[PATCH/RFC/GSoC 08/17] rebase-common: let refresh_and_write_cache() take a flags argument

[Paul Tan <pyokagan@gmail.com>]

refresh_and_write_cache() is a handy function for refreshing the index
and writing the resulting index back to the filesystem. However, it
always calls refresh_cache() with REFRESH_QUIET. Allow callers to modify
the behavior of refresh_cache() by allowing callers to pass a flags
argument to refresh_cache().
