tty: Define ASYNC_ replacement bits
Prepare for relocating kernel private state bits out of tty_port::flags
field; tty_port::flags field is not atomic and can become corrupted
by concurrent updates. It also suffers from the complication of sharing
in a userspace-visible field which must be masked.
Define new tty_port::iflags field and new, substitute bit definitions
for the former ASYNC_* flags.
