from HEAD to RELENG_5:
Add a "comconsole_speed" loader variable that can be used to change the serial console speed (i386 and amd64 only). If the previous stage boot loader requested a serial console (RB_SERIAL or RB_MULTIPLE) then the default speed is determined from the current serial port speed. Otherwise it is set to 9600 or the value of BOOT_COMCONSOLE_SPEED at compile time.
