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 b9c9123b8e fix signal handling so it works on linux too 
it seems that linux calls the signal handlers even when we're waiting
on sigwait for that signal.  Work around that.

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 2c3e53dac6 give each server process its own socket for the executor 
this fixes a bug introduced with the prefork mechanics: every server
process shared the same socket, and this would cause a race condition
when multiple server processes asked for a script cgi being executed.

This gives each server process its own socket to talk to the executor,
so the race cannot happen.

move vhost_should_log call to server.c 
log.o is linked to some regress/ stuff.  Calling from there a vhost_*
function means that we should link the regress/stuff to server.o too
(and that would pull in other stuff...).  Moving the call is easier,
and also probably better.

Include gmid.h as first header in every file, as it then includes
config.h (that defines _GNU_SOURCE for instance).

Fix also a warning about unsigned vs signed const char pointers in
openssl.

Omar Polo 3cb3dd4d42 accept4 -> accept 
accept4(2) isn't part of any standard (even though it'll be part in
the future) and raises warnings on some linux distro.  Moreover, we
don't have thread that may fork at any time, so doing a mark_nonblock
after isn't a big deal.

Omar Polo 9356f61a63 BUFSIZ is variable, we need *exactly* 1024 
Using BUFSIZ in sbuf is not OK.  It's variable, and in various places
we assume that sbuf is 1024 (like handle_cgi_reply).  We could patch
those, but we aren't sure BUFSIZ is >= 1024!  Let's keep the hardcoded
number.

(found by debugging on arch on amd64, where BUFSIZ is bigger)

Omar Polo 27b2fa9ae5 don't mmap 
Before we mmap(2) file for reading, and use a buffer to handle CGI
scripts.  Turns out, for sequential access over the whole mmap isn't
better than our loop on read.  This has also the additional advantage
that we can use handle_cgi (now handle_copy) for both files and CGI,
which is pretty cool.

This also fixes a nasty bug where we could hang a connection forever,
because we scheduled the wrong type of event (read on POLLOUT and
write on POLLIN, it's the other way around!)

Omar Polo a6e689d745 fix config reload 
the old server processes would stick around waiting on the signals
events.  While there, also drop the `struct server_events' and define
events as globals.
