properties can't be set until Validate-time (eg, Method.IsGetter), but it's annoying for every potential user of those properties to have to make sure it has Validated the generatable first. So now we add an explicit Validate() step after everything is loaded but before anything is Generated, so that at Generation time, everything can be assumed to have been Validated. * generator/IGeneratable.cs: add "bool Validate()" * generator/CodeGenerator.cs (Main): after loading all of the generatables, DeAlias the SymbolTable, Validate() all the generatables, and discard any invalid ones. * generator/*.cs: Implement Validate() trivially in generatables that didn't implement it before. Move Validate() calls from Generate() to Validate(). Remove non-hierarchical Validate() calls. * generator/SymbolTable.cs: GPtrArray is IntPtr, not IntPtr[] svn path=/trunk/gtk-sharp/; revision=48046
