Hugo Lefeuvre 0bc90e4062 jp3d/jpwl convert: fix write stack buffer overflow
Missing buffer length formatter in fscanf call might lead to write
stack buffer overflow.

opj_mj2_extract: Check provided output prefix for length
This uses snprintf() with correct buffer length instead of sprintf(), which
prevents a buffer overflow when providing a long output prefix. Furthermore
the program exits with an error when the provided output prefix is too long.

Fixes #1088.

Hugo Lefeuvre ca16fe5501 convertbmp: fix issues with zero bitmasks
In the case where a BMP file declares compression 3 (BI_BITFIELDS)
with header size <= 56, all bitmask values keep their initialization
value 0. This may lead to various undefined behavior later e.g. when
doing 1 << (l_comp->prec - 1).

This issue does not affect files with bit count 16 because of a check
added in 16240e2 which sets default values to the color masks if they
are all 0.

This commit adds similar checks for the 32 bit case.

Also, if a BMP file declares compression 3 with header size >= 56 and
intentional 0 bitmasks, the same issue will be triggered in both the
16 and 32 bit count case.

This commit adds checks to bmp_read_info_header() rejecting BMP files
with "intentional" 0 bitmasks. These checks might be removed in the
future when proper handling of zero bitmasks will be available in
openjpeg2.

Stefan Weil 4aaf52ec8d Use local type declaration for POSIX standard type only for MS compiler
ssize_t is a POSIX type which is declared in POSIX include files.
Mingw-w64 provides it also for Windows.

Use the local declaration only with MS compilers.
