move log_init & vars to gmid.c, retain logger_main in log.c
this is to let the regression suite compile
add compat/*.o
got doesn't seem to match (say) compat/freezero.o with *.o
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.
