push: elevate phase transaction to cover entire operation

This patch series is intended to allow bundle2 push reply part handlers to
make changes to the local repository; it has been developed in parallel with
an extension that allows the server to rebase incoming changesets while applying
them.

Most pushes already open a transaction in order to sync phase information.
This diff replaces that transaction with one that spans the entire push
operation.

This transaction will be used in a later patch to guard repository changes
made during the reply handler.
