9f0b193acd miDbe window priv priv is pre-allocated, don't use dixSetPrivate (bug 28639)
miDbeInit pre-allocates space in each DBE window private private for a
MiDbeWindowPrivPrivRec. miDbeAllocBackBufferName used the
pre-allocated space correctly (simply fetching it instead of
allocating a new piece of memory). However, it then called
dixSetPrivate anyways, which isn't necessary, and (in the new
dixPrivate world) causes an assert failure.

faeebead7b Change the devPrivates API to require dixRegisterPrivateKey
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.

431781a921 Remove dixRegisterPrivateOffset; hard-code devPrivates offsets instead
For predefined resource types, the offset of the devPrivates field was
already kept in a constant table. The only non-predefined type needing
this treatment was dbeDrawableResType, which is just a magic alias for
RT_PIXMAP.

This patch special-cases looking up RC_DRAWABLE offsets and uses the
table directly for everything else.

1304b8b27c Fix pixmap validation in miDbePositionWindow.
miDbePositionWindow allocates two pixmaps: a front buffer, and a back buffer.
If the buffers are supposed to be initialized, it validates a GC against the
front buffer, then uses it to fill and/or copy both the front buffer *and* the
back buffer, without revalidating.  If the acceleration architecture needs
different GC funcs for the two pixmaps -- for example if allocation of the front
buffer exhausted video memory -- then this can cause crashes because the GC is
not validated for the back buffer pixmap.

Fix this by performing the rendering for the front buffer first, then
revalidating against the back buffer before performing the back buffer
rendering.

cb95642dc8 Remove #define NEED_EVENTS and NEED_REPLIES
A grep on xorg/* revealed there's no consumer of this define.

Quote Alan Coopersmith:
"The consumer was in past versions of the headers now located
in proto/x11proto - for instance, in X11R6.0's xc/include/Xproto.h,
all the event definitions were only available if NEED_EVENTS were
defined, and all the reply definitions required NEED_REPLIES.

Looks like Xproto.h dropped them by X11R6.3, which didn't have
the #ifdef's anymore, so these are truly ancient now."

49f77fff14 Rework symbol visibility for easier maintenance
Save in a few special cases, _X_EXPORT should not be used in C source
files. Instead, it should be used in headers, and the proper C source
include that header. Some special cases are symbols that need to be
shared between modules, but not expected to be used by external drivers,
and symbols that are accessible via LoaderSymbol/dlopen.

  This patch also adds conditionally some new sdk header files, depending
on extensions enabled. These files were added to match pattern for
other extensions/modules, that is, have the headers "deciding" symbol
visibility in the sdk. These headers are:
o Xext/panoramiXsrv.h, Xext/panoramiX.h
o fbpict.h (unconditionally)
o vidmodeproc.h
o mioverlay.h (unconditionally, used only by xaa)
o xfixes.h (unconditionally, symbols required by dri2)

  LoaderSymbol and similar functions now don't have different prototypes,
in loaderProcs.h and xf86Module.h, so that both headers can be included,
without the need of defining IN_LOADER.

  xf86NewInputDevice() device prototype readded to xf86Xinput.h, but
not exported (and with a comment about it).

d6cbd4511e Export symbols defined in the sdk.
This is the biggest "visibility" patch. Instead of doing a "export"
symbol on demand, export everything in the sdk, so that if some module
fails due to an unresolved symbol, it is because it is using a symbol
not in the sdk.

  Most exported symbols shouldn't really be made visible, neither
advertised in the sdk, as they are only used by a single shared object.

  Symbols in the sdk (or referenced in sdk macros), but not defined
anywhere include:
