This CL will start to distinguish H264 profiles during SDP negotiation. We currently don't look at the H264 profile at all and assume they are all Constrained Baseline Level 3.1. This CL will start to check profiles for equality when matching, and will generate the correct answer H264 level. Each local supported H264 profile needs to be listed explicitly in the list of local supported codecs, even if they are redundant. For example, Baseline profile should be listed explicitly even though another profile that is a superset of Baseline is also listed. The reason for this is to simplify the code and avoid profile intersection during matching. So VideoCodec::Matches will check for profile equality, and not check if one codec is a subset of the other. This also leads to the nice property that VideoCodec::Matches is symmetric, i.e. iif a.Matches(b) then b.Matches(a).
