Resync our strstr.c with the musl version. Removes some debug code and
optimizes one statement in two-way string compare.

Add a missing header when compiling with -DDEBUG

New strstr() implementation from musl libc by Rich Felker. This
version uses the two-way string matching algorithm and is faster
than the old implementation. With this change, ports that check
for strstr having linear complexity time strstr will no longer
replace the libc strstr with a private version.
OK deraadt@ espie@

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
