codecparsers: h264: record number of emulation prevention bytes in
slice_header()

Some hardware video decode acceleration API (VA-API, DXVA) require a bit count
to the first macroblock, minus the number of emulation prevention bytes. So,
instead of having the consumer of the library scan the slice_header() again,
just record that number while parsing.
