interest lifetime is encoded as seconds in ccnl_interest_new

[mfrey]

Hi,

the interest lifetime in NDN interests is set by default to CCNL_INTEREST_TIMEOUT. The constant is in seconds, but the specification states that the lifetime is milliseconds. In ccnl-relay.c

 327     /* currently, the aging function relies on seconds rather than on milli seconds */
 328     i->lifetime = (*pkt)->s.ndntlv.interestlifetime / 1000;    

The lifetime is encoded as seconds, but it should be milliseconds. I propose to set the constant CCNL_INTEREST_TIMEOUT to milliseconds and transform either the field upon reception into seconds or in the aging function (so the field is always milliseconds and nobody gets confused).

Best,
Michael
