[PATCH 0/2] fast-import: tag any object by sha1

fast-export can export annotated tags that annotate any type of object. It specifies objects via mark references and fast-import accepts this.

fast-import also allows to specify objects via sha1, and to query sha1
for a object being imported. So it should allow to tag a pre-existing
or being-imported objects by their sha1. And it currently does not:
- for pre-existing it kind of assumes it is a OBJ_COMMIT, read_sha1_file()s
  and checks only for (size >= 46), weird
- for being-imported objects it calls read_sha1_file too and fails

Just make it produce expected tags in these cases. Add a test for this.

  fast-import: add tests for tagging blobs
  fast-import: allow to tag newly created objects
