path: move the url parsing and related attribute setting to a method This will make it simpler to reuse this logic in the next changeset.

peer-or-repo: remove the now unused function We do not need it anymore.

peer-or-repo: build a repo directly in the `repo` function We skip the ambiguous _peerorrepo function to explicitly build a repo within the dedicated function. The peer scheme are therefore no longer considered to build the object.

peer-or-repo: build a peer directly in the `peer` function We skip the ambiguous _peerorrepo function to explicitly build a peer within the dedicated function. This mean explicitly getting a peer from an explicitly create repository when necessary.

static-http: have `statichttprepo.instance` return a peer object It previously returned a statichttprepo object which could not be used for anything but creating a peer. So lets put it into the peer bucket with a peer behavior.

scheme: move the drive letter checking in its own function This help the readability of the main function as is was taking much more room than the main logic.

peer-or-repo: split the scheme between repo and peer Some of the scheme will always produce a peer and some will always produce a repository. So lets use different mapping to reduce the ambiguity.

peer-or-repo: stop relying on AttributeError in `islocal` This will confused pytypes in a future changeset.

repo-or-peer: deprecate calling `islocal` on non-path object There object have a `.local()` method and should use it.

share: stop using 'islocal' with repo instance Having this level of polymorphism of the `islocal` function is weird, and we already have a way to know if the repo is local from the object itself. We are about to deprecate passing a non-bytes object to `islocal`, so clean this up beforehand. We might want to clean up this function too in the future, however this is another adventure.
