test server's health

at once.

Summary of changes :
- 'maxconn' server parameter to do per-server 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.
* fixed a bug where a TCP connection would be logged twice if the 'logasap'
option was enabled without the 'tcplog' option.
* encode_string() would use hdr_encode_map instead of the map argument.
* the logged request is now encoded with '#XX' for unprintable characters
* new keywords 'capture request header' and 'capture response header' enable
logging of arbitrary HTTP headers in requests and responses
* removed "-DSOLARIS" after replacing the last inet_aton() with inet_pton()
* added the '-V' command line option to verbosely report errors even though
the -q or 'quiet' options are specified. This is useful with '-c'.
* added a Red Hat init script and a .spec from Simon Matter <simon.matter@invoca.ch>
* added 'rspdeny' and 'rspideny' to block certain responses to avoid sensible
information leak from servers.
* more examples added into the configuration
