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