i965: Allow the blorp blit between BGR and RGB

Previously the blorp blitter would only be used if the format is identical or
there is only a difference between whether there is an alpha component or not.
This patch makes it also allow the blorp blitter if the only difference is the
ordering of the RGB components (ie, RGB or BGR).

This is particularly useful since commit 61e264f4fcdba3623 because Mesa now
prefers RGB ordering for textures but the window system buffers are still
created as BGR. That means that the blorp blitter won't be used for the
(probably) common case of blitting from a texture to the window system buffer.

This doesn't cause any regressions in the FBO piglit tests on Haswell. On
Sandybridge it causes the fbo-blit-stretch test to fail but that is only
because it was failing anyway before the above commit and that commit hid the
problem.

glx: Don't crash on swap event for a Window (non-GLXWindow)

Prior to GLX 1.3 there was the glxMakeCurrent() function that took a
single drawable handle. The Drawable could be either a bare XID for a
Window or an XID for a glxpixmap.

GLX 1.3 added glxMakeContextCurrent that takes 2 handles: one for
reading, one for writing. Nowadays the old glxMakeCurrent call is
implemented as a call to glxMakeContextCurrent with the single handle
duplicated.

Because of this it is allowed to use a plain-old Window ID as an
argument to glxMakeContextCurrent, although nobody really documents this
sort of thing. The manpage for the NEW call specifies the arguments as
GLXPixmaps, but the actual code accepts Window XIDs too, and handles
them correctly.

Similarly, the glxSelectEvents function can also take a bare Window XID.

The "piglit" tests all use GLXWindows and/or GLXPixmaps. You never
tested swap events with a bare Window XID. That is what my app was
doing.

The swap_events code worked with Window XIDs in mesa 7.x.y. The new code
added in versions 8, 9, and 10 assumes that all buffer swap events have
a GLXPixmap associated with them. Because of the historical quirks
above, this is not true. Swap events for bare Window XIDs do NOT have a
glxpixmap resulting in a segfault.

Any app that uses the old school glxMakeCurrent call with a Window XID
while trying to use swap_events will crash when the libs try to lookup
the nonexistent GLXPixmap associated with the incoming swap event.

I believe that the people who wrote the spec overlooked this, because
the "sbc" field comes from the OML_sync extension that is defined in
terms of glxpixmaps only.

st/mesa: set sampler_view::last_level correctly

It was set to pipe_resource::last_level and _MaxLevel was embedded in max_lod,
that's why it worked for ordinary texturing. However, min_lod doesn't have
any effect on texelFetch and textureQueryLevels, so we must still set
last_level correctly.

meta: Respect the driver's maximum number of draw buffers

Commit c1c1cf5f9 added infrastructure for saving and restoring draw
buffer state.  However, it universially used MAX_DRAW_BUFFERS, but many
drivers support far fewer than that at limit.  For example, the radeon
and i915 drivers only support 1.  Using MAX_DRAW_BUFFERS causes meta to
generate GL errors.

gallivm: fix SCALED -> NORM conversions

Such conversions (which are most likely rather pointless in practice) were
resulting in shifts with negative shift counts and shifts with counts the same
as the bit width. This was always undefined in llvm, the code generated was
rather horrendous but happened to work.
So make sure such shifts are filtered out and replaced with something that
works (the generated code is still just as horrendous as before).

This fixes lp_test_format, https://bugs.freedesktop.org/show_bug.cgi?id=73846.

mesa: Remove glClear optimization based on drawable size

A drawable size of 0x0 means that we don't have buffers for a drawable yet,
not that we have a zero-sized buffer.  Core mesa shouldn't be optimizing out
drawing based on buffer size, since the draw call could be what triggers
the driver to go and get buffers.  As discussed in the referenced bug report,
the optimization was added as part of a scatter-shot attempt to fix a
different problem.  There's no other example in mesa core of using the
buffer size in this way.

glx: Add an error message when a direct renderer's createScreen() routine fails
because no matching fbConfigs or visuals could be found.

(At the moment, it seems this can be triggered in drisw with an X server which
