[RFC wayland 0/2] Wayland protocol dumper

The idea of wayland protocol dumper came from [1]. And this patch
series implements a prototype of it. I found wayland utilities quite
convenient so I decided to base my work on top of wayland (although
not using libwayland-client or libwayland-server), so it temporarily
(and I hope eventually it can) resides in the wayland source tree.

The program is quite simple now, it uses a socketpair to communicate
with a client and redirect that to the server, dumping the data on the
wire in the process. It only dumps raw data at present.

To use it, you can try:
shell> wayland-tracer [program you want to trace and arguments]

It can be really easy to cut down the data to single messages, though,
producing readable outputs about messages (names and argument values)
is quite far ahead. My plan is to take .xml protocol files as input
and learn things on the fly. I think it possible although I'm not very
sure about details.

Comments and suggestions are welcomed. Feel free to say something about
whether it useful, where it is wrong, how it can improve, etc.
