Omar Polo 9d092b607a fix IRI-parsing bug 
Some particularly crafted IRIs can cause a denial of service (DOS).
IRIs which have a trailing `..' segment and resolve to a valid IRI
(i.e. a .. that's not escaping the root directory) will make the
server process loop forever.

This is """just""" an DOS vulnerability, it doesn't expose anything
sensitive or give an attacker anything else.

Omar Polo c836cdfadb handle CGI scripts that replies with the maximum header length allowed 
the 1024 bytes limits is for the META only, not for the whole
response.  That means that the maximum size for the header line is
1029!

Omar Polo 052c9d2403 kill only $pid during regress testing 
before we did `pkill gmid', but that would influence also other
instances of gmid!

Omar Polo bc99d868bc refactoring: imsg everywhere 
use imsg to handle ALL kinds of IPC in gmid.  This simplifies and shorten the
code, and  makes everything more uniform too.

Omar Polo 49b73ba1ab fix "first location" bug 
reported by devel at datenbrei dot de.  The first location would
overwrite the default value for a server, triggering the "`foo' rule
specified more than once" error.  This also needed a small tweak on
how we match locations to avoid breaking other tests.

Omar Polo 35744950aa simplify handle_cgi 
Now that I got rid of the enum+switch, adding more state is easier.
Before, we used an hack to remember if we had read the CGI reply or
not (c->code = -1).

This introduces a new state, handle_cgi_reply that reads the CGI
script reply, logs it, and only then switches to handle_cgi.
handle_cgi itself is cleaner, now it only reads into c->sbuf and send
what it had red.

We even get, almost for free, the 42 error.  If read exists with -1 or
0 from in handle_cgi_reply, we return a proper error to the client.
We can extend this further in the future and also try to validate the
CGI reply (for now we're only looking for a \n).
