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)

TIFFWriteDirectoryTagTransferfunction() : fix NULL dereferencing

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

d0a842c5db tif_dir: unset transferfunction field if necessary 
The number of entries in the transfer table is determined as following:

(td->td_samplesperpixel - td->td_extrasamples) > 1 ? 3 : 1

This means that whenever td->td_samplesperpixel or td->td_extrasamples are
modified we also need to make sure that the number of required entries in
the transfer table didn't change.

If it changed and the number of entries is higher than before we should
invalidate the transfer table field and free previously allocated values.
In the other case there's nothing to do, additional tf entries won't harm
and properly written code will just ignore them since spp - es < 1.

For instance this situation might happen when reading an OJPEG compressed
image with missing SamplesPerPixel tag. In this case the SamplesPerPixel
field might be updated after setting the transfer table.

see http://bugzilla.maptools.org/show_bug.cgi?id=2500

This commit addresses CVE-2018-19210.
