[Automake-NG] [PATCH 02/15] [ng] vars: get rid of VAR_SORTED type

[Stefano Lattarini]

It's basically unused, and the tiny cosmetic enhancements it offers
are not worth the complication of having yet another variable type.

* automake.in (handle_subdirs): Force RECURSIVE_TARGETS to be of
type "VAR_PRETTY" rather than "VAR_SORTED".  This removes the only
actual use of the VAR_SORTED constant.
* lib/Automake/VarDef.pm (VAR_SORTED): Delete.
(@EXPORT, Pod documentation): Adjust accordingly.
* lib/Automake/Variable.pm (output): Don't handle variables of type
VAR_SORTED anymore.
(define): The value of the '$pretty' parameter cannot be VAR_SORTED
anymore.  Adjust internal checks and Pod documentation accordingly.
