strcpy() performs no bounds checking on the destination buffer. This
could result in linear overflows beyond the end of the buffer, leading
to all kinds of misbehaviors. The safe replacement is strscpy().

Moreover, when the size of the destination buffer cannot be obtained
using "sizeof", use the memcpy function instead of strscpy.
