  h264_parser: switch to h2645_parse for NAL unescaping
Merged-by: Hendrik Leppkes <h.leppkes@gmail.com>

Some streams contain an additional AnnexB NAL inside the mp4/nalff NALU.
This commonly occurs in interlaced streams where both fields are packed
into the same MP4 NAL with an AnnexB startcode in between.

Port handling of this format from the previous h264 nal handling.

Fixes trac #5529

1. no longer use the register names directly and optimized code format
2. to be compatible with O32, specify type of address variable with mips_reg and handle the address variable with PTR_ operator
3. optimize some unaligned loads and stores
4. use uld and mtc1 to workaround cpu 3A2000 gslwlc1 bug (gslwlc1 instruction extension bug in O32 ABI)

larger than the value representing unity.
