Add support for enabling generation of TLM markers in encoder
...
Support was already there, but restricted to Cinema and IMF profiles,
and 255 tiles
* Add -TLM switch added to opj_compress
* Make opj_encoder_set_extra_options() function accept a TLM=YES option.

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 .

Irreversible compression/decompression DWT: use 1/K constant as per standard
...
The previous constant opj_c13318 was mysteriously equal to 2/K , and in
the DWT, we had to divide K and opj_c13318 by 2... The issue was that the
band->stepsize computation in tcd.c didn't take into account the log2gain of
the band.
The effect of this change is expected to be mostly equivalent to the previous
situation, except some difference in rounding. But it leads to a dramatic
reduction of the mean square error and peak error in the irreversible encoding
of issue141.tif !
