h264parse: parse SPS subset

Browse source 
This patch calls gst_h264_parser_parse_subset_sps() when a
SPS subset NAL type is found.

All the bits required for parsing the SPS subset in NALs were
already there, just we need to call them when the this NAL type
is found.

With this parsing, the number of views (minus 1) attribute is
filled, which was a requirement for negotiating the stereo-high
profile.
