bind: accept null objects as nil pointers

Currently the generated bindings assume that any object
passed to Go as a method argument is actually a valid one
originating from Go. The `null` object is however a corner
case to this assumption, which should be accepted for Go
pointer types, since they can cleanly convert into `nil`.

This CL modifies the generated wrapper code so any `nil`
reference is permitted for Go pointer types, which until
now produced a nil pointer dereference error.

Fixes golang/go#20330

Go support for Mobile devices

The Go mobile repository holds packages and build tools for using Go on mobile platforms.

Package documentation as a starting point:

Caution image

The Go Mobile project is experimental. Use this at your own risk. While we are working hard to improve it, neither Google nor the Go team can provide end-user support.

This is early work and installing the build system requires Go 1.5. Follow the instructions on to install the gomobile command, build the basic and the bind example apps.

Contributions to Go are appreciated. See
