localrepo: move repo creation logic out of localrepository.__init__ (API)...

localrepo: move repo creation logic out of localrepository.__init__ (API) It has long bothered me that local repository creation is handled as part of localrepository.__init__. Upcoming changes I want to make around how repositories are initialized and instantiated will make the continued existence of repository creation code in localrepository.__init__ even more awkward. localrepository instances are almost never constructed directly: instead, callers are supposed to go through hg.repository() to obtain a handle on a repository. And hg.repository() calls localrepo.instance() to return a new repo instance. This commit teaches localrepo.instance() to handle the create=True logic. Most of the code for repo construction has been moved to a standalone function. This allows extensions to monkeypatch the function to further customize freshly-created repositories. A few calls to localrepo.localrepository.__init__ that were passing create=True were converted to call localrepo.instance(). .. api:: local repo creation moved out of constructor ``localrepo.localrepository.__init__`` no longer accepts a ``create`` argument to create a new repository. New repository creation is now performed as part of ``localrepo.instance()`` and the bulk of the work is performed by ``localrepo.createrepository()``.
