move print_conf and make it take the config as argument

use fatal/fatalx instead of err/errx in daemon code

parse_conf: don't die on error, return -1 this avoids having the daemon dieing on SIGHUP with a bad config file.

don't have the config being a global

move hosts into the config struct

move fastcgi from global var to the config struct while here also make them a list rather than a fixed-size array.

readd proxy certs and `require client ca' support Was temporarly disabled during the transition to real privsep. While here, fix a memory leak when using `require client ca'. Also, avoid leaking info about the parent address space layout to server processes by not sending pointer values.

keep cert/key/ocsp path as strings and don't send them via imsg

move some new_* functions from parse.y to utils.c

rework the daemon to do fork+exec It uses the 'common' proc.c from various OpenBSD-daemons. gmid grew organically bit by bit and it was also the first place where I tried to implement privsep. It wasn't done very well, in fact the parent process (that retains root privileges) just fork()s a generation of servers, all sharing *exactly* the same address space. No good! Now, we fork() and re-exec() ourselves, so that each process has a fresh address space. Some features (require client ca for example) are temporarly disabled, will be fixed in subsequent commits. The "ge" program is also temporarly disabled as it needs tweaks to do privsep too.

use fatal() in code used in the daemon

switch to the more usual log.c

rename PROC_MAX to PREFORK_MAX

provide a more usual fatal fatal usually appends the error string. Add 'fatalx' that doesn't. Fix callers and move the prototypes to log.h

send capsicum/landlock/seccomp hack to Valhalla
