xorg-server does not follow the convention of using 2 dashes,
and apparently nx-libs doesn't either.

Note that --help does produce the help output. However, it
produces this additional output after it:

Error: NX transport initialization failed.

Therefore, we should instruct users to call -help instead.

It also causes a return code of 1 rather than 0.

Attributes GH PR #44: https://github.com/ArcticaProject/nx-libs/pull/44

COPYING: Replace content with GPL-2 license text, because that is the overall (i.e., strictest) license we have to deal with in nx-libs.

debian/roll-tarball.sh: Rename README.md to README.NX-Development before moving it into doc/ folder.

* bin/{nxagent,nxauth,x2goagent}
* etc/
* doc/nx-X11_vs_XOrg69_patches
* README.keystrokes"
* nx-libs.spec

debian/roll-tarball.sh: Allow patch files names having a dash next to the four digits (i.e., 1234-<patchname>.<suffix>).

 Due to C arithmetic conversion rules we must use an unsigned constant (or a
 cast) to perform the multiplication using unsigned arithmetic.

 Fixes ArcticaProject/nx-libs#55.

Library clean-up: Drop libxkbui, has been built previously but none of its symbols have been used in NX.

Attributes GH PR #40: https://github.com/ArcticaProject/nx-libs/pull/40

imake clean-up: Enforce build of Mesa GLX extension. Drop all other GLX build methods (built-in DRI drivers, etc.).

* MS Windows (non-tested)
* Mac OS X (not provided)
* SGISI / opengl (not provided)
* DRI support (nxagent uses Mesa software emulation only)

 The client-side library libNX_GL.{a,so} is not built when building nx-libs.

 However, nx-X11/lib/GL/** ships several imake include files
 (Imakefile.inc) that are also used in nx-X11/programs/Xserver/GL/**.
 These files have been moved from the nx-X11/lib/GL/ code subtree to the
 nx-X11/programs/Xserver/GL/.

 Furthermore, we don't provide module builds of the GL extension anymore,
 as that feature is neither used in nx-libs.

Fix negotiation in stage 10 error.

 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.

ProcPutImage() calculates a length field from a width, left pad and depth
specified by the client (if the specified format is XYPixmap).

The calculations for the total amount of memory the server needs for the
pixmap can overflow a 32-bit number, causing out-of-bounds memory writes
on 32-bit systems (since the length is stored in a long int variable).
