dix: Allow zero-height PutImage requests (fix for X.Org's CVE-2015-3418).

The length checking code validates PutImage height and byte width by
making sure that byte-width >= INT32_MAX / height. If height is zero,
this generates a divide by zero exception. Allow zero height requests
explicitly, bypassing the INT32_MAX check.
Fix for regression introduced by fix for CVE-2014-8092.

ArcticaProject/PR-ionic/libXinerama_symlink_to_libnx-xinerama1
debian/libnx-xinerama1.*: also create libXinerama symlink in libnx-xinerama1.postinst (and remove in libxinerama1.prerm).

prerm.)
Due to the nx-x11-common package being a noarch/allarch package,
creating the symlink in nx-libs' Makefile will lead to the symlink
referencing the "default" architecture dpkg uses for building
noarch/allarch packages.
Incidentally, this worked fine for Debian, as amd64 seems to be the
default architecture. On Ubuntu, however, the default architecture up to
Vivid (15.04) was i386. For those builds, the symlink pointed to the 32
bit library of libNX_Xinerama.so.1 -- essentially breaking this feature.
Move the symlink creation to the arch-sensitive libnx-xinerama1 package.
The postinst and prerm scriptlets will work fine, unless someone
installs the i386 package version *after* the amd64 version. Given that
we already create symlinks to libNX_X11 and friends using that method,
no new regression is introduced. Strictly speaking that's a bug, but
we'll hopefully clean that up later...

CVE-2013-7439).
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.

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).

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
