[PATCH] repo_config_values: freeze the structure for now

[Junio C Hamano <gitster@pobox.com>]

The configuration and settings per repository is currently in an
unfortunate mess.  Especially given that repo_config_values() cannot
work on any repository instance other than the_repository, moving
more members into this structure is unwelcome.
