Merge branch 'jt/grep-wo-submodule-odb-as-alternate'

Browse Source 
The code to make "git grep" recurse into submodules has been
updated to migrate away from the "add submodule's object store as
an alternate object store" mechanism (which is suboptimal).

* jt/grep-wo-submodule-odb-as-alternate:
  t7814: show lack of alternate ODB-adding
  submodule-config: pass repo upon blob config read
  grep: add repository to OID grep sources
  grep: allocate subrepos on heap
  grep: read submodule entry with explicit repo
  grep: typesafe versions of grep_source_init
  grep: use submodule-ODB-as-alternate lazy-addition
  submodule: lazily add submodule ODBs as alternates
