[PATCH v2 0/3] More add_submodule_odb() cleanup in merge code

This is on jt/grep-wo-submodule-odb-as-alternate (unlike version 1) because that branch introduces another usage of repo_submodule_init(), and I need to update it.

The main change from version 1 is that I have introduced a patch (patch
2) that teaches repo_submodule_init() to support submodules with
unabsorbed gitdirs, which means that I no longer need the original patch
1 that updated t6437 to absorb all git dirs.

Once again, all these patches work under GIT_TEST_MERGE_ALGORITHM=recursive and GIT_TEST_MERGE_ALGORITHM=ort (and when that envvar is unset, for good measure).

I have also tested it with the "DO NOT SUBMIT" patch 3 from version 1.

Jonathan Tan (3):
  submodule: remove unnecessary unabsorbed fallback
  repository: support unabsorbed in repo_submodule_init
  revision: remove "submodule" from opt struct
