The plugin export mechanism has been patched up (including the addition
of the JSON file), and the FindWebP.cmake file is new.
Writing is currently disabled, as it produces broken images.
Autotests are generated using the cwebp and dwebp utilities distributed
with the libwebp reference library.

The BSD license goes in the relevant CMake file, and
COPYING-CMAKE-SCRIPTS is removed. README.md gets a License section
describing the overall license of the framework, as well as a note about
the CMake scripts.
As part of this commit, I release the existing autotest images (which I
created myself) as public domain (or license them under CC0 where public
domain does not apply), ensuring they are compatible with whatever
license the package is distributed under.

src/imageformats/CMakeLists.txt is now much clearer and more consistent.
Also, removed an unnecessary/unimplemented method from exr.cpp.
