test-lfs: add tests covering http exchanges
This tries to test every combination of having the extension enabled/disabled
on each side, and then push/pull/clone/identify lfs and non-lfs content. SSH is
ignored here, because there's enough going on as it is.
The root issue here is again that requirements are not exchanged and preserved
on push/pull/clone. Doing so should eliminate the cryptic error messages when
using `hg serve`. The 500 server error is triggered by "ValueError: no common
changegroup version", because the extension forces changegroup3. Or, if
changegroup3 is enabled manually, it is triggered by "abort: missing processor
for flag '0x2000'!".
Sadly, run-tests.py doesn't support conditionalizing the exit code like it does
lines of output. Therefore, a couple of tests blot out the exit code by
appending "|| true", since these failures will go away shortly anyway.
