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.

When we blit data into a buffer object, we may need to invalidate any

While this flushing was missing, it usually happened implicitly for

intel_emit_linear_blit() would require switching to the BLT ring,

Revert "egl: Allow creation of per surface out fence"

This reverts commit 13c23b19d0b3b965d666498eb759e63fc4a625d9.

Mesa CI was brought down by this commit, with:

mesa/drivers/dri/i965/brw_sync.c:491: brw_dri_create_fence_fd:
Assertion `brw->screen->has_exec_fence' failed.

For Gen8, add 2xMSAA. For Gen9, add 2xMSAA and 16xMSAA.
Special thanks to Eero Tamminen for reporting rasterizer

Revert "i965: add 2xMSAA and 16xMSAA to DRI configs for Gen9."

This reverts commit f6d38785e8b28a6dd303884798b823e289817741.

Kevin's original patch accidentally didn't add 2x for Gen8; he sent
a v2 with a bunch of style fixes shortly after I pushed the original
patch, not knowing it was coming.  Let's just revert this one, apply
v2, and move on.

egl: Allow creation of per surface out fence

Add plumbing to allow creation of per display surface out fence.

Currently enabled only on android, since the system expects a valid
fd in ANativeWindow::{queue,cancel}Buffer. We pass a fd of -1 with
which native applications such as flatland fail. The patch enables
explicit sync on android and fixes one of the functional issue for
apps or buffer consumers which depend upon fence and its timestamp.

v2: a) Also implement the fence in cancelBuffer.
    b) The last sync fence is stored in drawable object
       rather than brw context.
    c) format clear.

v3: a) Save the last fence fd in DRI Context object.
    b) Return the last fence if the batch buffer is empty and
       nothing to be flushed when _intel_batchbuffer_flush_fence
    c) Add the new interface in vbtl to set the retrieve fence

v3.1 a) close fd in the new vbtl interface on none Android platform

v4: a) The last fence is saved in brw context.
    b) The retrieve fd is for all the platform but not just Android
    c) Add a uniform dri2 interface to initialize the surface.

v4.1: a) make some changes of variable name.
      b) the patch is broken into two patches.

v4.2: a) Add a deinit interface for surface to clear the out fence

v5: a) Add enable_out_fence to init, platform sets it true or
       false
    b) Change get fd to update fd and check for fence
    c) Commit description updated

v6: a) Heading and commit description updated
    b) enable_out_fence is set only if fence is supported
    c) Review comments on function names
    d) Test with standalone patch, resolves the bug

v6.1: Check for old display fence reverted

v6.2: enable_out_fence initialized to false by default,
      dri2_surf_update_fence_fd updated, deinit changed to fini
