Implement 'extern' declaration modifier.
The 'extern' declaration modifier provides a more convenient way of interfacing Dafny code with C# source files and .Net DLLs. We support an 'extern' keyword on a module, class, function method, or method (cannot extern ghost). We check the CompileNames of all modules to make sure there are no duplicate names. Every Dafny-generated C# class is marked partial, so it can potentially be extended. The extern keyword could be accompanied by an optional string naming the corresponding C# method/class to connect to. If not given the name of the method/class is used. An 'extern' keyword implies an {:axiom} attribute for functions and methods, so their ensures clauses are assumed to be true without proof. In addition to the .dfy files, the user may supply C# files (.cs) and dynamic linked libraries (.dll) on command line. These will be passed onto the C# compiler, the .cs files as sources, and the .dll files as references. As part of this change the grammar was refactored some. New productions are - TopDecls - a list of top-level declarations. - TopDecl - a single top-level declaration - DeclModifiers - a list of declaration modifiers which are either 'abstract', 'ghost', 'static', 'protected', or 'extern'. They can be in any order and we diagnose duplicates. In addition, since they are not all allowed in all contexts, we check and give diagnostics if an DeclModifier appears where it is not allowed.
