Support non-fastforward commits
This includes:
* adding a filter to accessctl which can be used to allow non-ff commits, and
augmenting the default access controls to deny non-ff commits for master.
VerifyCommits was then modified to use that new functionality, and then tests
were added to cover that.
* adding a `VerifyBranchCanSetHEADTo` method, and using that in the pre-receive
hook rather than putting all the logic in the hook itself.
`VerifyBranchCanSetHEADTo` is thoroughly tested, and the tests for it ended up
uncovering some broken aspects of `VerifyCommits` as well, so those are fixed
too.

completely refactor accessctl (again)
This time it's using an actual access control list system, rather than whatever
it was doing before. The new system uses a Filter type, rather than Condition,
to decide which acl element should have its action (allow or deny) applied. This
makes testing way easier, since all the different matching conditions are now
individual filters, and so are tested individually.
