Legacy Xext proto versions are automatically detected by the main
Makefile.

Partly reverts ec30a857, but in a
forward-compatible manner.

Legacy libXfont1 versions are automatically detected by the main
Makefile.

 Fixes ArcticaProject/nx-libs#80

 Fixes ArcticaProject/nx-libs#296.

 Inspired by the following X.org commit. Other than X.org, we will continue
 support for building nx-libs against libXfont1 for a while.

    dix: Switch to the libXfont2 API (v2)

    This new libXfont API eliminates exposing internal X server symbols to
    the font library, replacing those with a struct full of the entire API
    needed to use that library.

    v2: Use libXfont2 instead of libXfont_2

Xserver/os/oscolor.c: Follow X.org in dropping the rgb.txt file entirely. Content of that file is now hard-coded.

 Adopting an exact copy of os/oscolor.c from X.org leads to this compiler warning:

 ```
 oscolor.c:844:1: warning: string length ‘7614’ is greater than the length ‘4095’ ISO C99 compilers are required to support [-Woverlength-strings]
 };
 ^
 ```

 This will be address later in coordination with X.org.

 Note: there is a tiny change in oscolor.c as we ship it. The original X.org file includes <X11/keysym.h> which seems
 unneeded. We drop that one line from oscolor.c.

 Fixes ArcticaProject/nx-libs#259.

just as Xorg upstream did

We do not build loadable modules, so we do not need them anywhere.

Also remove the extra files requires for module builds.

nx-X11: Enable -Wpedantic as default CFLAG. This is to detect redefined typedefs when building nxagent.

Per-file copyright notices: Update copyright information in file headers that NoMachine placed there own copyright statement in.

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

library clean-up: Don't build libNX_Xdamage anymore. Use system's libXdamage shared library. (Fixes ArcticaProject/nx-libs#6, X2GoBTS#826).

library clean-up: Don't build and link libXfont.a anymore. Use system's libXfont shared library and link dynamically.

 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).

Do not build bundled libraries (601_nx-X11_build-option-changes-to-not-use-bundled-libraries.full.patch).

  This commit has been submitted by Orion in two
  portions. One was submitted to X2Go BTS and created

  The other portion has been taken from the Fedora

  patch on Fri, 06 Dec 2013.

  Many distributions have a policy to reduce code duplications.
  One means to avoid such duplications is to use shared libraries
  instead of using libs that are ofter shipped for convenience.

  Debian (Section 10.7.4 of Debian policy):

  This patch adds Xinerama awareness to NX agent windows.

  The advantage of Xinerama awareness is that an NX session window
  will only maximize to the dimensions of the active physical
  display.

This reverts commit e77bf36d.
