Add framework for resolving (pun intended) libc namespace issues, using
wrapper .h files and asm labels to let internal calls resolve directly and
not be overridable or use the PLT. Then, apply that framework to most of
the functions in stdio.h, string.h, err.h, and wchar.h. Delete the
should-have-been-hidden-all-along _v?(err|warn)[cx]? symbols while here.

tests clean on i386, amd64, sparc64, powerpc, and mips64

Sprinkle END() in some straightforward *.S files that have ENTRY(). The
resulting *.o have "FUNC" symbols with size set.

Import new amd64 assembly versions of strchr/index, strrchr/rindex,
and strlen that provide a significantly faster performance than our
previous .c or .S implementations. Based on NetBSD's code.
