So N is the number of objects and H is hash size? Please don't let me guess.

The reason we keep all hashes together, packed right, is to reduce
cache footprint. Another observation is it takes us usually just 12
bytes or less to uniquely identify an object, which means we could
pack even tighter if we split he object hash into two chunks, do
bsearch in the first chunk with just <n> bytes then verify that the
remaining 20-<b> bytes is matched in the second chunk. This may matter
more when we move to larger hashes. The split would of course be
configurable since different project may have different optimal value,
but default value could be 10/10 bytes.

I just now realized, how do you protect from duplicate chunks? From
this patch, it looks like you could accept two oidlookup chunks just
fine then siliently ignore the first one.

Indentation. I almost thought oid_to_hex() was a separate statement.

Is (int) really necessary? There's no loss in automatically casting
unsigned char to int. But I didn't check C spec, maybe there's some
rules...

This change should belong to the previous patch. This patch alone
can't tell me that entries is a new allocation. If I didn't remember
the last patch, I could not realize that entries should be freed (and
it does not look like it is here)
