To make things really better we should track the line origin of
element from the .gir file (and actually we need to do better
checking in the scanner), but this is slightly less lame.
Rather than having bindings use g_function_info_invoke, which is basically
a toy/demo API, export a convenience utility function which takes the introspection
information and sets up things we need to pass to libffi.
Then invocation can be done directly to libffi by a binding.
As part of this work, remove some (unused by gjs) public functions from the
girffi API, and instead export a function to map to libffi which can work
semi-correctly.

The scanner misses all fields of the GObject struct -- there
are no <field> children of the <class> element for GObject in the GIR. This of
course yields wrong field offsets for all derived objects.

Arrays are currently not handled specially, and hence treated as pointers in
giroffsets.c:get_field_size_alignment(), which is (obviously) wrong.

In order to set and get enum and flag fields in structures, we need
to know the integral type that the enumeration is stored as. We are already
computing that at compile time in order to compute struct offsets, so the
easiest thing to do is to save that in the typelib.

girepository/gtypelib.h: Add 'storage_type' to the typelib format for EnumBlob
and compute and save it at compile time.

Add g_enum_info_get_storage_type().

based on the storage type.

Compute field offsets and overall size for object structures
Bug 560326 – Fails to build Gtk-2.0.typelib with "Unexpected non-pointer
field of type object in structure"
Do basic computation of field offsets for objects and interfaces;
this doesn't attempt to address all of the "mess" for virtual
functions described in Bug 560281.
