Upgrading libtiff: Adding clean copy of libtiff 4.0.3
This commit removes the previous version of the bundled libtiff
(3.9.2), as well as all local modifications to it. It adds an
unmodified copy of the official libtiff source distribution, except
that various extraneous files have been removed, as usual.
The patches required to build it in Qt will follow in separate
commit(s).
