Alexander Barkov 69911c2710 A joint patch for MCOL-4614, MCOL-4615, MCOL-4660 (decimal to string conversion) 
This patch fixes:
- MCOL-4614 calShowPartitions() precision loss for huge narrow decimal
- MCOL-4615 GROUP_CONCAT() precision loss for huge narrow decimal
- MCOL-4660 Narow decimal to string conversion is inconsistent about zero integral

Changes:
- Implementing Row::getDecimalField()

- Removing double arithmetic from the code printing DECIMAL values
  in TypeHandlerXDecimal::format64() and GroupConcator::outputRow().
  Using Decimal::toString() instead.

- Rewriting Decimal::toStringTSInt64(). The old implementation
  was wrong, too complex and slow (used unnecessary memmove, memcpy).

An additional cleanup:
- Removing the ENGINE=COLUMNSTORE clause from tests for MCOL-4532 and MCOL-4640
  type_decimal.test is combinations-aware. It's run two times with
  default_storage_engine=MyISAM and default_storage_engine=COLUMNSTORE.
  So the CREATE TABLE statements should not specify the engine explicitly.
- Adding --disable_warnings in the old fixed test.
  We needed to suppress warnings when the MyISAM combination is being run.
  Previously the table was erroneously created with ENGINE=COLUMNSTORE
  even with the MyISAM combination run. So warning were not generated.
