Conversation
Add commonly required POSIX/BSD interfaces that portable command-line utilities expect but that were missing from the C library: - include/paths.h: _PATH_DEFPATH and the other standard default paths. - include/sys/ttydefaults.h: BSD default control-character and terminal flag definitions. - include/termios.h: define the IUTF8 input flag.

Summary
Add commonly required POSIX/BSD interfaces that portable command-line utilities expect but that were missing from the C library:
include/paths.h:_PATH_DEFPATHand the other standard default paths.include/sys/ttydefaults.h: BSD default control-character and terminal flag definitions.include/termios.h: define theIUTF8input flag.Impact
New header files only, no existing code is modified. Required by portable command-line utilities (e.g. toybox) that include these headers unconditionally.
Testing
Built and booted
sim:nshsuccessfully with the new headers in place.
