packfile: create packfile.Index and reuse it
There was an internal type (i.e. storage/filesystem.idx) to
use as in-memory index for packfiles. This was not convenient
to reuse in the packfile.
This commit creates a new representation (format/packfile.Index)
that can be converted to and from idxfile.Idxfile.
A packfile.Index now contains the functionality that was scattered
on storage/filesystem.idx and packfile.Decoder's internals.
storage/filesystem now reuses packfile.Index instances and this
also results in higher cache hit ratios when resolving deltas.
