Subject: config: add git_config_get_expiry() from gc.c
X-Git-Tag: v2.13.0-rc0~111^2~6
X-Git-Url: https://git.lorimer.id.au/gitweb.git/diff_plain/77d67977cac46aa6c07c66ce9e2470f00feb9d20

config: add git_config_get_expiry() from gc.c

This function will be used in a following commit to get the expiration
time of the shared index files from the config, and it is generic
enough to be put in "config.c".
