a136ca65ea Allow functions without parameters
- Fixed: Trying to define a function without any parameters would silently
  discard the function, because the declarator tested FuncParams instead
  of FuncName to decide if it was a function.

0d25ed8289 state_call needs parenthesis around func_expr_list
- Fixed: state_call needs to enclose func_expr_list in LPAREN/RPAREN
  itself, because func_expr_list doesn't include them. This means it also
  needs a separate production to accept calls without a parameter list.

46c0127ebb Don't accept function params starting with a comma
- Fixed: func_expr_list would accept nonsense like this:
    Myfunction(, 1, 2);

733e5fa2e1 Recognize C-style array declarations
- The variable_name production now accepts an optional array size
  argument. (Not yet passed to the AST.)
- The notation for using dotted ID lists as types has been changed from
  [id1.id2] to .id1.id2, beacuse the former conflicts with the notation
  for arrays.

2d139f3846 - DoParse() now writes out the parsed AST for the input file to <file>.ast.
Maybe TODO: Find a simple LISP pretty printer that isn't written in LISP so that the output
  isn't all on one big long line.
- zcc-parse.lemon now returns the complete AST through the parse state.
- Fixed crash in PrintEnumNode().

4b8900816b - Make the ZCC parser compilable again. Does every rule in the grammar that needs to appear in
the AST do so now? That would sure be nice.

081ebbb64b - I have decided to opt for simplicity over C-like-ness and group array sizes with the rest
of the type declaration rather than split it up after the variable name.
- More AST work. At this rate, maybe I'll finally be building a complete AST by the end of the
  month!

c043627cc1 - Some abstract syntax tree creation stuff. (Plus some tentative type creation stuff that made
me realize I would be better off creating a type-agnostic AST for the entire input instead
  of trying to tentatively create types before they're seen.)
