It should be possible to query the number of primitives written to each
individual stream by a geometry shader in a single draw call. For that
we need to have up to MAX_VERTEX_STREAM separate query objects.

So far we have been using CL_INVOCATION_COUNT to resolve this query but this
is no good with streams, as only stream 0 reaches the clipping stage. Instead
we will use SO_PRIM_STORAGE_NEEDED which can keep track of the primitives sent
to each individual stream.
Since SO_PRIM_STORAGE_NEEDED is related to the SOL stage and according to
ARB_transform_feedback3 we need to be able to query primitives generated in
each stream whether transform feedback is active or not what we do is to
enable the SOL unit even if transform feedback is not active but disable all
output buffers in that case. This effectively disables transform feedback
but permits activation of statistics enabling SO_PRIM_STORAGE_NEEDED even
when transform feedback is not active.

If the geometry shader is indeed using streams then we need 2 control data

On Intel hardware when a geometry shader outputs GL_POINTS primitives we
only need to emit vertex control bits if it emits vertices to non-zero
streams, so use a flag to track this.
This flag will be set to TRUE when a geometry shader calls EmitStreamVertex()
or EndStreamPrimitive() with a non-zero stream parameter in a later patch.

While the official INTEL_swap_event specification says that the drawable
field should contain the GLXDrawable, not the Drawable, the existing
DRI2 code in dri2.c that translates from DRI2_BufferSwapComplete sends out
GLX_BufferSwapComplete with the Drawable's ID, so existing codebases
like Clutter/Cogl rely on getting the Drawable.
Match DRI2's error here and stuff the event with the X Drawable, not
the GLX drawable.
This fixes apps seeing wrong drawables through an indirect GLX context
or with DRI3, which uses the GLX_BufferSwapComplete event directly on
the wire instead of translates Present in mesa.
At the same time, also modify the structure for the event to make sure
that clients don't make the same mistake. This is not an API or ABI
break, as GLXDrawable and Drawable are both typedefs for XID.
