passthrough and reconfigure pads 
Added helper function _update_passthrough() which will define and set
the pass-through mode of the filter, and it'll either reconfigure both
pads or it will just mark the src pad for renegotiation or nothing at
all.

There are cases where both pads have to be reconfigured (direction
changed, for example), other when just src pad has to (filters
updated) or none (changing to ready state).

The requirement of renegotiation depends on the need to enable/disable
its VA buffer pools.

This patch sets pass-through mode by default, so the buffer pools
aren't allocated if no filtering/direction operations are defined,
which is the correct behavior.

f7eb93e22b va: vpp: fix a wrong caps logic in vpp_transform_caps(). 
The current gst_va_vpp_transform_caps return such as:
  video/x-raw(memory:VAMemory), width=(int)[ 16, 16384 ], height=(int)[ 16, 16384 ],
  interlace-mode=(string)progressive, format=(string){ NV12, I420, YV12, YUY2, RGBA,
  BGRA, P010_10LE, ARGB, ABGR, VUYA }; video/x-raw(memory:DMABuf), width=(int)[ 16,
  16384 ], height=(int)[ 16, 16384 ], interlace-mode=(string)progressive, format=(string)
  { NV12, I420, YV12, YUY2, RGBA, BGRA, P010_10LE, ARGB, ABGR, VUYA }; video/x-raw,
  width=(int)[ 16, 16384 ], height=(int)[ 16, 16384 ], interlace-mode=(string)progressive,
  format=(string){ VUYA, GRAY8, NV12, NV21, YUY2, UYVY, YV12, I420, P010_10LE };
  video/x-raw(memory:VAMemory), width=(int)[ 1, 2147483647 ], height=(int)[ 1, 2147483647 ],
  interlace-mode=(string)progressive; video/x-raw(memory:DMABuf), width=(int)[ 1, 2147483647 ],
  height=(int)[ 1, 2147483647 ], interlace-mode=(string)progressive; video/x-raw, width=(int)
  [ 1, 2147483647 ], height=(int)[ 1, 2147483647 ], interlace-mode=(string)progressive

Which is not correct. It mixes the template caps and the input query caps together.
The correct way should be: clip the template caps with the input caps(remove format
and rangify size). The correct answer should be:
  video/x-raw(memory:VAMemory), width=(int)[ 16, 16384 ], height=(int)[ 16, 16384 ], interlace
  -mode=(string)progressive, format=(string){ NV12, I420, YV12, YUY2, RGBA, BGRA, P010_10LE,
  ARGB, ABGR, VUYA }; video/x-raw(memory:DMABuf), width=(int)[ 16, 16384 ], height=(int)[ 16,
  16384 ], interlace-mode=(string)progressive, format=(string){ NV12, I420, YV12, YUY2, RGBA,
  BGRA, P010_10LE, ARGB, ABGR, VUYA }; video/x-raw, width=(int)[ 16, 16384 ], height=(int)[ 16,
  16384 ], interlace-mode=(string)progressive, format=(string){ VUYA, GRAY8, NV12, NV21, YUY2,
  UYVY, YV12, I420, P010_10LE }

2e9a096282 va: vpp: Add raw buffer copy when needed. 
Just like the decoder, the vapostproc also needs to copy the output
buffer to raw buffer if downstream elements only supports raw caps
and does not support the video meta.

The pipeline like:
  gst-launch-1.0 filesrc location=xxxx ! h264parse ! vah264dec ! \
  vapostproc ! capsfilter caps=video/x-raw,width=55,height=128 ! \
  filesink location=xxx
needs this logic to dump the data correctly.

fixes: #1523

688ade3cfc va: vpp: fix frame copy 
There were two problems with frame copy:

1. The input video info are from the format color, not form the allocated VA
surface, it's needed to update the sink video info according with the
allocator's data.

2. The parameters of `gst_video_frame_copy()` were backwards.

f7aafa74ab va: vpp: transform_size() must return FALSE 
transform_size() basetransform vmethod is used when there's no output buffer
pool and allocates a system memory buffer. With VA this cannot be allowed, since
it needs VASurfaces to process.

Thus transform_size() is not required, but to play safe let's return FALSE.

a29b56008a va: vpp: don't break passthrough if no color balance required 
The function `_add_filter_cb_buffer()` returned TRUE if no color balance filter
are required, but that's is wrong, since it will break the passthrough. This
patch return FALSE which is the correct value for the situation.

fbbf9c629a va: allocator: add _set_format() and _get_format() 
Since allocators keep an available memory queue to reuse, video format and usage
hint are now persistant while allocator's memories are around.

This patch adds _set_format() and _get_format() for both VA allocators.

_set_format() validates if given format can be used or reused. If no allocated
surface previously it creates a dummy one to fetch its offsets and
strides. Updated info is returned to callee.

GstVaPool uses _set_format() at config to verify the allocator capacity and to
get the surfaces offsets and strides, which are going to be used by the video
meta.

Allocator extracted caps are compared with caps from config and if they have
different strides or offsets, force_videometa is set.

A new bufferpool method gst_va_pool_requires_video_meta() is added return the
value of force_videometa. This value is checked in order to know if decoders
need to copy the surface if downstream doesn't announce video meta support.

666eedc215 va: caps: centralize caps feature discovering 
These function were repeated in the different implemented
elements. This patch centralize them.

The side effect is dmabuf memory type is no longer checked with the
current VAContext, but assuming that dmabuf is a consequence of caps
negotiation from dynamic generated caps templates, where the context's
memory types are validated, there's no need to validate them twice.
