Although the prototype of memset() is already defined in OpenSslSupport.h,
the function was never implemented. It was fine since a macro was
designed to replace all memset() with SetMem() after including
OpenSslSupport.h. However, since openssl 1.0.2j, a new function pointer
in crypto/mem_clr.c requires the "real" memset() or the program would
crash due to the NULL function pointer access. This commit implements
memset() (just a wrapper of SetMem()) to avoid the potential crash.
