Remove the str(n)dup inlines from string/bits/string2.h. Although inlining

Browse Source 
calls with constant strings shows a small (~10%) performance gain, strdup is
typically used in error reporting code, so not performance critical.
Remove the now unused __need_malloc_and_calloc related defines from stdlib.h.

Rename existing uses of str(n)dup to __str(n)dup so it no longer needs to be
redirected to a builtin.  Also building GLIBC with -Os now no longer shows
localplt or linkname space failures (partial fix for BZ #15105 and BZ #19463).
