Change subject: check_rtp_origin(): Avoid using memcmp for comparing integer
types
......................................................................
check_rtp_origin(): Avoid using memcmp for comparing integer types
in_addr consists only of s_addr, which is an integer type that
can be compared directly. By avoiding memcmp() here we would have
been able to catch Coverity CID#188874 even without Coverity, and
make the code more compact...
