[PATCH] tty: Fix bits and note more bits to fix

If your driver implements "break on" and "break off" this ensures you won't
get multiple overlapping requests or requests in parallel.  If your driver
has its own break handling then its still your problem as the driver
author.

Break is also now serialized against writes from user space properly but no
new guarantees are made driver level about writes from the line discipline
itself (eg flow control or echo)
