This avoids a potential conflict with the equally named function for closing files
It also could reduce confusion in debugger backtraces

Quite a few programs missed that detail of the spec
(including old versions of FFmpeg I believe) and when
we would otherwise fail anyway it seems worth a try
to use a simple byte-aligned stride instead.

It does not work correctly and apparently never did. There is no
indication that this (mis)feature is ever used in the wild or even that
any software other than the reference supports it.
Since the code that attempts to support it adds some nontrivial
complexity and has resulted in several bugs in the past, it is better to
just drop it.
Currently, it needs to be initialized by the ER caller (which is
currently either a mpegvideo decoder or h264dec). However, since none of
those decoders use MECmpContext for anything except ER, it makes more
sense to handle it purely inside ER.
This should behave similar to x264 and other encoders, as it handles a
gop_size of 0 as Intra-Only, while it's still possible to control how
many B-Frames it inserts.

if the openjpeg parameter tcp_rates is not 0 ( using the ffmpeg compression_level option )
every 2nd image per thread is badly encoded. By moving the opj_setup_encoder function from
libopenjpeg_encode_init to libopenjpeg_encode_frame this can be prevented.
This fixes ticket #3754.

This improves motion estimation and avoids using uninitialized data
for resolutions that aren't a multiple of 16.
Prior to d2a25c40, the edges used to be initialized so that encoding
was deterministic, but after that commit it started using uninitialized
data (for non multiple of 16 resolutions).

This like the previous attempt does not fully correctly decode this
type of non standard H.264, but it now works fully automatic
requiring no manual filters or flags to be used
