move print_conf and make it take the config as argument

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.

fix typo

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

remove foreground / verbose from config set them as global vars; rename foreground -> debug

move logger() prototype to gmid.h and delete logger.h

make server_init and server_configure_done 'public' server_configure_done is the code we ran in IMSG_RECONF_END splitted in a separate functions. This is all needed for ge.c which doesn't do privsep but needs to bootstrap the server process.

move log_request to gmid.c so that ge can provide its own log_request without requiring a separate logger process.

move make_socket to config.c and make it private

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

drop now unused dispatch_imsg
