Omar Polo 8ad1c57024 fastcgi: a first implementation 
Not production-ready yet, but it's a start.

This adds a third ``backend'' for gmid: until now there it served
local files or CGI scripts, now FastCGI applications too.

FastCGI is meant to be an improvement over CGI: instead of exec'ing a
script for every request, it allows to open a single connection to an
``application'' and send the requests/receive the responses over that
socket using a simple binary protocol.

At the moment gmid supports three different methods of opening a
fastcgi connection:

 - local unix sockets, with: fastcgi "/path/to/sock"
 - network sockets, with: fastcgi tcp "host" [port]
   port defaults to 9000 and can be either a string or a number
 - subprocess, with: fastcgi spawn "/path/to/program"
   the fastcgi protocol is done over the executed program stdin

of these, the last is only for testing and may be removed in the
future.

P.S.: the fastcgi rule is per-location of course :)

Omar Polo 2c3e53dac6 give each server process its own socket for the executor 
this fixes a bug introduced with the prefork mechanics: every server
process shared the same socket, and this would cause a race condition
when multiple server processes asked for a script cgi being executed.

This gives each server process its own socket to talk to the executor,
so the race cannot happen.

Omar Polo 49b73ba1ab fix "first location" bug 
reported by devel at datenbrei dot de.  The first location would
overwrite the default value for a server, triggering the "`foo' rule
specified more than once" error.  This also needed a small tweak on
how we match locations to avoid breaking other tests.
