Add fast options to git_repository_open_ext

This adds two streamlined code paths to git_repository_open_ext for
situations where you have specific knowledge of the repo to open
and want a faster open call.

- GIT_REPOSITORY_OPEN_BARE forces the repo to be opened as a bare
  repo avoiding looking for a ".git" subdirectory and parsing the
  config file for core.bare and core.worktree values.  This is
  useful in many server-side configurations.
- GIT_REPOSITORY_OPEN_NO_CONFIG tries to open the open non-bare
  with the assumption that the worktree is the parent of the .git
  directory.  This is only useful in very specific client-side
  circumstances where a short-lived process needs to try to get
  some repo information.
