* art/Makefile.in (clean): Change to avoid bugging out on generated/CVS.
* glib/ObjectManager.cs: Added. Used to be auto-generated, but
now it can infer names, and relies on per-namespace ObjectManager
classes to inform it of oddly-named classes.
* generator/IGeneratable.cs, GenBase.cs: New "DoGenerate" property.
* generator/*Gen.cs: Honor DoGenerate.
* generator/CodeGenerator.cs: Support including dependency files
which will not be generated.
* generator/ObjectGen.cs: Generate mapping file per-namespace, as one
that calls back to the one in glib. Only generate if the name does
not follow the normal conventions, otherwise, GtkSharp.ObjectManager
can infer the name.
* generator/Parser.cs: Accept 'generate' flag to pass on to the
IGeneratables. Parse a new toplevel element, "symbol", which adds
a type to the SymbolTable (instead of hard-coding it).
* generator/SignalHandler.cs: Do not optimize signal handler creation,
instead creating them in their own namespaces. Do not generate
if the calling Signal told us not to.
* generator/Signal.cs: Do not generate handlers if container's DoGenerate
is false. Adjust to the marshaller name being in a sub-namespace.
* generator/SymbolTable.cs (AddSimpleType, AddManualType): Used
to add simple and manually wrapped types at runtime instead of
compile-time.
(FromNative): Remove hard-coded cases for manually wrapped types, use
a generic case instead.
* api: Added. Move api files and generation targets here.
* source: Added. Move source parsing here.
* generator/makefile: Move actual generation to api/.
* glib/Makefile.in: Remove generated/* target.
* glue/Makefile.am: Fix to include canvas-marshal. Move canvas stuff
to GNOME target.
* gnome/CanvasProxy.cs: Update to work with SignalHandlers being
namespace-specific.
* parser/Metadata.pm: Moved to GAPI/Metadata.pm, renamed, etc.
* parser/gapi2xml.pl: Use GAPI::Metadata.
* parser/makefile: Install scripts, remove source parse build target.
Rename formatXML to gapi_format_xml.
