[issue2101] make extension paths relative to hgrc location

[Russ Cox]

New submission from Russ Cox <rsc at swtch.com>:

I use hg extensions specific to certain repositories,
and I keep the extensions in the repository.
If I'm editing /home/rsc/repo/.hg/hgrc then it would
be convenient if

[extensions]
mything = unrooted/path

meant to look for the path relative to the repo root,
that is, in /home/rsc/repo/unrooted/path.

Similarly it would be convenient if in /home/rsc/.hgrc it
meant relative to my home directory, so /home/rsc/unrooted/path.

It would also be useful if I could refer to environment
variables or the repository path from inside the config,
so that even if this behavior didn't exist (I still think
it should), I could write

[extensions]
mything = %reporoot%/unrooted/path
otherguy = $HOME/unrooted/path
