Hi,

this is (again) a series of cleanup in tty. I am trying to rework
tty+serial to avoid limitations of devices (so called NR_UART or
tty_alloc_driver()'s first parameter). And the below popped up while
crawling through the code. So this is only a prep cleanup.

* many tty flags are now enums
* many functions were improved for readability
* quite a few unused or old code dropped

In particular, the runtime behaviour of the kernel before and after the
changes is supposed to be bug to bug compatible (except moxa's ioctl
and ISA evils dropped). That is, noone should notice.

[v2]
  * use serial_port_in/out() helpers in 26/30 (and not use serial_in/out())
  * the last patch is new
