tiffcrop: fix asan runtime error caused by integer promotion 
tiffcrop.c:4027:20: runtime error: left shift of 190 by 24 places cannot be represented in type 'int'

C treats (byte << 24) as an int expression.
casting explicitely to unsigned type uint32 avoids the problem.

the same issue has been fixed elsewhere with a242136916

I detected the bug with the test file of #86

9cfa5c4691 tiffcrop.c: fix invertImage() for bps 2 and 4 
too much bytes were processed, causing a heap buffer overrun
    http://bugzilla.maptools.org/show_bug.cgi?id=2831
the loop counter must be
    for (col = 0; col < width; col += 8 / bps)

Also the values were not properly calculated. It should be
255-x, 15-x, 3-x for bps 8, 4, 2.

But anyway it is easyer to invert all bits as 255-x = ~x, etc.
(substracting from a binary number composed of all 1 is like inverting
the bits)

tiff2ps: fix heap-buffer-overflow 
http://bugzilla.maptools.org/show_bug.cgi?id=2834

usually the test (i < byte_count) is OK because the byte_count is divisible by samplesperpixel.
But if that is not the case, (i + ncomps) < byte_count should be used, or
maybe (i + samplesperpixel) <= byte_count

473851d211 Fix for bug 2772 
It is possible to craft a TIFF document where the IFD list is circular,
leading to an infinite loop while traversing the chain. The libtiff
directory reader has a failsafe that will break out of this loop after
reading 65535 directory entries, but it will continue processing,
consuming time and resources to process what is essentially a bogus TIFF
document.

This change fixes the above behavior by breaking out of processing when
a TIFF document has >= 65535 directories and terminating with an error.
