[Intel-gfx] [ANNOUNCE] xf86-video-intel: snapshot (now with 10% reduced fat!)

This is a development snapshot very early in the process toward
developing 2.8. There have been some big changes to the code, and
we're anxious to get feedback on these changes as early as possible.

Here is a summary of the biggest changes:

  * Driver now depends on X server 1.6 or later

  * Eliminate XAA and EXA support (in favor of UXA)

  * Eliminate DRI1 support

  * Fixes for running without DRI at all

These code removals represent a deletion of a substantial amount of
code, (and hopefully piles of bugs), as well as reduce the maintenance
effort going forward as the number of combinatorial configurations for
the driver are greatly reduced. This means that users are much more
likely to be running code that has actually been tested, and it will
be much easy for developers to replicate bugs that users experience.

Many thanks to Eric Anholt for gutting so much code! And see Keith
Packard's writeup describing the benefits of this code removal:


One of the things that would be most useful in testing this release is
to revisit any outstanding bugs that you have previously reported. If
the buggy behavior is gone, (or the bug is no longer relevant---such
as a bug that's specific to XAA only), please feel free to indicate so
in bugzilla or even just close the bug.

If you confirm that the bug is still present, please indicate so in
the bug report. (I was going to ask that you select a 1.7.99 version,
but it looks like bugzilla only has versions for products not
compoenents, while we use a "xorg" product and a "driver/intel"
component.) We definitely want to make any such confirmed bugs a
priority, so it would be nice to have a consistent mechanism to search
for these bugs. Suggestions are welcome on the best approach.

Thanks in advance for any testing or feedback on this snapshot.
