Revision: 10173
Log message:
      Added the "var1" jumbo branch.
      
      This is the base port, no changes yet.
      
      var1:
         Convert the source code in 0.9.8 so that it matches the
         source structure in 0.9.9.
      
         There should be no real semantical changes to the OMake
         language.  This is a code change only.
      
         Major architectural changes:
            - The Scope* is folded into the variable, it is
              no longer a separate field.
              
              The right way to think is that there are _not_
              3 environments, there are 3 kinds of variables
              and a single environment.
       
              There are 4 classes of variables (the "any"
              replaces the 0.9.8 default variable).
                  VarPrivate: private, statically scoped
                  VarThis: current object, dynamically scoped
                  VarVirtual: global, dynamically scoped
                  VarAny: the usual default 
      
            - Use venv_find_var_virtual to get a global var.
           
            - Omake_ir_ast now structurally looks like 0.9.9.
      
         There is an exception:
            - export variables are computed at compile time
              in Omake_ir_ast, instead of at runtime.
