[sr-dev] INV_FR_TIME_OUT_FIRST

[Jan Janak]

I am testing serial forking timers with the merged tm module and
noticed that we have INV_FR_TIME_OUT_FIRST defined, in addition to
IN_FR_TIME_OUT_NEXT.

INV_FR_TIME_OUT_FIRST does not seem to be used anywhere neither in
sip-router nor in kamailio. Is this a relict and we can potentionally
remove it and keep INV_FR_TIME_OUT_NEXT only, or do I miss something?
