[SPARK-13721][SQL] Support outer generators in DataFrame API
## What changes were proposed in this pull request?
Added outer_explode, outer_posexplode, outer_inline functions and expressions.
Some bug fixing in GenerateExec.scala for CollectionGenerator. Previously it was not correctly handling the case of outer with empty collections, only with nulls.
## How was this patch tested?
New tests added to GeneratorFunctionSuite
