The ANGLE_multiview specification is modified so that Draw* generates
an error if the number of views in the active program does not match
with the number of views in the active draw framebuffer object.
The tests and validation are modified accordingly.

The patch also sets a contact person, updates the contributor list and
sets the correct enum values in the ANGLE_multiview specification.

There were a few calls that were using the context directly.
Consolidating them in the StateManager11 class should make efficient
state update after a Context switch possible. Also remove the Context
parameter from the setRenderTargets methods, since these are only
used internally and should be dirtying other states themselves.

This also changes the dirty TF object to use a Serial, which is more
secure for very edge-care reallocation issues. It also moves the
StateManager11::updateState call to be the very first thing that
happens in a draw call. This prepares the back-end for making the
state sync actually happen in Context11::syncState, instead of
inside the draw call.

Also moves a bit more TF management code out of RendererD3D and

Any time we would query ProgramD3D for a particular vertex or pixel
shader, we would iterate over all the cached shaders of the program
looking for the matching input or output layout signature. This change
makes it so we only compute the index of the matching shader once,
and subsequent calls will re-use the shader index. This should speed
up the draw call benchmarks.

Also include a fix to the Serial class that initializes a Serial value
to an invalid sentinel value. This ensures that comparing any other
Serial (including another invalid serial) to the invalid serial will
return not-equals.
