- Remove the old insque() and remque() functions and their manual
page from the compatibility library.
- Add new implementations of insque() and remque() which conform to
IEEE Std 1003.1-2001 to libc. Add a new manual page for them and
connect them to the build.
- Add the prototypes of insque() and remque() to the search.h
header.
