Released 1.3.1 with the following changes from 1.2.15 :
- now, haproxy warns about missing timeout during startup to try to
eliminate all those buggy configurations.

suggested by Cameron Simpson.

test server's health

an "HTTP/1.0 200 OK" response. This is useful to validate multiple proxies
at once.

the session was freed. This has been encountered on Solaris only.

be nice to them by performing a soft stop if pause fails.
Summary of changes :
- 'maxconn' server parameter to do per-server session limitation
- queueing to support non-blocking session limitation
- fixed removal of cookies for cookie-less servers such as backup servers
- two separate wait queues for expirable and non-expirable tasks provide
better performance with lots of sessions.
- some code cleanups and performance improvements
- made state dumps a bit more verbose
- fixed missing checks for NULL srv in dispatch mode
- load balancing on backup servers was not possible in source hash mode.
- two session flags shared the same bit, but fortunately they were not
compatible.
be displayed even in quiet mode.
* display an alert when a listener has no address, invalid or no port, or when
there are no enabled listeners upon startup.
* second batch of socklen_t changes.
* clean-ups from Cameron Simpson.
* because tv_remain() does not know about eternity, using no timeout can
make select() spin around a null time-out. Bug reported by Cameron Simpson.
* client read timeout was not properly set to eternity initialized after an
accept() if it was not set in the config. It remained undetected so long
because eternity is 0 and newly allocated pages are zeroed by the system.
* do not call get_original_dst() when not in transparent mode.
* implemented a workaround for a bug in certain epoll() implementations on
linux-2.4 kernels (epoll-lt <= 0.21).
* implemented TCP keepalive with new options : tcpka, clitcpka, srvtcpka.
