one FastCGI connection per client
FastCGI is designed to multiplex requests over a single connection, so
ideally the server can open only one connection per worker to the
FastCGI application and that's that.
Doing this kind of multiplexing makes the code harder to follow and
easier to break/leak etc on the gmid side however. OpenBSD' httpd
seems to open one connection per client, so why can't we too?
One connection per request is still way better (lighter) than using
CGI, and we can avoid all the pitfalls of the multiplexing (keeping
track of "live ids", properly shut down etc...)

copy only `len' bytes, not the whole buffer
We ended up copying too much data from the fastcgi process.

new I/O handling on top of bufferevents
This is a big change in how gmid handles I/O. Initially we used a
hand-written loop over poll(2), that then was evolved into something
powered by libevent basic API. This meant that there were a lot of
small "asynchronous" function that did one step, eventually scheduling
the re-execution, that called each others in a chain.
The new implementation revolves completely around libevent'
bufferevents. It's more clear, as everything is implemented around the
client_read and client_write functions.
There is still space for improvements, like adding timeouts for one, but
it's solid enough to be committed as is and then further improved.

log more details for FastCGI errors
add the reported request id if there's a mismatch and both the gai error
and the errno value if getnameinfo fails.

fastcgi completely asynchronous
This changes the fastcgi implementation from a blocking I/O to an
async implementation on top of libevent' bufferevents.
Should improve the responsiveness of gmid especially when using remote
fastcgi applications.

gracefully shut down fastcgi backends
we need to delete the events associated with the backends, otherwise
the server process won't ever quit.
Here, we add a pending counter to every backend and shut down
immediately if they aren't handling any client; otherwise we try to
close them as soon as possible (i.e. when they close the connection to
the last connected client.)
