In all these cases, any rendering implied by this damage has already
occurred, and we want to get the damage out to the client. Some of
the DamageRegionAppend calls were explicitly telling damage to flush
the reportAfter damage out, but not all.
Bug #30260. Fixes the compiz wallpaper plugin with client damage
changed to reportAfter.

Previously we assumed every pixmap destroyed during a software fallback was
also created during a software fallback and had access prepared, but that's
not always true.

This patch only changes the API, not the implementation of the
devPrivates infrastructure. This will permit a new devPrivates
implementation to be layed into the server without requiring
simultaneous changes in every devPrivates user.

This is a combination of a huge mechanical patch and a few small
fixups required to finish the job. They were reviewed separately, but
because the server does not build without both pieces, I've merged
them together at this time.
The mechanical changes were performed by running the included
'fix-region' script over the whole tree:
$ git ls-files | grep -v '^fix-' | xargs ./fix-region
And then, the white space errors in the resulting patch were fixed
using the provided fix-patch-whitespace script.
$ sh ./fix-patch-whitespace
Thanks to Jamey Sharp for the mighty fine sed-generating sed script.
The hand-done changes involve removing functions from dix/region.c
that duplicate inline functions in include/regionstr.h, along with
their declarations in regionstr.h, mi.h and mispans.h.

The only remaining X-functions used in server are XNF*, the rest is converted to
plain alloc/calloc/realloc/free/strdup.
X* functions are still exported from server and x* macros are still defined in
header file, so both ABI and API are not affected by this change.

Only return TRUE if the GPU copy is being accessed, and preserve the return
value on repeated / nested calls for the same pixmap.
exaPrepareAccessReg_mixed could get inconsistent return values e.g. when the
same pixmap is both the destination and source of an operation, potentially
resulting in a crash.

If there are several software fallbacks affecting the system memory copy of the
same pixmap, only copy the results back to the driver pixmap when it's used for
acceleration again, or in the BlockHandler, whichever happens first.
If the PrepareAccess hook fails, use the DownloadFromScreen hook to retrieve
driver pixmap contents to a system RAM copy, perform software rendering on that
and copy the results back using the UploadToScreen hook. Use the classic
migration logic to minimize transfers (which as a bonus allows slightly
cleaning up some of the existing mixed pixmap code).
This enables things that weren't possible before with driver-allocated pixmap
storage: If some (or all) GPU pixmap storage can't be mapped directly by the
CPU, this can be handled between the PrepareAccess and
DownloadFrom/UploadToScreen hooks, e.g.:
* Radeon KMS on big endian machines can fail PrepareAccess if the pixmap
requires byte-swapping and swap bytes in DownloadFrom/UploadToScreen.
* Environments where GPU and CPU don't have a shared address space at all.
Here the driver PrepareAccess hook will always fail and leave all transfers
between GPU / CPU storage to the Download/From/UploadToScreen hooks.
Drivers which can handle all pixmaps in the PrepareAccess hook should notice
little if any difference.
- Based on driver pixmaps with some changes (completely transparent to driver).
- It helps with the problem of known software fallbacks, such as trapezoids.
- exaDoMigration is now called for all cases that provide a do_migration hook.
- exa_migration.c is renamed to exa_migration_classic.c
- Create a few seperate functions and a few private function pointers.
- Replace a few if conditions with a check for pExaPix->pDamage instead.
- This is in preperation of a third scheme that lies somewhere in between.
- Code clarity would have suffered (i started working on it and didn't like the mess).
Use reference counting and do nothing unless the reference count transitions
to/from 0.
Fixes https://bugs.freedesktop.org/show_bug.cgi?id=22822 .
As a bonus, this avoids calling the driver Prepare/FinishAccess hooks more than
once per pixmap and operation.
Also update the Doxygen documentation for the PrepareAccess driver hook to
better match current reality.
At most once per second, under the following circumstances:
* We can't satisfy an offscreen memory allocation, but there seems to be enough
offscreen memory available in total.
or
* The server has been idle for at least 100ms, and there is more than one
available offscreen area.

- fbChangeWindowAttributes can create pixmaps (and access them) without use preparing access.
- Also handle the destroyed pixmaps by finishing them first.
- Switch to DEST indices again in exaCreatePixmapWithPrepare, because they are obviously being rendered to.
- Also avoid calling FinishAccess on pixmaps that are destroyed (and their memory potentially invalid).
- In a previous patch i forgot to add a FALSE somewhere it seems.
- Rename AUX indices so the driver (think of driver managed pixmaps) can do optimisations based upon them.
- Fix one abuse of DEST index now that we have the AUX indices (same reason as above).
Preserve the EXA ABI by introducing a new driver flag EXA_SUPPORTS_PREPARE_AUX.
If the driver doesn't set this flag, we have to assume any Prepare/FinishAccess
driver hooks can't handle the EXA_PREPARE_AUX* indices, so we move out such
pixmaps at PrepareAccess time.

- The src optimisation is more aggressive and possibly harmful in light of the new initial state of pixmaps.
- There is now actually a performance improvement by almost always keeping the number of rects low.
- use DEST in the createPixmap wrapper, because stipple already takes MASK (in case someone uses swappers).
- Anticipate some of the less common situations when fbValidateDrawable will access tile related pixmaps.
