HV: rewrite strncpy_s to be iso c11 compliant

Browse Source 
Per C11 standard (ISO/IEC 9899:2011): K.3.7.1.4

1. Copying shall not take place between objects that overlap;
2. If there is a runtime-constraint violation, the strncpy_s function sets
   s1[0] to '\0\;
3. The strncpy_s function returns zero if there was no runtime-constraint
   violation. Otherwise, a nonzero value is returned.
4. The function is implemented with memcpy_s() because the runtime-constraint
   detection is almost same.
