lfs: add the ability to disable the usercache
While the usercache is important for real world uses, I've been tripped up more
than a couple of times by it in tests- thinking a file was being downloaded, but
it was simply linked from the local cache. The syntax for setting it is the
same as for setting a null remote endpoint, and like that endpoint, is left
undocumented.
This may or may not be a useful feature in the real world (I'd expect any sane
filesystem to support hardlinks at this point).

Testing head checking code: Case C-3
====================================
Mercurial checks for the introduction of new heads on push. Evolution comes
into play to detect if existing branches on the server are being replaced by
some of the new one we push.
This case is part of a series of tests checking this behavior.
Category C: case were the branch is only partially obsoleted
TestCase 3: 2 changeset branch, only the head is pruned
.. old-state:
..
.. * 2 changeset branch
..
.. new-state:
..
.. * old head is pruned
.. * 1 new unrelated branch
..
.. expected-result:
..
.. * push denied
