QUIC: added proper logging of special values.

Browse Source 
A number of unsigned variables has a special value, usually -1 or some maximum,
which produces huge numeric value in logs and makes them hard to read.

In order to distinguish such values in log, they are casted to the signed type
and printed as literal '-1'.
