[00/31] Kill the_repository in sha1-name.c

Message

This whole series is to fix a known issue from
ao/submodule-wo-gitmodules-checked-out. Commit 76e9bdc437 (submodule:
support reading .gitmodules when it's not in the working tree -
2018-10-25) makes "git grep --recurse-submodules" print

    warning: nested submodules ... not supported yet

one line per submodule. And it's really annoying when a repo has lots
of (non-nested) submodules.

Fixing it requires resolving an extended SHA-1 syntax from a separate
repository. Which basically means the whole sha1-name.c has to be
aware of 'struct repository' (and a bit more from refs.c as well).

Technically merge-recursive.c, tree-walk.c and config.c have to take
'struct repository *' too, but I reduce the scope a bit since it's
already long.

The main fix is 28/31. The rest is just converting code to use 'struct
repository *'. Patches after 28/31 are technically not needed, but
since I have converted most of sha1-name.c, might as well convert the
rest.

There is a new function get_oidf() from another series on 'pu', which
can't be converted right now of course. But it could be fixed easily
later. It also causes a conflict in cache.h but resolving is straight
forward.
