ef24518b60 h264parse: optimize slice nal processing
Only minimal slice info is needed here to determine real frame start,
so no need to parse extensively.

Fixes #665418.

7fae33a661 h264parse: fix up AU collection processing
On the one hand, no need to collect nal if processing last one.
On the other hand, ensure AU collection processing to have sufficient
next NAL data in normal cases.

Fixes #663180.

9db239e1ec h264parse: some more get_caps tweaking

f3f9e4b978 h264parse: Implement ::sink_get_caps to allow stream-format conversion again
Just proxying the downstream caps will prevent h264parse from
accepting a different stream-format than what is supported
downstream, although it could convert to a different stream-format.

6a8d66728f h264parse: allow full negotiation for packetized input
... by defaulting to allow splitting packetized input and having
negotiation with downstream deciding whether or not this applies.

Also enable pass-through parsing mode if input and output format
(stream-format and alignment) match.

API: GstH264Parse:split-packetized (removed)

is less than expected 2 and discard it.

d0b942980e videoparsers: add h264parse
Functionally equivalent to (legacy)h264parse and re-uses the latter's low
level NAL parsing, but otherwise based on GstBaseParse, and replacing
some property configuration with caps negotiation.
