a05006944a codecparsers: GST_EXPORT -> GST_CODEC_PARSERS_API
We need different export decorators for the different libs.
For now no actual change though, just rename before the release,
and add prelude headers to define the new decorator to GST_EXPORT.

de327bf45b vc1parser: fix level values for simple/main profile
In simple profile, level set to 0 or 2 indicate low and medium level
respectively. In main profile, level set to 0, 2 or 4 indicate low,
medium and high level respectively.

Level values are defined in Annex J.1.2 of the SMPTE 421M.

07a51b16eb codecparsers: vc1: add API to parse slice headers.
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.

cbec9bfcd0 codecparsers: vc1: simplify GstVC1VopDquant structure.
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.

fc09e45108 codecparsers: VC1: Implement Sequence Layer Data Structures
Instead of having a single VC1SequenceHeader structure, use the 3 structs
from the "Table 265: Sequence Layer Data Structure" of the specification
for the library to be more flexible.
