overlayworkingctx: fix file/dir audit to be repo-relative

Before this patch, test-rebase-inmemory.t would stop erroring out
about the conflict if you added a "cd a" before line 252. That was
because a glob matcher (which are relative) was unintentionally
used. That happened because the matcher was given "include" patterns
(not regular patterns), and "include" patterns are always glob by
default (i.e. unless you write them including the kind prefix). IOW,
the "default='path'" argument passed to ctx.match() was ignored.

Helper function to run protocol tests against multiple protocol versions.
This is easier than using #testcases because managing differences between
protocols with inline conditional output is hard to read.

>=0.9.1 clients send a "hello" + "between" for the null range as part of handshake.
Server should reply with capabilities and should send "1\n\n" as a successful
reply with empty response to the "between".
