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.

JBIG: fix potential out-of-bounds write in JBIGDecode() 
JBIGDecode doesn't check if the user provided buffer is large enough
to store the JBIG decoded image, which can potentially cause out-of-bounds
write in the buffer.
This issue was reported and analyzed by Thomas Dullien.

Also fixes a (harmless) potential use of uninitialized memory when
tif->tif_rawsize > tif->tif_rawcc

And in case libtiff is compiled with CHUNKY_STRIP_READ_SUPPORT, make sure
that whole strip data is provided to JBIGDecode()
