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.

mapi/glapi: Use ElementTree instead of libxml2.

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
one method for each kind of object to be created, as it simplifies

i965: Fix compiler warning about signed/unsigned.

Reviewed-by: Kenneth Graunke <kenneth@whitecape.org>

i965/gen8: Change the winsys MSAA blits from blorp to meta.

This gets us equivalent code paths on BDW and pre-BDW, except for stencil
(where we don't have MSAA stencil resolve code yet)

Improves MSAA-forced citybench by 7.94496% +/- 2.38429% (n=16).  Reduces
DRI2 MSAA glxgears performance by -12.3559% +/- 1.52845% (n=9).

v2: Move the new meta code to brw_meta_updownsample.c, name it
    brw_meta_updownsample(), add a comment about
    intel_rb_storage_first_mt_slice(), and rename that function and move
    the RB generation into it (review ideas by Ken).
v3: Fix 2 src vs dst pasteos in previous change.
v4: Skip this path pre-gen8 for now, until we can analyze the glxgears
    performance delta some more.
