extensions: extract partial application into a bind() function
We use partial function application for wrapping existing Mercurial functions,
and it's implemented separately each time. This patch extracts the partial
application into a new bind() function that can be used on its own by extensions
when appropriate.
In particular, the evolve extension needs to wrap functions in the various
bundle2 processing dictionaries, which the pre-existing methods don't support.
