nx-libs.spec: Drop packaging of libNX_Xpm*, in RPM packages there is no such concept for transitional/dummy packages as know from Debian/Ubuntu.

arch cleanup (CRAY/WORD64) + X.Org CVE-2013-7439

Attributes GH PR #13: https://github.com/ArcticaProject/nx-libs/pull/13

 NX agent contains/ed two build trees. An old one (probably pre-3.x.y)
 and a "newer" one. The "newer" code tree used to become enabled by
 setting NXUpgradeAgentServer in nx-X11/config/cf/host.def to YES.

 As building the NXUpgradeAgentServer has been the default for
 years now, we drop all code that does not get used at build time
 for NXUpgradeAgentServer == YES (i.e., the code that belongs to the
 pre-3.x.y phase of NX agent).

 MakeBigReq inserts a length field after the first 4 bytes of the request
 (after req->length), pushing everything else back by 4 bytes.

 The current memmove moves everything but the first 4 bytes back. If a
 request aligns to the end of the buffer pointer when MakeBigReq is
 invoked for that request, this runs over the buffer. Instead, we need to
 memmove minus the first 4 bytes (which aren't moved), minus the last 4
 bytes (so we still align to the previous tail).

 The 4 bytes that fell out are already handled with Data32, which will
 handle the buffermax correctly.

 The case where req->length = 1 was already not functional.

old-arch cleanup: Drop CRAY support (i.e., drop code related to CRAY, _CRAY, WORD64, WORD64ALIGN, MUSTCOPY, UNSIGNEDBITFIELDS definitions).

 Launch this script (after nxproxy has been installed into $PATH) and you
 will be able to evoke any local command through a

    nxproxy -C <-> nxproxy -S

 connection on DISPLAY=:8.

 This eases testing NX compression without using NX agent on the server
 side.

 How to use:

    # install nxproxy into $PATH, then...
    $ cd doc/examples/
    $ ./run-nxproxy2nxproxy-test
    $ export DISPLAY=:8
    $ xterm

This is basically a merge of the most current xorg-server (1.17.1) code
into nx-X11.

It makes sure that for source pictures, which do not have a drawable
surface, a filter is selected that is supported on the "main" and all
other screens.  Alternatively, if the requested filter is not available
on all screens and the picture is a source picture, this function fails
gracefully.

Additionally, the ChangePictureFilter hook is now called for non-source
pictures.

This also needs an implementation in mipict.{c,h}. The default hook does
nothing and returns a success value.

nxcomp{,ext,shad}: only use the first three numbers in the full version for current_version on OS X. ld(1) on 10.6 fails otherwise.

nxcomp{,ext,shad}: use the correct library naming scheme on OS X. It differs from other UNIX-based systems.
