setup: start tracking ref storage format
In order to discern which ref storage format a repository is supposed to
use we need to start setting up and/or discovering the format. This
needs to happen in two separate code paths.
- The first path is when we create a repository via `init_db()`. When
we are re-initializing a preexisting repository we need to retain
the previously used ref storage format -- if the user asked for a
different format then this indicates an error and we error out.
Otherwise we either initialize the repository with the format asked
for by the user or the default format, which currently is the
"files" backend.
- The second path is when discovering repositories, where we need to
read the config of that repository. There is not yet any way to
configure something other than the "files" backend, so we can just
blindly set the ref storage format to this backend.
Wire up this logic so that we have the ref storage format always readily
available when needed. As there is only a single backend and because it
is not configurable we cannot yet verify that this tracking works as
expected via tests, but tests will be added in subsequent commits. To
countermand this ommission now though, raise a BUG() in case the ref
storage format is not set up properly in `ref_store_init()`.

Git is a fast, scalable, distributed revision control system with an unusually rich command set that provides both high-level operations and full access to internals.
Git is an Open Source project covered by the GNU General Public License version 2 (some parts of it are under different licenses, compatible with the GPLv2). It was originally written by Linus Torvalds with help of a group of hackers around the net.
Please read the file INSTALL for installation instructions.
Many Git online resources are accessible from https://git-scm.com/ including full documentation and Git related tools.
See Documentation/gittutorial.txt to get started, then see Documentation/giteveryday.txt for a useful minimum set of commands, and Documentation/git-<commandname>.txt for documentation of each command. If git has been correctly installed, then the tutorial can also be read with man gittutorial or git help tutorial, and the documentation of each command with man git-<commandname> or git help <commandname>.
CVS users may also want to read Documentation/gitcvs-migration.txt (man gitcvs-migration or git help cvs-migration if git is installed).
The user discussion and development of Git take place on the Git mailing list -- everyone is welcome to post bug reports, feature requests, comments and patches to git@vger.kernel.org (read Documentation/SubmittingPatches for instructions on patch submission and Documentation/CodingGuidelines).
Those wishing to help with error message, usage and informational message string translations (localization l10) should see po/README.md (a po file is a Portable Object file that holds the translations).
To subscribe to the list, send an email with just “subscribe git” in the body to majordomo@vger.kernel.org (not the Git list). The mailing list archives are available at https://lore.kernel.org/git/, https://marc.info/?l=git and other archival sites.
Issues which are security relevant should be disclosed privately to the Git Security mailing list git-security@googlegroups.com.
The maintainer frequently sends the “What's cooking” reports that list the current status of various development topics to the mailing list. The discussion following them give a good reference for project status, development direction and remaining tasks.
The name “git” was given by Linus Torvalds when he wrote the very first version. He described the tool as “the stupid content tracker” and the name as (depending on your mood):
