localrepo: support shared repo creation
Previously, hg.share() had its own logic for creating a new
repository on the filesystem.
With the recent introduction of the createopts dict for passing
options to influence repository creation, it is now possible
to consolidate the repo creation code for both the normal and
shared use cases.
This commit teaches the repo creation code in localrepo to
recognize when we're creating a shared repo and to act
appropriately.
Meaningful behavior should be identical. However, there are a
few subtle changes:
* The .hg/requires file is written out in sorted order (rather
than having share-related requirements appended at end).
* The .hg directory is created with notindexed=True when a shared
repo is being created.
