Mikhail Gusarov 3f3ff971ec Replace X-allocation functions with their C89 counterparts
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.

Kristian Høgsberg 6d7ba5e0fc dix: Update element count in FreeResource*()
FreeResource() keeps clientTable[cid].elements up to date with the
number of resources allocated to the client.  The other free
resource functions (FreeResourceByType(),
FreeClientNeverRetainResources() and FreeClientResources()) don't
maintain this invariant.

Typically, the only consequence is that the element count is too high
and we end up allocating the hash table bigger than necessary.  However,
FreeResource() also relies on the element count to restart the search if
the list of resources has been changed during a resource destruction
callback.  Since FreeResourceByType() doesn't update the count, if we call
that from a resource destruction callback from FreeResource(), the
loop isn't restarted and we end up following an invalid next pointer.

Furthermore, LookupClientResourceComplex() and
FreeClientNeverRetainResources() don't use the element count to detect
if a callback deleted a resource and may end up following an invalid
next pointer if the resource system is called into recursively.

Dave Airlie 07c36e4fdc dix/resource: fix use after free in resource code with DRI
LookupClientResourceComplex is used by DRI1 code to find and free a DRI
drawable in a callback, however when the DRI code returns this->value
is now pointing at freed memory. It seemed easiest to store the value
to a temporary and return it afterwards.

Another option might be a new FreeClientResourceComplex or one that
also returns the id, so we can free it using an alternative means.

found using valgrind.

amended along ajax's suggestions

Keith Packard f8dd80d13b Replace dixLookupResource by dixLookupResourceBy{Type,Class}
dixLookupResource attempted to automatically detect whether the caller
wanted a lookup by-type or by-class, unfortunately, it guessed wrong for
RT_NONE. Instead of trying to make the guess better, this patch just reverts
the unification and creates separate functions for each operation.

Peter Hutterer 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."

Paulo Cesar Pereira de Andrade 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).

Paulo Cesar Pereira de Andrade 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:
