Some cleanup suggested during review

This cleans up a number of items suggested during code review
with @vmg, including:

* renaming "outside repo" config API to `git_config_open_default`
* killing the `git_config_open_global` API
* removing the `git_` prefix from the static functions in fileops
* removing some unnecessary functionality from the "cp" command
