Now the serial console support is partially working.
* grub/asmstub.c (serial_checkkey): Specify a pointer to TIMEOUT
as the fifth argument to select.
(serial_get_port): New function. Just a dummy.
(serial_init): If a serial device is opened, close SERIAL_FD
before opeing a new serial device.
Don't specify O_NDELAY to open.
* stage2/builtins.c [SUPPORT_SERIAL]: Include serial.h.
(serial_func): New function.
(builtin_serial): New variable.
(terminal_func): New function.
(builtin_terminal): New variable.
(builtin_table): Add pointers to BUILTIN_SERIAL and
BUILTIN_TERMINAL.
* stage2/char_io.c [SUPPORT_SERIAL]: Include serial.h.
(getkey) [SUPPORT_SERIAL]: If both TERMINAL_CONSOLE and
TERMINAL_SERIAL are set in TERMINAL simultaneously, print a
warning and force the console terminal.
(checkkey) [SUPPORT_SERIAL]: If TERMINAL_SERIAL is set in
TERMINAL, call serial_checkkey.
(grub_putchar) [SUPPORT_SERIAL]: If TERMINAL_SERIAL is set in
TERMINAL, call serial_putchar. If C is a newline, print a
carriage return, before printing a newline.
