termios: Synchronize with latest FreeBSD headers

Adding modified FreeBSD headers to synchronize RTEMS termios with
FreeBSD. Modify termios to support dedicated input and output baud for
termios structure. Updated BSPs to use dedicated input and output baud
in termios structure. Updated tools to use dedicated input and output
baud in termios structure. Updated termios testsuites to use dedicated
input and output baud in termios structure.

Close #2897.
