This reverts commit 1564c82417.
The drivers used the top bits of the usage_hint to store driver
private flags (intel, radeon, nouveau).
With EXA we need to get at this data so if we migrate the pixmap we
can create the correct type of pixmap in the driver, however this
commit truncates the usage_hint into 8-bit class and loses all the
good stuff.

If there's a GPU copy and a non-zero devKind was passed in, set the GPU copy
pitch to that instead of to a possibly bogus value derived from the new width.
This is e.g. used by the radeon driver's drmmode_xf86crtc_resize hook, fixes
https://bugs.freedesktop.org/show_bug.cgi?id=33929 .
On the other hand, the system memory copy doesn't need the pitch to be aligned
beyond the PixmapBytePad of the width.

- It turns out that the high latency was a driver problem.
- catting a large amount of text turns out to look prettier when the
throughput is lower, but it's not worth the loss for a minor
improvement that may not even exist on someone else's computer.

- Apps like xterm can trigger a lot of fallback rendering.
- This can lead to (annoyingly) high latencies, because you
have to wait for the block handler.
- You need a driver that doesn't directly access the front
buffer to trigger this (NV50+ nouveau for example).
- Repeatingly doing dmesg on an xterm with a bitmap font
will reveal that you never see part of the text.
- I have recieved at least one complaint in the past of slow
terminal performance, which was related to core font
rendering.
- This does sacrifice some throughput, roughly 33% slower.

In case you want to copy a region with source = dest, you have the same pixmap
as source and dest.
At the end of exaPixmapIsOffscreen_classic() the devPrivate.ptr is reset to
NULL (look at the sources).
Now this is what happens in ExaCheckCopyNtoN:
exaPrepareAccess( pDst );
Calls IsOffscreen()
sets devPrivate.ptr to NULL
sets up devPrivate.ptr to real pointer
Everything OK
exaPrepareAccess( pSrc );
Calls IsOffscreen()
sets devPrivate.ptr to NULL
BAILS OUT CAUSE OF NESTED OPERATION SINCE DST EQUALS SRC
We end up with devPrivate.ptr as NULL, and that is clearly wrong.
In particular this fixes a segfault when using the psb driver (bug 28077)

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.
