Pull in boost 1.81.0

Boost 1.81.0 has some very good changes for us, as it drops the
boost-url beta dependency, in leiu of standard boost.  Because it has
some breaking API changes, it seems like a good idea to get ahead of it,
and pull in the update a few weeks ahead of time.  Looking through the
changelogs, there's nothing in the modules that we use that would pose
any concern for us, aside from the boost-url changes, which is the point
of this commit.

This needs to go hand in hand with:
