Summary:
Sharing repo.changelog across threads is problematic in mercurial
since it may internally cache things, and clearing cache while another
thread is executing is not nice. In particular, code such as the following
is inherently raceful when sharing changelogs (or anything derived from
revlog) across threads:
if self._cache:
if self._cache[0] == node:
return self._cache[2]
cachedrev = self._cache[1]
Reworked things a bit to make sure the spawned threads have their own
newly created changelogs and member functions internally referencing them.
Test Plan:
No longer seeing random exceptions being thrown from local log
threads (which terminates iteration)

Summary:
The multi-path support is pretty shameful; we can
do much better by issuing multiple queries and combining
results. File support was also missing.
Test Plan:
Ran fastlog test. Need to update test to test files.

Bugfix - we were failing to check local patterns in the fastpath.
Pass a filtering function to the local log thread to limit its results.

Summary:
When the restriction of only working on a single directory
was dropped, pattern support was neglected. That has to be done through
a revset, not the looser matches() filter.

Summary:
Parallel callout to scmquery through conduit
This implements the special case of log on a single directory, preserving
follow behavior. To do this, we backtrackfrom the current head to find
all draft revisions along the path, then find the common public ancestor of
those. Once we find that, we can begin paging in results from the scmquery
service.
Pretty much a working diff at this point. Limits and boundary conditions
have not been fully tested. Every once in a while I run into a bum query,
which I suspect to be either a bad proxy or a service router failure; still
debugging that. Could also be an issue with conduit. Other than that,
things seem to work.
Test Plan:
