hg: establish function for performing post-share actions
As part of writing an extension that wished to share an arbitrary piece
of data among shared repos, I had to reimplement a significant part of
hg.share in order to obtain localrepository instances for the source
and destination.
This patch establishes a function in hg.py that will be called after a
share is performed. It is passed localrepository instances so extensions
can easily perform additional actions at share time. We move hgrc and
shared file writing there because this function is a logical place for
it.
A side effect of the refactor is writing of the shared file now occurs
before updating. This seems more appropriate and shouldn't have any
impact on real world behavior.
