Philipp Serr 7b11660f4f Prevent concurrent processing of same blob
... by first adding a preliminary index entry and making this fail if
an index entry for the same blob already exists.

A preliminary index entry is characterized by not yet being associated
with a pack. Until now, these entries where added to the index just
like final index entries using index.Store, which silently overwrites
existing index entries.

This commit adds a new method index.StoreInProgress which refuses to
overwrite existing index entries and allows for creating preliminary
index entries only. The existing method index.Store has not been
changed and continues to silently overwrite existing index entries.
This distinction is important, as otherwise, it would be impossible to
update a preliminary index entry after the blob has been written to a
pack.
