[PATCH v4 00/15] config: make git_config_set die on failure

This is the fourth version of my patch series. Version three of
these patches can be found at [1]. These patches convert the
`git_config_set` family of functions such that they die by
default whenever an error is encountered in persisting configs.
This catches a lot of cases where we wrote configs without
checking the returned status code, thus leading to inconsistent
state witouth even notifying the user.

This version combines both version 2 ([2]) and version 3 of this
patch series in that we first introduce `git_config_set_or_die`
wrappers and converting most call sites to use these. After the
conversion is done, we rename `git_config_set` to
`git_config_set_gently` and adjusting remaining call sites. The
last step was to rename `git_config_set_or_die` to
`git_config_set` in order to get the desired default behavior.

This back-and-forth should hopefully help easing the transition
and review by breaking down the actual transition into small
pieces.
