convertbmp: detect invalid file dimensions early
...
width/length dimensions read from bmp headers are not necessarily
valid. For instance they may have been maliciously set to very large
values with the intention to cause DoS (large memory allocation, stack
overflow). In these cases we want to detect the invalid size as early
as possible.
This commit introduces a counter which verifies that the number of
written bytes corresponds to the advertized width/length.

jp2: convert: fix null pointer dereference

Tile components in a JP2 image might have null data pointer by defining a
zero component size (for example using large horizontal or vertical
sampling periods). This null data pointer leads to null image component
data pointer, causing crash when dereferenced without != null check in
imagetopnm.
Add != null check.

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
...
This check was introduced per #939 , but relied on the incorrect assumption
we decode all the tile parts of all tiles.

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

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

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

Make opj_set_decode_area() and opj_decode() take into account opj_set_decoded_resolution_factor() ( #1006 , affect API use)

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