[PATCH 14/21] repo-settings: split out declarations into a standalone header

[Patrick Steinhardt <ps@pks.im>]

While we have "repo-settings.c", we do not have a corresponding
"repo-settings.h" file. Instead, this functionality is part of the
"repository.h" header, making it hard to discover.

Split the declarations out of "repository.h" and create a standalone
header file with them.
