termios. These are non-standard interfaces but have a precedence: There are
similar interfaces in AIX.

Sigh... removed. We don't need any more almost standard interfaces.
Sigh... removed. We don't need any more almost standard interfaces! (SVN
revision 4968 if you want the short-lived code).
* include/termios.h and lib/termios/*: Open the existing, standard termios
interfaces to permit some non-standard baud settings. The new termios definitions
still supports the POSIX standard except that it does not strictly enforce
baud rate settings, permitting some non-portable, but useful baud rate settings
(this is what the short-lived AIX-like interfaces would have accomplished as well).
* include/termios.h and lib/termios/*: Redesigned yet again (this is getting
painful. NuttX now supports the BOTHER baud setting just as Linux does. termios
Bxxx definitions are again encoded; cf[set|get][o|i]speed now deal with only the
encoded values. If the encoed baud is set to BOTHER, then the values in the (non-
standard) c_ispeed and c_ospeed baud values may be accessed directly.
