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>'.

move struct envlist and alist up

split out iri.h from gmid.h

rename do_accept() -> server_accept()

change log_request to take the code and meta unpacked don't know what i was smoking when I wrote log_request() like that...

parse (and log) the header from fastcgi

simplify request handling get rid of check_path(), it's overly complicated. Instead, inline open_file() in client_read() and rework open_dir() to just use openat() instead of the complicate dance it was doing. Simplify open_dir() too in the process: if the directory entry for the index is not a regular file, pretend it doesn't exist.

call getnameinfo() only once per request

load the certs per listening address

send host addresses to the server process

implement `listen on' Listening by default on all the addresses is so bad I don't know why I haven't changed this before. Anyway. Add a `listen on $hostname port $port' syntax to the config file and deprecate the old "port" and "ipv6" global setting. Still try to honour them when no "listen on" directive is used for backward compatibily, but this will go away in the next next version hopefully. At the moment the `listen on' in server context don't filter the host, i.e. one can still reach a host from a address not specified in the corresponding `liste on', this will be added later.

rename client->addr to raddr (remote address) and keep original length

load_ca: get a buffer instead of a fd We dup(1) the ca fd and send it to various processes, so they fail loading it. Instead, use load_file to get a buffer with the file content and pass that to load_ca which then loads via BIO.
