opj_encoder_set_extra_options(): add a GUARD_BITS=value option
and add a -GuardBits option to opj_compress.

The recently-released SMPTE DCP Bv2.1 Application Profile (link below)
says that the number of guard bits in the QCD marker shall be 1 for 2K
content and 2 for 4K content. This change allows the number of guard bits
to be configured, so that users of openjpeg have the control they need to meet the specification.

This is an alternative implementation of https://github.com/uclouvain/openjpeg/pull/1388
that keeps ABI unchanged.

API: deprecate 'bpp' member in favor of 'prec'
in opj_image_comp and opj_image_comptparm structures.

bpp was redundant with prec, and almost never set by the library, except
by opj_image_create(). This change should hopefully not impact existing,
working, users of the API, which should already have used prec to get
things working.

Fixes #1379

Added support for high throughput (HTJ2K) decoding.
There are a few limitations:
- mixed mode (HT and regular code blocks) is not supported.
- ROI in HT blocks is not supported.
- Placeholder passes are not supported.
- MultiHT sets are not support, only a singleHT set.
- there are known issues with some compliance testing files related to
  the parsing of packet header.

Sebastian Rasmussen e0993d072a opj_j2k_is_imf_compliant: Fix out of bounds access.
Previously when mainlevel was parsed == 12 openjpeg would generate
a warning, but then the sublevel value would be compared to an out
of bounds element in the tabMaxSubLevelFromMainLevel array. From
this commit OpenJPEG will only use mainlevel if in range.

Testing with a Sentinel2 10m band, T36JTT_20160914T074612_B02.jp2,
coming from S2A_MSIL1C_20160914T074612_N0204_R135_T36JTT_20160914T081456.SAFE

Decompress it to TIFF:
```
opj_uncompress -i T36JTT_20160914T074612_B02.jp2 -o T36JTT_20160914T074612_B02.tif
```

Recompress it with similar parameters as original:
```
opj_compress -n 5 -c [256,256],[256,256],[256,256],[256,256],[256,256] -t 1024,1024 -PLT -i T36JTT_20160914T074612_B02.tif -o T36JTT_20160914T074612_B02_PLT.jp2
```

Dump codestream detail with GDAL dump_jp2.py utility (https://github.com/OSGeo/gdal/blob/master/gdal/swig/python/samples/dump_jp2.py)
```
python dump_jp2.py T36JTT_20160914T074612_B02.jp2 > /tmp/dump_sentinel2_ori.txt
python dump_jp2.py T36JTT_20160914T074612_B02_PLT.jp2 > /tmp/dump_sentinel2_openjpeg_plt.txt
```

The diff between both show very similar structure, and identical number of packets in PLT markers

Now testing with Kakadu (KDU803_Demo_Apps_for_Linux-x86-64_200210)

Full file decompression:
```
kdu_expand -i T36JTT_20160914T074612_B02_PLT.jp2 -o tmp.tif

Consumed 121 tile-part(s) from a total of 121 tile(s).
Consumed 80,318,806 codestream bytes (excluding any file format) = 5.329697
bits/pel.
Processed using the multi-threaded environment, with
    8 parallel threads of execution
```

Partial decompresson (presumably using PLT markers):
```
kdu_expand -i T36JTT_20160914T074612_B02.jp2 -o tmp.pgm -region "{0.5,0.5},{0.01,0.01}"
kdu_expand -i T36JTT_20160914T074612_B02_PLT.jp2 -o tmp2.pgm  -region "{0.5,0.5},{0.01,0.01}"
diff tmp.pgm tmp2.pgm && echo "same !"

Sebastian Rasmussen f3ee448815 openjp2/j2k: Validate all SGcod/SPcod/SPcoc parameter values.
Previously the multiple component transformation SGcod(C)
and wavelet transformation SPcod(H)/SPcoc(E) parameter
values were never checked, allowing for out of range values.

The lack of validation allowed the bit stream provided in
issue #1158 through. After this commit an error message
points to the marker segments' parameters as being out of
range.

input/nonregression/edf_c2_20.jp2 contains an SPcod(H) value
of 17, but according to Table A-20 of the specification only
values 0 and 1 are valid. input/nonregression/issue826.jp2
contains a SGcod(B) value of 2, but according to Table A-17
of the specification only values 0 and 1 are valid.
input/nonregression/oss-fuzz2785.jp2 contains a SGcod(B)
value of 32, but it is likewise limited to 0 or 1. These test
cases have been updated to consistently fail to parse the
headers since they contain out of bounds values.

This fixes issue #1210.

Sebastian Rasmussen b2751967ec openjp2/j2k: Report error if all wanted components are not decoded.
Previously the caller had to check whether each component data had
been decoded. This means duplicating the checking in every user of
openjpeg which is unnecessary. If the caller wantes to decode all
or a set of, or a specific component then openjpeg ought to error
out if it was unable to do so.

Fixes #1158.
