This adds copyright/license notification blocks CMake's find-modules.
Many of the modules had no notices at all. Some had notices referring
to the BSD license already. This commit normalizes existing notices and
adds missing notices.

Qt3 and Qt4 cannot be used together in one project.
Now Qt3/KDE3 and Qt4/KDE4 handle the case that this is done nevertheless
properly, i.e. they fail with FATAL_ERROR if it was REQUIRED and they fail
with just MESSAGE(STATUS ...) and RETURN() if it was not REQUIRED
BUG: make FindQt4 error out with FATAL_ERROR also if it was searched QUIET

- The find_* commands now provide a HINTS option.
- The option specifies paths to be preferred over the system paths.
- Many Find* modules were using two find calls with NO_DEFAULT_PATH
to approximate the behavior, but that blocked users from overriding
things with CMAKE_PREFIX_PATH.
- This commit uses the HINTS feature to get desired behavior in
only one find command call.
