faster client pre-1.0: neon prefetching, multithreading

From: solo turn <soloturn99_at_yahoo.com>

i tried to profile also the https client, the results are:

full update, https, server/client on same machine, duration 728sec
(reminder: ra_local took 280sec):

                svn_cl__update

275 39 ne_begin_request, send_request, read_status_line,
                ne_sock_readline, read_ossl, readable_ossl, select,
                select, _poll

(times are not always according to percentage, cause functions may be
called from different callees)

total times:
272 _poll
259 _rename
119 __open
 23 mkdir
 20 unlink
  9 _write

the following points could be time-consuming:
- there is a lot of disk access and network wait time
  which seems not parallel, ie. multithreaded.
- especially urls and their properties seem to be fetched
  in order, without any function which gets an url,
  with the small properties, and the entries, and the
  small properties of the entries in one fetch.
