Roll back uintptr_t cast changes after discussions with tedu, otto and
others.

C11 6.5.6.9 says:
When two pointers are subtracted, both shall point to elements of the
same array object, or one past the last element of the array object; the
result is the difference of the subscripts of the two array elements.

In these cases the objects are arrays of char so the result is defined,
and we believe that the report is based on a compiler incorrectly trapping
on defined behaviour.

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

Add strnlen() to libkern.

Avoid using and end pointer since strnlen(string, -1) is legal
and would otherwise result in overflowing the end pointer and
cause strnlen() to return 0. OK sthen@

remove unused variable.

ok millert@ tedu@

add posix_madvise, posix_memalign, strndup, and strnlen. mostly from
brad and millert, with hints from guenther, jmc, and otto I think.
ok previous.
