narrow: don't hexify paths and double-hexify known nodes on wire (BC)

It isn't obvious, but wireprototypes.encodelist() is meant only for
binary nodeids. So when we used it for encoding hex nodeids and paths,
the encoded result was surprising and hard to read.

This patch changes the encoding to make the list of paths a
comma-separated list and the list of common nodes to be a
encodelist()-encoded list of binary nodeids (so the result is just
singly-hexified nodeids).

This is clearly a breaking change, but the feature is experimental and
we're not aware of anyone running a server using this command yet.

== New Features ==

 * The amend extension supports the `--currentuser` argument.

 * The amend extension supports the `--close-branch` argument.

 * The amend extension supports the `--secret` argument.

 * The uncommit extension supports the `rewrite.update-timestamp` config option.

== New Experimental Features ==


== Bug Fixes  ==


== Backwards Compatibility Changes ==

 * A shell that supports `$(command)`` syntax for command substitution is now
   required for running the test suite. The test runner normally uses
   `sh`, so if that is a shell that doesn't support `$(command)` syntax,
   you can override it by setting `$HGTEST_SHELL` or by passing it to
   `run-tests.py --shell <shell>`.

 * The (experimental) narrow extension's wire protocol changed. If
   you're using it, you'll need to make sure to upgrade server and
   client at the same time.

== Internal API Changes ==
