dfaf2dd956 h264: use externally provided dimensions when they appear to be more correct.
This is based on:
	commit 30f515091c
	Author: Mans Rullgard <mans@mansr.com>
    		h264: allow cropping to AVCodecContext.width/height

The above commit is not taken as is as its buggy (incorrect handling of
the interlaced case) and didnt apply cleanly.

Fixes ticket156

30f515091c h264: allow cropping to AVCodecContext.width/height
Override the frame size from the SPS with AVCodecContext values
if the latter specify a size smaller by less than one macroblock.
This is required for correct cropping of MOV files from Canon cameras.

b7d1488393 h264: move q0 scan tables into context
This fixes out of global array reads.
The alternative solutions of checking the index or modifying the VLC tables
to prevent the index going outside are each about 1-2 cpu cyclces slower
per coded 4x4 block.
The alternative of padding the global tables directly is more ugly and
moving them to the context should benefit cache locality.

1e26a48fa2 h264: fix deadlocks on incomplete reference frame decoding.
If decoding a second complementary field, and the first was
decoded in our thread, mark decoding of that field as complete.
If decoding fails, mark the decoded field/frame as complete.
Do not allow switching between field modes or field/frame mode
between slices within the same field/frame. Ensure that two
subsequent fields cover top/bottom (rather than top/frame,
bottom/frame or such nonsense situations).

Fixes various deadlocks when decoding samples with errors in
reference frames.

45b7bd7c53 h264: disallow constrained intra prediction modes for luma.
Conversion of the luma intra prediction mode to one of the constrained
("alzheimer") ones can happen by crafting special bitstreams, causing
a crash because we'll call a NULL function pointer for 16x16 block intra
prediction, since constrained intra prediction functions are only
implemented for chroma (8x8 blocks).
