Move UCB-licensed code from 4-clause to 3-clause licence. Patches provided by Joel Baker in PR 22280, verified by myself.

/* $NetBSD: cfgetospeed.c,v 1.7 2003/08/07 16:44:12 agc Exp $ */
Initial checkin of termios directory. The code used to be in gen/termios.c, but has been split out so that NetBSD users don't trip over the extensions that intrude into the POSIX namespace.

If port provides __weak_alias(), provide an Standard C and POSIX pure identifier namespace by renaming non standard functions and variables such that they have a leading underscore. The library will use those names internally. Weak aliases are used to provide the original names to the API. This is only the first part of this change. It is most of the functions which are implemented in C for all NetBSD ports. Subsequent changes are to add the same support to the remaining C files, to assembly files, and to the automagically generated assembly source used for system calls. When all of the above is done, ports with weak alias support should add a definition for __weak_alias to <sys/cdefs.h>.
