(redirect_handler): PROPFIND is defined to be "safe and
idempotent", so allow automatic redirects of it. (Pointed out by
Christian Kellner. FIXME: need a way for apps to declare
additional safe methods). Also, treat 302 like 307, not like 303,
because that behavior is universal in the real world, despite the
spec's protests.
* tests/redirect-test.c (tests): update POST 302 behavior check
* tests/Makefile.am (TESTS): oops, add redirect-test so it gets
run by "make check"/"make distcheck"
