Merge branch 'bind-memory-early' into 'master'

Bind memory early

The consensus in https://cvs.khronos.org/bugzilla/show_bug.cgi?id=13095 seems to be that clients should bind memory prior to using the image or buffer for anything.  In particular, they should bind memory prior to creating views.  In our implementation, we generate an actual hardware packet with an address in it at view creation time.
