debian/*.dirs: Don't create directories in the Debian package. All handled well by the upstream Makefile.

 ... detected by Debian's lintian tool.

debian/control: Drop various not-used-anymore libNX_* related packages. Add B:/R: to libnx-x11-{6,dev,6-dbg) to uninstall those package when upgrading to nx-libs 3.6.x.

roll-tarball.sh: Don't ship doc/X11-symbols/ in the lite (proxy-only) tarball derived from the nx-libs code tree.

debian/rules: Don't attempt at removing $(CURDIR)/.preserve/. Not needed anymore since we removed the CODE-REDUCTION_* hacks from debian/rules.

 Note:

  - The "normal" way to inject CFLAGS (and CPPFLAGS) into nx-X11 builds is copying those
    options over into the variable CDEBUGFLAGS.
  - LDFLAGS have to be handed to nx-X11 via LOCAL_LDFLAGS.

 This change also includes a slight change in the nx-X11 build order.

 Old build order:

  Main Makefile:

      - [...]
      - libNX_X11
        + implicitly building nxcomp
        + implicitly building nxcompext
      - [...]
      - nxagent
        + implicitly building nxcompshad
      - [...]

 New build ordner:

  Main Makefile:

      - [...]
      - nxcomp
      - setup nx-X11 build env
        + cd nx-X11 && make BuildEnv
      - nx-X11/lib/*
      - nxcompext

This required for successful linking of libXrender against libNX_X11.

Port from libXfixes commit b031e3b60fa1af9e49449f23d4a84395868be3ab We
need this here to enable linking of current libXrender against
libNX_X11 instead of the system's libX11

The original implementation of this function (libX11 commit
9f5d83706543696fc944c1835a403938c06f2cc5) uses xcb stuff which we do
not have in libNX_X11. So we take a workaround from another lib. This
workaround had been added temporarily to a couple of X extension libs,
see
e.g. https://lists.x.org/archives/xorg-devel/2013-July/036763.html.

To enable linking of a current libXrender libNX_X11 needs that symbol.

This is a (manual) backport of the following upstream libX11 commit
available at
https://cgit.freedesktop.org/xorg/lib/libX11/commit/src/XlibInt.c?id=4a060f993bf676cf21ad9784e010f54134da7b40:

 The x2goagent package is being replaced by an x2goserver bin:package
 named x2goserver-x2goagent.

 This x2goserver-x2goagent bin:package will be maintained in the X2Go
 Project's namespace and basically wraps around nxagent.

 Furthermore, declare Arctica Project as upstream source for nx-libs.

fix wrong bin:package for Xext proto headers: Move dpmsstr.h and securstr.h from Xext devel package into proto header package.

 We have to make sure that all X.org libraries we link against
 use symbols provided by libNX_X11.
