Here's the series I mentioned earlier in the thread to cache loose
objects when answering has_object_file(..., OBJECT_INFO_QUICK). For
those just joining us, this makes operations that look up a lot of
missing objects (like "index-pack" looking for collisions) faster. This
is mostly targeted at systems where stat() is slow, like over NFS, but
it seems to give a 2% speedup indexing a full git.git packfile into an
empty repository (i.e., what you'd see on a clone).

I'm adding René Scharfe and Takuto Ikuta to the cc for their previous
work in loose-object caching.

The interesting bit is patch 8. The rest of it is cleanup to let us
treat alternates and the main object directory similarly.

This cleanup is actually really valuable, and affects much more than 
this application.

I really think it is a good idea, and hope it doesn't cause too much 
trouble as the topic is cooking.
