Subject: [PATCH 1/3] builtin: add a repository parameter for builtin functions

From: John Cai <johncai86@gmail.com>

In order to reduce the usage of the global the_repository, add a
parameter to builtin functions that will get passed a repository
variable.

This commit uses UNUSED on most of the builtin functions, as subsequent
commits will modify the actual builtins to pass the repository parameter
down.
