olpc-update and staccatto connections

Hi Scott,

would it be possible to change olpc-update to use a single connection
rather than connecting for each directory?

Reasons for this

 - They lead to bad performance over high-latency links - like XOs in
NZ, connecting over satellite or over a noisy RF.
 - On the XS, we are running rsync behind xinetd - the staccatto
connections trigger the DoS protections.

The main reason _for_ requesting each subdir separately would be to
minimise memory use on the both server and client side, but with rsync
3 that is no longer the big issue. XO and XS will soon both be on
rsync v3 so I think it's safe to go with it. Should simplify the
client code, and make the process much faster.

cheers,
