0f67de14e6 Use more optimized version of memmove
On ARM there is currently no assembler optimized memmove in libc.
There is however a more optimized bcopy which copies long instead
of bytes where possible. This almost doubles the performance in
best case.

af00228b70 Revert "libc: memmove(): non-overlapping block optim."
This reverts commit 80fba9a2fe,
which caused the system to not boot anymore, aborting with:
"java.lang.RuntimeException: Missing static main on com.android.server.SystemServer".

e44cb1a35c Fix return value.
Return a valid pointer (not NULL) when the character "c" is at the end of "src".

Example:
  memccpy(dest, "xzy", 'y', 3) should return dest+3 rather than null.
