Implement com(4) interrupt support for receiving data. Add termios terminal support to the com(4) driver with tcsetattr(2) support for configuring the hardware serial settings. Add kernel(7) --console option which can be used to initialize the com(4) driver early for the kernel console with the specified serial settings and window size. Add kernel(7) --text option for overriding the TERM environment variable. Add kernel(7) --disable-logo option for disabling writing the the operating system logo to the console on boot. Add advanced bootloader option to select booting to a serial console on com1. Add bootloader variables and hooks to customize this behavior. Add tix-iso-bootconfig(8) --console, --grub-serial, --serial, and --serial-console options as a convenince to opt into booting to the serial console by default. Add tix-iso-bootconfig(8) --kernel-options option for forwarding additional options to the kernel. The logterminal driver used for tty1 currently assumes that it controls the kernel log, which is not true when com(4) is used as the console, therefore the tty1 driver is currently disabled if a serial console is selected, as a temporary workaround.
