  Store uniform block bindings in program binaries.
  
  This affects all back-ends - we weren't saving this. Note that
  bindings can only be set after program linking. The spec is fairly
  clear in that any programs saved must be loadable and runnable under
  the same set of state, which would include block bindings.
  
  Also add validation for zero binary formats in GetProgramBinary.
  
  Also add a workaround for AMD where the block bindings were not
  applied properly after link, similarly to our original bug.
  
  This CL also includes a few fixups for GLProgram (raii).
