kill unused variable
leftover from the handle_imsg_log -> do_log transition.
allow sending fd to log on to the logger process
the logger process now can receive a file descriptor to write logs to. At the moment the logic is simple, if it receives a file it logs there, otherwise it logs to syslog. This will allow to log on custom log files.
wait for logger after fatal()
With -f, when the main process exits after a fatal() (usually) the shell prompt is printed before the logger message. This adds a small poll to wait for the logger process to exit.
lower log priority for fatal errors from CRIT to ERR
found by Anna, thanks!
move all sandbox-related code to sandbox.c
while there, add capsicum for the logger process
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.
fix out-of-bounds access
obviously msg[datalen] is an off-by-one
move log_init & vars to gmid.c, retain logger_main in log.c
this is to let the regression suite compile
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.
