147 Fix 2.2.0 regression when reading codestream with reperated calls to opj_get_decoded_tile() where tile parts of a same tile are not consecutive

150 we decode all the tile parts of all tiles.

162 Add knownfailures-Ubuntu12.04-gcc4.6.3-x86_64-Release-3rdP.txt
164 For some reason, the OPJ_CI_ARCH=x86_64 OPJ_CI_BUILD_CONFIGURATION=Release OPJ_NUM_THREADS=2
165 configuration fails once PR1010 has been merged in master
166 ( https://travis-ci.org/uclouvain/openjpeg/jobs/272219011 ) whereas (almost) the same
167 code in my branch didn't fail per https://travis-ci.org/rouault/openjpeg/jobs/271738113
169 The errors we get are the same as with the other x86_64 compilers, so nothing alarming here.

330 Allow several repeated calls to opj_set_decode_area() and opj_decode() for single-tiled images
332 * Only works for single-tiled images --> will error out cleanly, as currently
334 * Save re-reading the codestream for the tile, and re-use code-blocks of the
335 previous decoding pass.
336 * Future improvements might involve improving opj_decompress, and the image writing logic,
337 to use this strategy.

349 Various changes to allow tile buffers of more than 4giga pixels
351 Untested though, since that means a tile buffer of at least 16 GB. So
352 there might be places where uint32 overflow on multiplication still occur...

372 However the intermediate buffer for decoding must still be smaller than 4
373 billion pixels, so this is useful for decoding at a lower resolution level,

392 Sub-tile decoding: only allocate tile component buffer of the needed dimension
394 Instead of being the full tile size.
396 * Use a sparse array mechanism to store code-blocks and intermediate stages of
398 * IDWT, DC level shift and MCT stages are done just on that smaller array.
399 * Improve copy of tile component array to final image, by saving an intermediate
401 * For full-tile decoding at reduced resolution, only allocate the tile buffer to
402 the reduced size, instead of the full-resolution size.

432 Make opj_set_decode_area() and opj_decode() take into account opj_set_decoded_resolution_factor() (#1006, affect API use)
434 * Better document usage of opj_set_decode_area(), ie expecting coordinates
435 in full resolution/reference grid even if requesting at a lower resolution
437 * Make sure that image->comps[].factor is set by opj_set_decode_area() and
438 opj_decode() from the value specified in opj_set_decoded_resolution_factor()
439 * opj_decompress: add 2 environmenet variables to test alternate ways of
440 using the API, namely USE_OPJ_SET_DECODED_RESOLUTION_FACTOR=YES to use
441 opj_set_decoded_resolution_factor() instead of parameters.cp_reduce, and
442 SKIP_OPJ_SET_DECODE_AREA=YES to not call opj_set_decode_area() if -d is
