Some streams do not include any IDR frames. However, they do include SEI recovery point markers. We use those to mark keyframes.

We have a minimum requirement of VS 2015 for Windows builds, which supports
the z length modifier for format specifiers. So we don't need SizePrintfMacros.h
any more, and can just use %zu and friends directly everywhere.

We dynamically allocate the memory we need and abort if OOM.

We detect when a PSSH is contained in a MOOF and stash them in the
mp4_demmuxer::Moof object. When the mp4_demuxer::SampleIterator returns a
sample, we check whether it's the first sample from its MOOF, and if so, we
attach any PSSH boxes from that MOOF to the sample. The TrackBuffersManager
checks samples upon demux, to see whether they have any EME init data attached,
and if so dispatches thoses to the HTMLMediaElement in 'encrypted' events.

They can change from one SPS to the next, causing unecessary reconstruction of the decoder.

We now compare the decoded data rather than the raw data, otherwise as seen in video from bug 1372766, we keep draining the decoder. For some reasons the SPS NALs only differ by 1 byte at a time.

All decoders appear capable of handling content change when just new PPS appears.
So we restrict the test to SPS changes.

With some H264 streams, we find that the SPS/PPS NALs are duplicated on the stream. This caused us to treat it as if the content changed due to the discrepency between the extradata found in the MP4 metadata and what found inband.
When scanning for SPS NALs, we now attempt to detect duplicates, and if so ignore them.

HasSPS, ExtractExtraData and CompareExtraData have nothing to do with the handling of annex B format. They are raw H264 related methods.
It will also prevent in the following change to have cycling references between two headers.
