commands.push: use paths API
ui.path instances now collect most of the data used by commands.push().
Move away from ui.expandpath() and call ui.paths.getpath() to get a
path instance.
Some "pushing to" output was dropped as one test demonstrates. I believe
the dropped message was redundant with the error message and the change
to be acceptable.
$ hg init a
$ echo a > a/a
$ hg --cwd a ci -Ama

$ hg clone a b

Push should provide a hint when both 'default' and 'default-push' not set:
$ cd c
$ hg push --config paths.default=
abort: default repository not configured!
(see the "path" section in "hg help config")
