rcutil: add a method to convert environment variables to config items

Handling config and environ priorities has been messy. Partially because we
don't have config layers - you either get all configs (sys + user), or none.

Ideally, environ like $EDITOR, $PAGER should be able to override the system
configs "ui.editor", "pager.pager". This patch provides the ability to
convert them into config items, so they can be inserted into the middle
config layer between system rc and user rc.

#require test-repo pylint hg10

Run pylint for known rules we care about.
-----------------------------------------

There should be no recorded failures; fix the codebase before introducing a
new check.

Current checks:
- W0102: no mutable default argument
