mesa: Allow setting GL_TEXTURE_MAX_LEVEL to 0 with GL_TEXTURE_RECTANGLE.

Currently, we raise an error when doing this which breaks a conformance
test from the OpenGL samples pack. Even if this is a bit silly it is not
an error.

From http://www.opengl.org/wiki/Rectangle_Texture:

"Rectangle textures contain exactly one image; they cannot have mipmaps.
Therefore, any texture parameters that depend on LODs are irrelevant
when used with rectangle textures; attempting to set these parameters to
any value other than 0 will result in an error."

This is hella ugly.  The same-named function in desktop OpenGL is
hidden, but it needs to be exposed by libGLESv2 for OpenGL ES 3.0.
There's no way to express in the XML that a function should be be hidden

st/mesa: overhaul texture / sample swizzle code

Previously we only examined the GL_DEPTH_MODE state to determine the
sampler view swizzle for depth textures.  Now we also consider the
texture base format for color textures too.

The basic idea is if we're sampling from a RGB texture we always
want to get A=1, even if the actual hardware format might be RGBA.
We had assumed that the texture's A values were always one since that's
what Mesa's texstore code does.  But if we render to the RGBA texture,
the A values might not be 1.  Subsequent sampling didn't return the
right values.

Now we examine the user-specified texture base format vs. the actual
gallium format to determine the right swizzle.

Fixes several fbo-blending-formats, fbo-clear-formats and fbo-tex-rgbx
failures with VMware/svga driver (and possibly other drivers).
No other piglit regressions with softpipe or VMware/svga.

It is quite hard to meet the dependency of the libxml2 python bindings
outside Linux, and in particularly on MacOSX; whereas ElementTree is
part of Python's standard library.  ElementTree is more limited than
libxml2: no DTD verification, defaults from DTD, or XInclude support,
but none of these limitations is serious enough to justify using
libxml2.

In fact, it was easier to refactor the code to use ElementTree than to
try to get libxml2 python bindings.

In the process, gl_item_factory class was refactored so that there is
