e8c73ac697 Xephyr: fix compilation breakage.
* hw/kdrive/ephyr/ephyr_draw.c:
          (exaDDXDriverInit): pExaScr->hideOffscreenPixmapData does not exist
          anymore, so don't set it.

3d4ca57b69 Add a helper for the Component Alpha Over case, which breaks the operation
down into an OutReverse and an Add. Turn off the fallback to software
    glyphs when component alpha, now that we expect all (new) drivers to be
    able to support it. Also, make Xephyr fall back in the CA Over case to
    exercise this code. This speeds up my rgb24text and ls -lR in
    gnome-terminal by a factor of 5.

074dc9a023 Add an option to verify at the point of migration that pixmaps which aren't
marked dirty are in fact not dirty. This will hopefully help catch
    issues like the previous commit. Leave it on in fakexa.

c947d796aa Missed in previous commit: Add a new migration scheme, called "Smart" for
lack of a better name. This one behaves somewhat between Greedy and
    Always. It moves in if we can accelerate, unless the destination is
    clean and shouldn't be kept in framebuffer according to the score, in
    which case we migrate out (and force-migrate anything where migration
    is free). This should help fix lack of acceleration for drivers without
    UTS since removing exaAsyncPixmapGCOps, and has removed one performance
    trap with Radeon I'd noticed. It is the new default.

2e38fedd29 Add an option to EXA for the DDX to request that EXA hide the pixmap's
devPrivate.ptr when pointing at offscreen memory, outside of
    exaPrepare/FinishAccess(). This was used with fakexa to find (by NULL
    dereference) many instances of un-Prepared CPU access to the
    framebuffer:
- GC tiles used in several ops when fillStyle == FillTiled were never
    Prepared.
- Migration could lead to un-Prepared access to mask data in render's
    Trapezoids and Triangles
- PutImage's UploadToScreen failure fallback failed to Prepare.

3cf46cc1e3 Add an UploadToScreen implementation, for testing PutImage support, and
make the DownloadFromScreen more robust.

4bb5ab0b44 Add a DownloadFromScreen implementation, used for testing GetImage
acceleration, and set the migration scheme to Always on init (since
    this is all for testing, and Always should make migration happen more
    frequently than Greedy).

d695579848 If fakexa is enabled, create a larger buffer in the Ximage, but keep the
same width/height for front-buffer drawing. The fakexa code then uses
    this extra space for offscreen pixmaps. Note that this tones down the
    absurdity of fakexa's offscreen pixmap alignment requirements (odd
    alignment is too weird, so stick with "24", which is still strange but
    exists out there). It also fixes a couple of bugs in the fakexa
    implementation revealed by using offscreen pixmaps.

2822cbc1fb Rearrange EXA driver structures so that there's a hope of maintaining ABI
when extending the driver interface. The card and accel structures are
    merged into the ExaDriverRec, which is to be allocated using
    exaDriverAlloc(). The driver structure also grows exa_major and
    exa_minor, which drivers fill in and have checked by EXA
    (double-checking that the driver really did check that the EXA version
    was correct). Removes exaInitCard(), which is replaced by the driver
    filling in the rec by hand, and the exaGetVersion() and related
    EXA_*VERSION which are replaced by always using the XFree86 loadable
    module versioning.

9d8c0e4bcb Add a new flag to ephyr, "-fakexa", which turns on an EXA acceleration
implementation that calls fb to get its work done. The purpose is to
    have a trusted EXA driver for use with testing changes to the core of
    EXA. However, fakexa has not received much testing yet, lacks offscreen
    pixmaps support, and doesn't reliably provide garbage when EXA doesn't
    get its syncing right. All of these should be fixed soon.
