As we don't have yet a proper way of negotiating a common protocol
version to use between clients and the server, we introduce a command
without reply arguments that allows us to figure out if the server is
new enough to handle negotiation of the protocol version.

In 4732489 (shader: do not redeclare built-ins as precise), I confused a
mesa shader-compiler bug with a spec problem. Turns out, redeclaring
built-ins as precise is allowed by the spec, just the same as invariant
variables. And even mesa allows this.
What mesa doesn't currently allow, is to redeclare a variable as *both*
invariant *and* precise. This problem does not extend to new
declarations, where this is already handled correctly.
So, let's avoid emitting both; it's not really needed to emit both, as
they essentially have the same effect (disable reordering), just with
some different usage-semantics. And for the cases we support, these are
effectively the same.

When enabling/disabling GL_BLEND via vrend_blend_enable the context
cached the last state and doesn't call glEnable/glDisable if the state
didn't change. However, when gl(Enable|Disable)IndexedEXT is used with
index 0, then this vrenderer internal state is not updated even though
the corresponding GL state may be changed, and calling vrend_blend_enable
later may not update the actual OpenGL state correctly.
In order to avoid this and to simplify the setting the blend enabled state
remove the caching and always call glEnable/glDisable directly.

In 47387e4 (emit precise keyword), I added code to try to declare
outputs as 'precise' if an instruction flagged as precise wrote to it.
Turns out, redeclaring built-ins as 'precise' isn't allowed, so that bit
was a mistake. And because mesa transforms "invariant" into instructions
with the precise-flag set, we can end up writing to built-ins with the
precise-flag, leading to shaders that doesn't compile correctly.
So let's remove the code that emits the precise-keyword when re-declaring
built-ins.

The vertex shader always gl_PerVertex, but the tesselation shaders only
define the structure when the point size extension is enabled, otherwise
gl_PointSize is passed as a generic varying and can not be written to.
If one enables the extension based on whether the value gl_PointSize is
actually accessed in the tess shaders then it might happend that tess_ctrl
doesn't touch the value, and the extension isn't enabled, and tess_eval
accesses it and the extension is enabled. In such a case gl_PointSize is
passed as a generic to and from the tess_ctrl shader and linking of the
shaders will fail because of different definitions of gl_PerVertex.
Since in this case there is no indication in the tess_ctrl shader that
point_size is accessed, and it is not known whether the shader will be
linked with a tess_eval shader that uses gl_PointSize the workaround is to
always enable the extension for all tesselation shaders.
