Add gst_vc1_parse_slice_header() function to parse slice headers as
described in 7.1.2. Slice layers are optional and allowed in advanced
profile mode only. Picture header, if available (PIC_HEADER_FLAG),
is parsed but not recorded because it shall be the same as that was
previously parsed with gst_vc1_parse_frame_header().
This fixes SA00049.vc1 conformance test.

Fix decoding of DIFF2 or NORM2 bitplanes with an odd number of macroblocks.
In particular, account for the first bit that was already parsed so that to
avoid a buffer overflow after all pairs are parsed.
This fixes SA00040.vc1 conformance test.

Rename dqsbedge to dqbedge. The intent is that we can only have a single
boundary edge selector, depending on the value of dqprofile. So, dqbedge
represents DQSBEDGE if dqprofile == GST_VC1_DQPROFILE_SINGLE_EDGE, or
DQDBEDGE if dqprofile == GST_VC1_DQPROFILE_DOUBLE_EDGE.
The former dqbedge field is marked as unused and can be removed on the
next gst-plugins-bad version that allows ABI changes.

Fix parsing of VOPDQUANT when DQUANT == 2. In particular, DQUANTFRM is
not present in the bitstream in this case and it shall be derived to
the default value of zero (7.1.1.31.1).

Fix calculation of ALTPQUANT when DQUANT == 1. PQDIFF alters ALTPQUANT
in any case. See 7.1.1.31.6.

Fix parse_vopdquant() to correctly parse DQPROFILE, which is 2 bits
instead of a single bit.

The standard specifies that when slice_beta_offset_div2 is not present
in the slice header, then the value of slice_beta_offset_div2 shall be
inferred to be equal to 0.

Re-uses existing blitting code and also means we can support
a lot more video formats out of the box, hence avoid unnecessary
pixel format or colour space conversions.

Forward allocation queries on video sink pad instead
of discarding them.
This allows the upstream elements to use the allocation
parameters or pools from the downstream elements like
videosink.

Allocate GValues on the stack, and unset/free them properly, fixing
a few leaks in the process. Also use gst_structure_take_value()
where appropriate to avoid unnecessary list copies.
Some version of basetransform will return the template caps if the src
pad is not linked, so the capsfilter will return ANY. Linking it to
fakesink allows us to return the right caps in the capsfilter and have
them transformed by the colorspace converter.
These override the variants without version suffix. Makes 'make check' work
properly in environments that set the suffixed variant for 1.0, such as
jhbuild.
Since commit c89b589a586e97ad875fbdd1d41f03979157ebb0, D-Bus >= 1.4.0 is
required. This version already contains Unix FD passing support,
therefore code that checks for DBUS_TYPE_UNIX_FD definition is
unnecessary.
In gst_avdtp_sink_start(), if bt_audio_service_open() failed, there was
an attempt to close an invalid file descriptor (through
bt_audio_service_close()).
Variables which are assigned to the errno variable (usually called
"err") should be negative, and "-err" should be used where a positive
value is needed.
The header files with constants and structures for audio specific
interaction with Pulseaudio are suppose to be under LGPL license.
For some odd reason a2dp-codecs.h ended up being under GPL license
which is against the intention of this being shared and re-used by
non-GPL programs. Fix this now to avoid any future confusion.
