* generator/ObjectGen.cs : Add IntPtr constructor generation. Pass a
ctor signature hash around to use in clash resolution. Generate a
void ctor if none is present which just calls the parent ctor.
* generator/StructBase.cs : Add non-void signature ctor generation,
including collision handling logic. Collisions are implemented as
static methods.
* generator/SymbolTable.cs : Map GSList to GLib.SList. Add type
trimming to remove trailing *'s. Need to suppress leading const yet.
* glib/Object.cs : Add default ctor for void and IntPtr ctors.
* glib/SList.cs : Implementation of a wrapper class for GSLists. Lots
of FIXMEs.
* parser/gapi2xml.pl : Handle ** and array params.
