[Automake-NG] [PATCH 00/15] Simplify and refacotor variable handling a bit

[Stefano Lattarini]

Far from the sweeping simplifications I was hoping for when I started
writing this series, but they are good to go IMHO.  A better cleanup
(which I still hope I'll be able to do eventually) will probably require
a rewrite of the Automake::Variable and Automake::VarDef modules :-/

OK for ng/master?  I will push in a couple of days if there is no
objection.

Regards,
  Stefano

  [ng] cleanup: remove unused private variables in Automake::Variable
  [ng] vars: get rid of VAR_SORTED type
  [ng] vars: get rid of VAR_SILENT type
  [ng] tests: spy behaviour of '+=' with GNU make
  [ng] tests: Automake should let us append to undefined variables (someday)
  [ng] refactor: support comments only for VarDef, not for ItemDef too
  [ng] VarDef: store comments and values as a perl array
  [ng] vars: simplify logic for appending conditionally
  [ng] vars: keep track of conditionals in appended values and comments
  [ng] vars: get rid of VAR_ASIS / VAR_PRETTY distinction
  [ng] refactor: change signature of 'define_variable()'
  [ng] cleanup: prefer 'define_variable' over 'define_pretty_variable'
  [ng] rename: define_pretty_variable -> define_cond_variable()
  [ng] cosmetics: avoid redundant use of '&' in subroutine calls
  [ng] vars: remove some safety checks in Automake::Variable::define
