lib/srdb1: store BIGINT result also as 32-bit integer if it fits

BIGINT is always converted to string. Additionally it is now stored as INT too.

MySQL (at least on 64-bit) is returning BIGINT for all "generated" INT values,
like COUNT(*). By storing thee results as INT (if possible), the config script
will be compatible with both 32-bit and 64-bit column values.
