* Convert the GCHandles interface from 32-bit ints to pointer size types
This involves:
* Stop using some bits of the GCHandle to store extra flags, instead add an extra
field to store those flags.
* Define a INVALID_GCHANDLE constant and use it instead of 0/NULL. This is not
strictly required, but it makes the code more self-documenting.
* Define a GCHandle type (typedef'ed to void*) and change all variables and parameters
to use it instead of guint32.
* Use our own xamarin_gchandle_* methods (with pointer-sized types) that wraps
the mono_gchandle_* embedding API (which uses 32-bit types) everywhere.
* Update managed code (registrars, runtime code, etc) accordingly.
* [runtime] Make debug code compile.
* Fix typo.
* Fix signature of xamarin_create_gchandle.

* [runtime] Add an inner exception parameter to Runtime.CreateProductException.
This allows us to simplify code by using inner (and outer) exceptions as
a means to provide information instead of passing extra information
around in order to create decent exceptions.
One example is how we pass the selector and method name to the method
that converts from a native id to a managed NSObject instance: passing
this information is not necessary anymore if we can use two exceptions,
one for the failure to convert from an id to a NSObject instance,
wrapped in a second that tells which method/selector call ran into this
conversion problem.
* [runtime] Throw better exceptions when the dynamic registrar can't marshal something.
* [runtime] Throw a better exception when something goes wrong when trying to marshal a return value.
* [runtime] Use inner exceptions to convey failure information instead of trying to create a single exception with all we know.
* Fix merge problem.
