Summary:
Simplifies some shell code, namely `$extpath` is duplicated with `$TESTDIR/..`
so remove one of them.
Change `library.sh` (used by remotefilelog tests) to reuse `$HGRCPATH` instead
of overriding the environment variable, because it never gets restored and the
current code would assume `$HGRCPATH` to have `.hgrc` as its basename, which is
not always true.
Test Plan: `arc unit`

Summary:
Previously we can only answer the "path" information when the revision is in
the linelog revmap, and the code would crash if a revision is in a side
branch, and the user requests path information. This diff fixes it.
Besides, this diff improves rename handling. For example, given the following
chart:
```
o---o -o file name: a
/
o---o- file name: b
^ ^ ^
1 2 3 revisions
```
Depending on the position of the `main branch` reference, fastannotate may
or may not use linelog:
- main branch is at rev 2, annotate a -r 3 will not take advantage of linelog
(fallback to slow annotate)
- main branch is at rev 3, annotate a -r 2 will not take advantage of linelog
This is not ideal, but seems to be the best we can do for now.
Test Plan:
Added a new test, updated existing relevant tests. Some debug messages are
changed to reflect internals more precisely.
