libav: avcodec_close() also resets fields like the AVCodec

We need to reload the defaults for the codec after closing it,
otherwise we can't access codec information like the supported
sample rates and can crash.

avcodecmap: exclude avc3 stream format from AV_CODEC_ID_H264

As part of the changes to support the "avc3" variant of the ISO-BMFF
(see bug #702004) a new stream-format has been created
(video/x-h264, stream-format="avc3", alignment="au") that requires
changes to gstavcodecmap to exclude this format because avdec_h264
expects the SPS and PPS to be in the codec_data.

Amendment 2 of ISO/IEC 14496-15 (AVC file format) is defining a new
structure for fragmented MP4 called "avc3". The principal difference
between AVC1 and AVC3 is the location of the codec initialisation data
(e.g. SPS, PPS). In AVC1 this data is placed in the initial MOOV box
(moov.trak.mdia.minf.stbl.stsd.avc1) but in AVC3 this data goes in the
first sample of every fragment.

libav does not allow stride changes currently, fall back to
non-direct rendering here:

avviddec: Use the correct context for negotiation

During get_buffer() it can happen that the main context is not
updated yet and only the context passed here has the correct
width, height, etc.
libav: Update to v9.9
avviddec: Initialize strides with the ones of avcodec_default_get_buffer() if we ever call it
