Most users of ff_adts_header_parse() don't already have
an opened GetBitContext for the header, so add a convenience
function for them.
Also use a forward declaration of GetBitContext in adts_header.h
as this avoids (implicit) inclusion of get_bits.

The requirement is either 8 or 16 bytes alignment, not 32.
