Robert Haas bbb6e559c4 Make VACUUM avoid waiting for a cleanup lock, where possible.

In a regular VACUUM, it's OK to skip pages for which a cleanup lock
isn't immediately available; the next VACUUM will deal with them.  If
we're scanning the entire relation to advance relfrozenxid, we might
need to wait, but only if there are tuples on the page that actually
require freezing.  These changes should greatly reduce the incidence
of of vacuum processes getting "stuck".
