What changes were proposed in this pull request?

Add analyzer support for named function arguments.

Why are the changes needed?

Part of the project needed for general named function argument support.

Does this PR introduce any user-facing change?

We added support for named arguments for the CountMinSketchAgg and Mask SQL functions.

How was this patch tested?

A new suite was added for this test called NamedArgumentFunctionSuite.

I don't think this error is triggered when the config is false right? It is only because the function itself doesn't implement the named argument trait.

Good question, I imagine we probably would not get around to prioritizing overloads soon with this framework. But if we did, would it become necessary to update all the places where these function signatures are defined, from an Option[FunctionSignature] to an Option[Seq[FunctionSignature]]? In contrast, if we go with the latter syntax of a Seq of just one function signature, we wouldn't have to update all those sites later.

However, I imagine such an update would be a fairly mechanical change, and in the interim, we get better compiler enforcement. It seems like this suggestion is better for now to switch the API to return just an Option[FunctionSignature] for now.

Can we add more named argument tests in this file (table-valued-functions.sql) when the function invocation throws exceptions? For example use named arguments for these tests:

select * from explode(explode(array(1)))
-- !query schema
struct<>
-- !query output
org.apache.spark.sql.AnalysisException
{
"errorClass" : "UNSUPPORTED_GENERATOR.NESTED_IN_EXPRESSIONS",

I'd like to make sure the exceptions stay the same.

This is looking good, the only remaining changes left look like following Wenchen's suggestion to change the API to return an Option[FunctionSignature] instead of an Option[Seq[FunctionSignature]] for now (since we don't plan to support overloads in the short term), and some code commenting improvements.

I felt it was because the name I created had the exact same name as the variable above and I didn't want to cause confusion. Also, in other example functions, builder is the variable name used for this kind of object, so I thought it be good to clear up the ambigiuity.

I asked Serge, and the original name is right. There's probably some confusion over the technical difference between argument and parameter. Typically, parameter is what each name is referring to.
