[PATCH v2 04/13] alloc: add repository argument to alloc_blob_node

[Stefan Beller]

This is a small mechanical change; it doesn't change the
implementation to handle repositories other than the_repository yet.
Use a macro to catch callers passing a repository other than
the_repository at compile time.
