gl: enable use of buffer objects for TexSubImage2D by nil

This CL enables use of a bound buffer at TexSubImage2D by allowing
nil (0) data, which indicates the head of the bound buffer.

In the long run, we need to be able to pass non-0 integer to not
only TexSubImage2D but also other functions like TexImage2D. As we
might change the API, let's revisit this issue later.

Fixes golang/go#36355

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 golang.org/wiki/Mobile to install the gomobile command, build the basic and the bind example apps.
