7dc03df3de Improve and fix LATENCY query handling 
This now follows the design docs everywhere, especially the maximum latency
handling.

5dd1a28906 x264enc: Don't set max latency to the same value as the encoder latency 
The meaning of the max latency is *not* the maximum latency this element will
introduce. It is the maximum latency this element can endure without
overflowing any buffers, which is infinite for x264enc.

Fixes latency configuration in zero latency mode, where max latency was
becoming 0... which usually won't work well if something else introduces
latency as then max < min in the end, and latency configuration just fails.

5f075f3361 x264enc: set annexb=1 in byte stream mode when downstream has ANY caps 
This matches what is done when downstream caps are not ANY, and fixes
prerolling in byte stream mode when typefind is downstream.

acc9529a36 x264enc: Don't set an allocation maximum 
There is no reason x264enc should enforce a maximum allocation size.
The maximum is normally set by buffer pool which cannot grow, but we
don't offer a buffer pool. This would lead to stall when used with
element that don't implement allocation query.

698714fc97 x264enc: Shift both PTS and DTS to ensure positive timestamp 
Currently we only shift DTS to compensate that we don't support negative
timestamp. This cause a problem that PTS is no longer >= DTS and may
make muxers live much harder. Instead, shift both PTS/DTS forward. Also
remove all the hack to handle this which seems the result of thinking libx264
is bugged.

Flushing might happen before caps were set on the encoder,
which would lead to crashes here.

767005d8c0 x264: Fix dts comparision 
We were assigning to a guint64 value (frame->dts) the sum of a unsigned

Instead just check if it is smaller before assigning to frame->dts.

201e3f74be x264enc: put all theoretically possible formats in template caps 
and decide at runtime which subset of these (8-bit or 10-bit video
formats) is supported. libx264 will be compiled for one of these
two options, and it is possible to switch by pointing the dynamic
linker to a different libx264 build at runtime. If we want our
template caps to be correct, they should contain all then, with
the actually supported ones determined at runtime.
