Decompose <sys/termios.h>. The <sys/termios.h> header file is hardlinked to <termios.h>. It contains both the structures and the flag definitions, but also the C library interface that's implemented by the C library. This header file has the typical problem of including too many random things and being badly ordered. Instead of trying to fix this, decompose it into two header files: - <sys/_termios.h>, which contains struct termios and the flags. - <termios.h>, which includes <sys/_termios.h> and contains the C library interface. This means userspace has to include <termios.h> for struct termios, while kernelspace code has to include <sys/tty.h>. Also add a <sys/termios.h>, which prints a warning message before including <termios.h>. I am aware that there are some applications that use this header file as well.

include: further adoption of SPDX licensing ID tags. Mainly focus on files that use BSD 3-Clause license. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. Special thanks to Wind River for providing access to "The Duke of Highlander" tool: an older (2014) run over FreeBSD tree was useful as a starting point.

void cfmakeraw(struct termios *);
Add a new libc function: cfmakesane(3). I've noticed various terminal emulators that need to obtain a sane default termios structure use very complex `hacks'. Even though POSIX doesn't provide any functionality for this, extend our termios API with cfmakesane(3), which is similar to the commonly supported cfmakeraw(3), except that it fills the termios structure with sane defaults. Change all code in our base system to use this function, instead of depending on <sys/ttydefaults.h> to provide TTYDEF_*.
