[SPARK-9069] [SPARK-9264] [SQL] remove unlimited precision support for DecimalType
Romove Decimal.Unlimited (change to support precision up to 38, to match with Hive and other databases). In order to keep backward source compatibility, Decimal.Unlimited is still there, but change to Decimal(38, 18). If no precision and scale is provide, it's Decimal(10, 0) as before. Author: Davies Liu <davies@databricks.com> Closes #7605 from davies/decimal_unlimited and squashes the following commits: aa3f115 [Davies Liu] fix tests and style fb0d20d [Davies Liu] address comments bfaae35 [Davies Liu] fix style df93657 [Davies Liu] address comments and clean up 06727fd [Davies Liu] Merge branch 'master' of github.com:apache/spark into decimal_unlimited 4c28969 [Davies Liu] fix tests 8d783cc [Davies Liu] fix tests 788631c [Davies Liu] fix double with decimal in Union/except 1779bde [Davies Liu] fix scala style c9c7c78 [Davies Liu] remove Decimal.Unlimited
