improve defaults
1. limit to single layer, as there is no current support for setting distortion/quality of multiple layers
2. encoder mode should be kept at default setting (0)
3. remove fixed_alloc parameter from context : seldom if ever used, and no way of properly configuring at the moment
4. add irreversible setting, to allow for lossless encoding. Set to OpenJPEG default (enabled)
5. set numresolution max to 33, which is the maximum number of allowed resolutions according the J2K spec

The calculation of width/height should round up, not round down to
prevent setting width or height to 0.
Also image->comps[compno].w is unsigned (at least in openjpeg2), so the
calculation could silently wrap around without the explicit cast to int.

openjpeg 2 sets the data pointers of the image components to NULL,
causing segfaults if the image is reused.

Use check_lib2 to test the header together with the function. This is
necessary, because '-DOPJ_STATIC' changes what the included header does.
Also add '-DOPJ_STATIC' to CPPFLAGS, so that it isn't necessary to
hardcode this in libavcodec/libopenjpeg{dec,enc}.c.
Finally, check for non-static openjpeg 2.1, too.

Allocating coded_frame is what most encoders do anyway, so it makes
sense to always allocate and free it in a single place. Moreover a lot
of encoders freed the frame with av_freep() instead of the correct API
av_frame_free().
This bring uniformity to encoder behaviour and prevents applications
from erroneusly accessing this field when not allocated. Additionally
this helps isolating encoders that export information with coded_frame,
and heavily simplifies its deprecation.

opj_set_event_mgr to libopenjpeg_encode_frame
libopenjpegenc crashes with "pointer being freed was not allocated" when threading

ffmpeg -i tests/vsynth1/01.pgm -vcodec libopenjpeg file.j2k

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.

The rationale is that you have a packed format in form
<greyscale sample> <alpha sample> <greyscale sample> <alpha sample>
and shortening greyscale to 'G' might make one thing about Greenscale instead.
An alias pixel format and color space name are provided for compatibility.
