testing: add file storage integration for bad hashes and censoring
In order to implement these tests, we need a backdoor to write data
into storage backends while bypassing normal checks. We invent a
callable to do that.
As part of writing the tests, I found a bug with censorrevision()
pretty quickly! After calling censorrevision(), attempting to
access revision data for an affected node raises a cryptic error
related to malformed compression. This appears to be due to the
revlog not adjusting delta chains as part of censoring.
I also found a bug with regards to hash verification and revision
fulltext caching. Essentially, we cache the fulltext before hash
verification. If we look up the fulltext after a failed hash
verification, we don't get a hash verification exception. Furthermore,
the behavior of revision(raw=True) can be inconsistent depending on
the order of operations.
I'll be fixing both these bugs in subsequent commits.

==================================== Testing head checking code: Case D-1 ==================================== 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 D: remote head is "obs-affected" locally, but result is not part of the push TestCase 1: remote head is rewritten, but successors is not part of the push .. old-state: .. .. * 1 changeset branch .. .. new-state: .. .. * 1 changeset branch succeeding the old branch .. * 1 new unrelated branch .. .. expected-result: .. .. * pushing only the unrelated branch: denied .. .. graph-summary: .. ..
