debugdiscovery: use `get_unique_pull_path` Lets move this code to the new API. Differential Revision: https://phab.mercurial-scm.org/D10426

profiling: use `util.expandpath` instead of `ui.expandpath` for output Given we are talking about the path to an output file, I am fairly certain that the initial author meant to expand `~` and the like and not to resolve entry from `[paths]`. Differential Revision: https://phab.mercurial-scm.org/D10425

dispatch: use the new API to resolve --repository An even weirder feature of Mercurial is the ability to use `[paths]` alias as value of `--repository`. The weird feature now use the new APIs. Differential Revision: https://phab.mercurial-scm.org/D10424

revset: use `get_unique_pull_path` for `remote(…)` This one is also resolving path. For now we restrict the feature to a single destination. This might change in the future. Differential Revision: https://phab.mercurial-scm.org/D10422

remotefilelog: use `get_unique_pull_path` in `getflogheads` Another command moved to the new API, hooray. Differential Revision: https://phab.mercurial-scm.org/D10421

summary: use the new APIs Summary can perform some incoming/outgoing queries (that should be common to the other command with the same needs, but that is another story). We now use the new APIs to do so. The current code behavior is a bit fishy, relying to the fact "default" will be picked as the destination in last resort. I did not altered that, but left various comment to highlight the issue. Differential Revision: https://phab.mercurial-scm.org/D10420

share: use `get_clone_path` Since `hg share` is mostly like clone, do the same changes there. Differential Revision: https://phab.mercurial-scm.org/D10419

init: use `get_clone_path` when suitable `hg init` has this weird feature were you can refer to `[paths]` entry select the path to initialize. We move that code to the new APIs. Differential Revision: https://phab.mercurial-scm.org/D10418

clone: use `get_clone_path` "Surprisingly", the new API is well suited for `hg clone` too. Differential Revision: https://phab.mercurial-scm.org/D10417

incoming: kill the `repo._subtoppath =` hack We do the same as for `hg outgoing`, instead of relying on implicit passing value by monkey punching them onto the repo object, we pass equivalent information by argument to the proper function. This is way cleaner. Differential Revision: https://phab.mercurial-scm.org/D10416

identify: use `get_unique_pull_path` The command only support a single destination. We use the associated API. Differential Revision: https://phab.mercurial-scm.org/D10415

bundle: support multiple destinations `hg outgoing` and `hg push` now support multiple destination. We do the same for `hg bundle`. Various other commands needs this kind of behavior and it would be create to factor this code out for their usage. However this is an adventure for another time. They are some minor change to the tests (in addition to the new test for the feature): * one because I updated a message to plurals, * another one because the error changed, and I actually find it clearer.
