Merge branch 'jc/pass-repo-to-builtins'

The convention to calling into built-in command implementation has
been updated to pass the repository, if known, together with the
prefix value.

* jc/pass-repo-to-builtins:
  add: pass in repo variable instead of global the_repository
  builtin: remove USE_THE_REPOSITORY for those without the_repository
  builtin: remove USE_THE_REPOSITORY_VARIABLE from builtin.h
  builtin: add a repository parameter for builtin functions
