Implement cooperative caching When indexing a file with ref deltas, a temporary cache for the offsets has to be built, as we don't have an index file yet. If the user takes the responsiblity for filling the cache, the packing code will look there first when it finds a ref delta. Signed-off-by: Carlos Martín Nieto <carlos@cmartin.tk>
