vertical pass involves a lot of cache trashing.
With the bench_dwt utility with default arguments (16383x16383 image),
time goes from 4.064 s to 1.212 s.

Encoder: fix packet writing of empty sub-bands ( #891 , #892 )
...
There are situations where, given a tile size, at a resolution level,
there are sub-bands with x0==x1 or y0==y1, that consequently don't have any
valid codeblocks, but the other sub-bands may be non-empty.
Given that we recycle the memory from one tile to another one, those
ghost codeblocks might be non-0 and thus candidate for packet inclusion.

Create separate type for bit-fields.
...
The definition of bit-fields with type OPJ_UINT32 caused complilation errors
on IBM iSeries, because OPJ_UINT32 is defined as uint32_t, and
uint32_t is defined as unsigned long in <stdint.h>. The definition of
bit-fields with an integer type of a specific size doesn't make sense
anyway.

jpwl: Remove non-portable data type u_int16_t (fix issue #796 ) ( #797 )

The type casts which used this data type can be removed by changing
the signature of function swap16. As this function is called with
unsigned variables, this change is reasonable.

By default, only the main thread is used. If opj_codec_set_threads() is not used,
but the OPJ_NUM_THREADS environment variable is set, its value will be
used to initialize the number of threads. The value can be either an integer
number, or "ALL_CPUS". If OPJ_NUM_THREADS is set and this function is called,
this function will override the behaviour of the environment variable.
