Avi Kivity 0bde5906b3 Merge "cql3: detect and handle int overflow in aggregate functions #5537" from Benny
"
Fix overflow handling in sum() and avg().

sum:
 - aggregated into __int128
 - detect overflow when computing result and log a warning if found

avg:
 - fix division function to divide the accumulator type _sum (__int128 for integers) by _count

Add unit tests for both cases

Test:
  - manual test against Cassandra 3.11.3 to make sure the results in the scylla unit test agree with it.
  - unit(dev), cql_query_test(debug)

Fixes #5536
