Summary: The goal of the whole series is to have logging around linknode fixup. It's a slow operation, and we have two heuristics to make it faster. Unfortunately we have no idea about how well these heuristics actually help. This series of diffs aims to fix this problem. After this series is landed and logging is enabled, I hope that we can find out if we really these heuristics at all.
Test Plan: Run test-remotefilelog-linknodes.t

Let's log more data to make it easier to analyze where and how often does
linknode adjusing happen.

Summary:
The _adjustlinknode function in remotefilectx currently has a slow case where
it must prefetch history from the server to lookup the correct linkcode.
This change makes use of fastlog (if enabled for the repo) to speed up the
linknode lookup as fastlog will already have the correct linkrev. If fastlog
is not enabled or the fastlog call fails for some reason then it will fall
back to the old method.
Test Plan: Added new test cases in test-remotefilelog-linknodes.t

When remotefilelog moved from its own repo, the tests needed to be updated to
adjust the PYTHONPATH to ensure the in-repo remotefilelog was loaded instead of
the system one.
This meant any local runs of remotefilelog tests would've been using the system
remotefilelog unless the user had manually set the PYTHONPATH themselves.
Summary:
See comment in code for details. This addresses a performance
problem that arises when the same remotefilelog repo makes two changes
to a file far apart in history with no other repo making changes to the
same file in between.
Test Plan: new test verifies that linkrevs are fixed up using remote blob

Summary:
This makes it possible to run all remotefilelog tests without others
It also avoids some issues with name collisions in the upcoming merge.
Test Plan: next commit is a merge and no conflicts in tests/
