outgoing: remove some early return Since 066b8d8f75b8, the push command accept multiple destination. However `hg outgoing` does not. On the way to fix this, we need to clean up the outgoing code. We start with removing some early return to make the code ready to house more changes. Differential Revision: https://phab.mercurial-scm.org/D10380

infinitepush: use the new function to determine push destination Since 066b8d8f75b8, the push command accept multiple destination. `infinitepush` was not aware of that. We now use the new `urlutil.get_push_paths` function to determine the push destination, fixing the issue. This will also make future evolution of that logic transparent for infinitepush We still disallow push to multiple destinations if infinite push is enabled because I don't know what this means for infinite push. However user will now get a clear error message instead of a crash. Differential Revision: https://phab.mercurial-scm.org/D10379

urlutil: add a `get_pull_paths` to perform the pull destination logic As is this changeset does not change anything. However having an official empty point will help unifying the logic and encapsulate the details and update the logic to support path definition pointing to multiple other path.
