[PATCH v4 0/3] Remove the_repository global for am, annotate, apply, archive builtins

Remove the_repository global variable for the annotate, apply, and archive bulitins.

Changes since V3:

 * Improve commit message in patch 2

Changes since V1:

 * in patch 1, only pass in repo to the bulitin if the repo exists

Changes since V2:

 * drop patch 3, which is a bit more involved to dis-entangle the_repository
 * use a single variable in run_builtin() to keep track of whether or not we
   are operating in a repository

John Cai (3):
  git: pass in repo to builtin based on setup_git_directory_gently
  annotate: remove usage of the_repository global
  archive: remove the_repository global variable

     +
     +    The repo might be NULL, but we should be safe in write_archive() because
     +    it detects if we are outside of a repository and calls
     +    setup_git_directory() which will error.
