9ecabd7892 h264: reset num_reorder_frames if it is invalid 
An invalid VUI is not considered a fatal error, so the SPS containing it
may still be used. Leaving an invalid value of num_reorder_frames there
can result in writing over the bounds of H264Context.delayed_pic.

7f0e81db3c h264: limit allowed pred modes in ff_h264_check_intra_pred_mode() to 3 
Higher modes are not allowed for 16x16/chroma, which is what this
function is used for. Otherwise this function would return 0 (vertical
prediction) for invalid higher modes, which could result in invalid
reads.

Several decoders disable those anyway and they are not measurably faster
on x86. They might be somewhat faster on other platforms due to missing
emu edge SIMD, but the gain is not large enough (and those decoders
relevant enough) to justify the added complexity.

5dae487235 arm: Allow overriding the alignment set in the function macro 
The function macro always sets .align 2 before declaring the
function label (since 5c5e1ea3) and always sets the section to
.text (since 278caa6a).

The .align 5 before certain functions, added in fc252eba, were added
before .text and .align were added to the function macro and thus
became useless/unused when the function macro got them.

This restores the original intention, to align the loop entry
points.
