Kamailio functions and macros missing in sip-router/ut.h

This is the supplemental file to sip-router/ut.h, the contents of this
file was taken from kamailio/ut.h and it contains only functions,
variables and defines which are missing in sip-router/ut.h

Kamailio modules that included ut.h should be modified to include
"lib/kcore/km_ut.h" _in addition to_ "../../ut.h"
