[PATCH 001/194] repository: introduce object store field




The object store field will contain any objects needed for access to
objects in a given repository.

This patch introduces the object store but for now it is empty.  C99
forbids empty structs, but common C compilers cope well with them and
this struct will gain members very soon (starting with the next
patch).
