ignore REST message "overhead" except the actual data.

DRILL-7502: Invalid codegen for typeof() with UNION

Also fixes DRILL-6362: typeof() reports NULL for primitive

columns with a NULL value.

typeof() is meant to return "NULL" if a UNION has a NULL

value, but the column type when known, such as for non-UNION


Also fixes DRILL-7499: sqltypeof() function with an array returns

"ARRAY", not type. This was due to treating REPEATED like LIST.

Handling of the Union vector in code gen is problematic

with about three special cases. Existing code handled two

of the cases. This change handles the third case.

Figuring out the change required poking around quite a bit

of unclear code. Added comments and restructuring to make

that code a bit more clear.

The fix modified code gen for the Union Holder. It can now

"go back in time" to add the union reader at the point we

need it.

DRILL-6832: Removes the old "unmanaged" external sort

When the "managed" external sort was implemented a couple

of years back, we retained the original "unmanaged" version
