CMakeLists.txt and .cmake files of significant size
(more than 2 lines according to our check in tst_license.pl)
now have the copyright and license header.
Existing copyright statements remain intact

If, for whatever reason, BOOST_NO_EXCEPTIONS is defined, the user of
the Boost libraries is supposed to provide a definition of
boost::throw_exception, which we didn't.
We used to run into this only on ubsan builds, but it seems we now
have the problem on a regular Ubuntu 22.04 build, too (cf. bugreport).
Fix by adding the necessary definitions.
Fixes: QTBUG-104083
Pick-to: 6.4 6.3

Initial results with GCC:
Even though GCC's assembly looks rather bad because of the implicit
fall-back from atomics to non-atomics for single-threaded
applications, libstdc++'s shared_ptr still performs twice as fast as
QSharedPointer, proving that the branch predictor eats libstdc++'s
is-multi-threaded-check for breakfast and the two atomic operations of
a QSharedPointer copy vs. one for std::shared_ptr dominate the
run-time.
