egl/x11: advertise __DRI_USE_INVALIDATE for DRI2

Back in 2012 (commit 1e7776ca2bc - egl: Remove bogus invalidate code.)
the loader use of invalidate() was purged as "bogus". One of the factors
defining that statement was the lack of the loader-side invalidate
extension - __DRI_USE_INVALIDATE.

Since then the commit was reverted (commit eed0a80137d - egl: Restore
"bogus" DRI2 invalidate event code.), always performing the driver
invalidate call, although the loader was never updated to expose the
extension.

Do so allowing the driver to do fine grained tuning.

i965: Fix state flagging of Gen6 SOL programs.

It doesn't seem like the old code could possibly work.

1. brw_gs_state_dirty made us bail unless one of these flags were set:
   _NEW_TEXTURE, BRW_NEW_GEOMETRY_PROGRAM, BRW_NEW_TRANSFORM_FEEDBACK
2. If there was no geometry program, we called brw_upload_ff_gs_prog()3
3. That checked brw_ff_gs_state_dirty and bailed unless these were set:
   _NEW_LIGHT, BRW_NEW_PRIMITIVE, BRW_NEW_TRANSFORM_FEEDBACK,
   BRW_NEW_VS_PROG_DATA.
4. brw_ff_gs_prog_key pv_first and attr fields were set based on data
   depending on _NEW_LIGHT and BRW_NEW_VS_PROG_DATA.

This means that if we needed a FF GS program, and changed the VS
outputs or provoking vertex mode, we'd fail to notice that we needed
to emit a new program.

We can drop the meaningless "64" suffix - libdrm_intel originally had

and we couldn't remove/alter that field without breaking ABI, so we had
to add a uint64_t "offset64" field.

"gtt_offset" is also more descriptive than "offset".

Accompanying patch "st/mesa: only try to create 1x msaa surfaces for
'fake' msaa" requires driver to report max_samples=1 to enable "fake"
msaa. Previously, 0 and 1 were treated equivalently in st_init_extensions()
and either could enable "fake" msaa.

This patch raises the swr default msaa_max_count from 0 to 1, so that
swr_is_format_supported will report max_samples=1.

Real msaa can still be enabled by exporting SWR_MSAA_MAX_COUNT with a
pow2 value between 2 and 16.

This patch is necessary to prevent an OpenSWR regression resulting from
the st/mesa patch.
