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.

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.

openjp2: Error out if failing to create Tier 1 handle.
...
Previously when the handle failed to be created (e.g. when
opj_calloc returned NULL due to low memory), the code still
assumed that the t1 handle pointer was valid and dereferenced
NULL, causing a crash. After this commit OpenJPEG will instead
error out under this condition.
This fixes issue #1255 .
