Changed all tiff devices to use libtiff.

Affected Devices are tiffgray, tiff12nc, tiff24nc, tiff32nc, tiffsep, tiffsep1,
tiffcrle, tiffg3, tiffg32d, tiffg4, tifflzw, and tiffpack.  Also, two new
devices: tiff48nc and tiff64nc (16 bits per component rgb and cmyk respectively)
have been added.

Libtiff 3.9.2 is included in the source tree as tiff/.  It is possible to link
to the system's libtiff by passing --with-system-libtiff to configure.  Passing
--without-system-libtiff will force the build to use the in-source version. By
default, the newer library (based on TIFFLIB_VERSION in tiffvers.h) is used.

Expected Differences:
Internal file structure of the resulting TIFF files differs from the previous
devices: the tag directory is now at the end of each page and the tags might be
in a different order.  However, the semantics of the files as well as the image
data are the same.

One notable exception is the Group3Options tag, which was wrongly inserted into
tiffpack, tiffcrle, and tifflzw compressed files before.
