Patch from Aleksey (Quality Quorum <qqi@world.std.com>):

1. Finally fixes raw interrupts for pc386
    2. Makes some minor cleanup in console and startup
    3. Makes rtems_termios_dequeue_characters() to return count of
       outstanding chars - it allows to simplify console isrs a little
       bit.
    4. pc386 uart modified to be friendlier to termios parameter changes,
       to have minor performance improvement and to take advantage of
       of above termios modification.
