On a system with 30 extensions listed by xdpyinfo, truss -c
reports this saves quite a few system calls by batching the
QueryExtension requests instead of a round-trip for each one:

                      Xlib      xcb
writev                  40       11
poll                    80       22
recv                   117       29
total (*)              464      296

(*) total includes all system calls, including many not shown since
their count did not change significantly.   There was one additional
set of open/mmap/close etc. for loading the added libX11-xcb library.

Over a tcp connection, this reduced both the number of packets,
and due to tcp packet header overhead, the overall amount of data:

                      Xlib      xcb
TCP packets             93       35
TCP bytes            11554     7726

- Combine common modeline printing code into single function
- Don't return 0 unless extension isn't supported, since that
  makes xdpyinfo report the extension isn't supported.
- Don't exit immediately if some information is not available,
  since other info may be present.

The only other information I could see to query in the Composite 0.4
protocol spec is the Composite Overlay Window XID, but the request to
get that ID has the side effect of mapping the overlay window, and
xdpyinfo shouldn't have side effects like that.
