Make sure that the trailing NUL is considered part of the string and can
be found.

33d6e0ff68 lib/test_string.c: avoid masking memset16/32/64 failures 
If a memsetXX implementation is completely broken and fails in the first
iteration, when i, j, and k are all zero, the failure is masked as zero
is returned.  Failing in the first iteration is perhaps the most likely
failure, so this makes the tests pretty much useless.  Avoid the
situation by always setting a random unused bit in the result on
failure.

d6b28e0996 lib: add module support to string tests 
Extract the string test code into its own source file, to allow
compiling it either to a loadable module, or built into the kernel.
