  o Minor bugfix (configuration):
    - Check for multiplication overflow when parsing memory units inside
      configuration. Fixes bug 30920; bugfix on 0.0.9rc1~46.
Check memunit parsing for overflow in confparse Before, when parsing memunits, if overflow occured it failed silently. Use nowrap u64 math to detect overflow, compare to INT64_MAX and if greater tell user and fail accordingly. 15000000.5 TB fails double check as it a greater floating number than (double)INT64_MAX 8388608.1 TB passes double check because it falls in the same value as (double)INT64_MAX (which is 2^63), but will fail the int check because (uint64_t)d, which is 2^63, is strictly greater than 2^63-1 (INT64_MAX).
