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.

1f3b4ad574 h264parse: remove redundant code

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 
... by having it use sink template rather than src template, and not
passing an downstream parsed(=true) to upstream.

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.

9c221f492d h264parse: properly interpret baseparse draining state

7bcc0c71b8 h264parse: ignore codec_data if stream-format=byte-stream 
Some encoders set codec_data even when outputting byte-stream. Before this patch
h264parse would incorrectly detect such streams as AVC.

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)

409a51bcea h264parse: gracefully handle truncated input NAL units 
Rather than assert'ing in such case, emit warning if the length of a NAL unit
is less than expected 2 and discard it.

d0b942980e videoparsers: add h264parse

level NAL parsing, but otherwise based on GstBaseParse, and replacing
some property configuration with caps negotiation.
