fix missing listen on warning printed the wrong value for the hostname

plug a leak all other rules are freeing the value of `listen_addr'

fix automatic guessing of `listen on' default_host needs to be NULL for getaddrinfo(3) to listen on everything.

implement fastcgi strip number

add `log syslog facility' to use a different syslog(3) facility Was requested ages ago by Karl Jeacle, now that there is some better support for configuring the logging there's no excuse to add this. It helps with filtering from syslog.d / syslog.conf.

sort logopt

add log syslog off; don't turn syslog off when log access is specified

typo

allow to change the logging style; introduce some new ones add `log style <style>'; The old default is called `legacy' now, a new default format is added called `condensed', and `common' and `combined' to mimick Apache httpd and nginx (respectively) are also added.

add ability to log to files with log access <path>

fix a reduce/reduce conflict location -> error and locopt -> fastcgi -> error both end up with a optnl that can be reduced to the empty string.

add `fastcgi off' to forceful skip fastcgi for a route

revamp fastcgi configuration: make it per-location this revamps the syntax in the configuration to better match httpd(8) (and in general be less weird) and to allow per-location fastcgi configurations. the bare `param' is now deprecated, but for compatibility it acts like `fastcgi param' would do now. Same story for `fastcgi <pathÂ>'.

plug memleak

make `listen on' defaults on port 1965
