Add a couple of mips-specific string funcs.

Port the generic optimized string funcs from glibc, with some tweaks
  to cut their size a little.  The main change is making memmove
  call memcpy for forward copying to trim redundant code.
Make use of both the generic and arch-specific speed-optimized string
  funcs configurable.  Arch-specific take precedence over generic,
  and generic takes precedence over basic size-optimized uClibc funcs.
