New description:

 Statistics counters are unsigned int (32bit) and integer values in CC are
 signed int (32bit).
 If a counter value becomes 2147483648 (2^31), -2147483648 is sent to stats
 daemon.

 One of solutions is to change "integer" type to signed 64bit in
 src/lib/cc/data.h and add unsigned 64bit support to JSON output. Also
 change counter type to unsigned 64bit int.

 python may treat 64bit unsigned integer numbers.
