New users trying out Got for the first time have reported trouble with finding a way to create a new repository, based on their assumption that Got works like Git which provides a 'git init' command. It doesn't cost us much effort to keep this command available in both programs to make discovery a bit easier for new users coming from Git.

Found while running 'got clone' against a git9 server, after an unrelated issue was reported by Lucas on IRC, thanks! ok op@

Despite API callers not requesting it, we collect line metadata due to NULL pointer checks missing a level of indirection. Reported by Kyle Ackerman. ok op and stsp

spotted while investigating for another leak spotted by Kyle Ackerman. ok stsp@ and jamsek

They're no longer used.

at this point we can't know if the client has disconnected, we just finished parsing the fcgi parameters and started handling the reply. We'll know whether the client disconnected only later, while trying to send the page content.

in case of multiple parameters with the same name, use the last matching one.

only fatal*() and log_warn*() are now logged by default. log_info() is hidden behind a -v and log_debug behind -vv. Makes gotd and gotwebd way less chatty. ok stsp@

Instead of allocating a whole set of temp fd per `listen' directive, just use a global set per "sockets" process. This is fine since gotwebd doesn't keep multiple connections open at the same time, once it enters gotwebd_process_request() it won't exit until all the page has been processed. (this because we don't have async APIs for got operations.) ok stsp@

gotd and gotwebd are using almost the same log.c file, so unify. This only slightly changes gotwebd logs to include the process name, like gotd. ok stsp@

ok stsp@

Now that `listen' is a top-level, `unix_socket_name' is useless. The default socket remains /var/www/run/gotweb.sock, to listen on an alternate socket now `listen on socket "/some/other/sock" can be used. part of a larger diff that's ok stsp@

gotwebd only uses the server name (i.e. the Host HTTP header) to match the server blocks. Since gotwebd by design sits behind an http server which is expected to filter virtual hosts, there's little point in having `listen' per-server. part of a larger diff that's ok stsp@

it's no longer required for the host:port tuple to be used only by one server.

- don't assume an implicit "listen on socket" when another listen was specified in a server block - allow servers to share the sockets they're listening on - fix unix_socket_name; now it's actually used - remove `listen on socket off' and `unix_socket off' options that are now no longer useful - unify the internal handling of the sockets, i.e. don't consider unix socket special. ok tracey@

h is free'd by add_addr in case of error, but we still leak the getaddrinfo result. while here make the check strictier: addr_addr() fails with -1.

these functions are expected to return -1 on failure, be strict about it.
