e398f2c245 libs: surface: rename create function names to init
There are several internal functions with 'create' name, but they
don't create any new structure, but rather it initializes that
structure. Renaming those function to reflect better their purpose.

The GstVaapiMiniObject is obsolete and we need to replace it. This
patch turns GstVaapiContext into a plain C structure with its own
reference counting mechanism.

Also this patch removes unused overlays attributes.

4bb41e6ca3 libs: encoder: h264fei: remove unnecessary check
Issue detected by Coverity

`info_to_pack.h264_slice_header` is always allocated by
gst_vaapi_feipak_h264_encode(), thus checking it to free it afterwards
in doesn't make much sense.  But it requires to be free on the error
path.

There may be a null pointer dereference, or else the comparison
against null is unnecessary.

47b0932911 libs: encoder: h264fei: don't free memory on stack
Issue detected by Coverity

`info_to_pak` variable in gst_vaapi_encoder_h264_fei_encode() is
declared in the stack, but it is free in
gst_vaapi_feienc_h264_encode() as if declared on the heap.

This patch initializes the structure and removes the free.

A non-heap pointer is placed on the free list, likely causing a crash
later.

4c87644914 vaapipostproc: Use level value for skin-tone-enhancement filter.
Currently the parameter of skin-tone-enhancement filter is forced
to zero. In fact it could be set different value by the user.
So create a new property named as "skin-tone-enhancement-level"
for accepting the used defined parameter value.
At the same time, skin-tone-enhancement is marked as deprecated.
When skin-tone-enhancement-level is set, skin-tone-enhancement
will be ignored.

f67ec886a3 libs: decoder: h264, h266: fix g_return_val_if_fail() missuse
g_return_val_fail() documentations says:

  If expr evaluates to FALSE, the current function should be
  considered to have undefined behaviour (a programmer error).
  The only correct solution to such an error is to change the
  module that is calling the current function, so that it avoids
  this incorrect call.

So it was missused in a couple parts of the H264 and H265 internal
decoders. This patch changes that to plain conditionals.

Also, it was included a couple code-style fixes.

f5e1946036 libs: video-format: Make all YUV format available
The YUV formats have no ambiguity for drivers, so we can add them all.
Some old driver(i965) does not implement full get/put image functions
but can use derive image funtions for the YUV format. It does not
report that kind of formats correctly in image query, but will derive
that YUV format image from surface. The dynamic mapping of YUV format
will block that manner.
Adding more YUV format mapping has no side effect. So considering the
legacy driver conformance, we add all YUV formats mapping statically
and dynamic mapping RBG formats

6693be476c libs: h264decoder: do not return error for unhandled NAL unit.
Some streams have error data introducing unknown NAL type. There are
also kinds of NAL types we do not want to handle. The old manner will
set a decoder error when encounter this, which cause a latent crash bug.
The decoder may successfully decode the picture and insert it into DPB.
But there are error NAL units after the AU which cause the post unit error
and make that frame dropped. The later output of the picture still want
to ref that frame and crash.
No need to set decoder error when can not recognize or handle the NAL
unit, just skip it and continue.

The command line:
  gst-launch-1.0 filesrc location=some_name.mjpeg ! jpegparse !
  vaapijpegdec !  videoconvert ! video/x-raw,format=I420 ! vaapisink
will crash on i965 driver because of no pointer check.

We now generate the video format map between GST format and VA format
dynamically based on the image format returned by vaQueryImageFormats.
i965 driver does to report image format of 444P and Y800 forcc, while
the jpeg decoder context VASurfaceAttribPixelFormat use them. We can
not recognize these format and pass a NULL pointer to
gst_vaapi_surface_new_from_formats.
We need to add a pointer check here and let the fallback logic handle
this case correctly.

3ba3966fc3 vaapiencode: enhance how the profile is defined
This code doesn't define the profile used by the internal encoder, but
it used to "predict" which is going to be used and to get the caps
restrictions.

Before the profile was predicted by checking the donwstream caps, but
sometimes they are not defined, setting an unknown profile. In order
to enhances this situation, the encoder asks to internal encoder if it
has one. If so, it is used.

To ask the internal encoder's profile a new accessor function was
added: gst_vaapi_encoder_get_profile()

c06b587819 vaapipostproc: element warning if video direction is unsupported
If the video direction is unsupported by the driver, an element
warning is posted in the bus to notify the application.

gst_vaapi_enum_type_get_nick() was added in the library thus it can
be used elsewhere. It retrives the nick from an enum gtype.

47ff72a6d4 libs: filter: check mirror and rotation caps only once
This patch locks the display before querying the pipeline caps and
stores the mirror and rotation capabilities, thus they are not queried
every time the video direction is set.

a48625d7ff libs: filter: set all color balance values
When set multiple settings of color balance like hue, saturation,
brightness and contrast for vaapipostproc, they should be set as
parameters of color balance filter, at the same color balance
filter calling.

Otherwise, multiple color balance filter calling will cause
previous setting get reset by the last calling with default value.

Fixes #182.

e96a435756 libs: videopool: fix undocumented behavior and counting
gst_vaapi_video_pool_reserve_unlocked() hit an undocumented behavoir
because it locks twice the same mutex.

Also, n had different meanings in the current code: as an increase
value and as a new total of allocated surfaces.

This patche removes the undocumented behavoir (usually a deadlock) and
fixes the meaning of n as the new total of allocated surfaces.
