Makefile: Adapt install target to the new situation where we fake X11 headers in .build-export. This fixes FTBFS during file installation into .deb and .rpm packages.

nx-libs.spec: Add BuildRequires: imake

Fixes ArcticaProject/nx-libs#202.

Attributes GH PR #201: https://github.com/ArcticaProject/nx-libs/pull/201

After commit cbf3ef0f219a7d5c94a7f5d5b46c9a0e26cc6588 this no longer
necessary.

This reverts commit 9a4bb50a.

System headers including other headers via <X11/..> now use the
nx-X11 variant (if existing).

With this patch in place we should think about dropping the
<nx-X11/..> namespace now for includes.

Fixes ArcticaProject/nx-libs#200.

Attributes GH PR #199: https://github.com/ArcticaProject/nx-libs/pull/199

xserver upstream has included the required files. So do we.

Upstream does not use xkbfile but has own copies of the required
files. It was not used elsewhere.

nxcomp/Loop.cpp: We have PrintVersionInfo(), why not use it? Use endl instead of \n for EOLs when streaming application's preamble to stderr.

nxcomp/Loop.cpp: We have GetCopyrightInfo() in Misc.cpp, so why not use it? Also: point to ArcticaProject/nx-libs namespace on Github for further information.

hw/nxagent/Init.c: Fix copy+paste flaw when re-arranging copyright information as display by nxagent.

nxcomp/Loop.cpp: Refer to Github namespace of Arctica Project as location to search for software updates.

 Fixes ArcticaProject/190

 Fixes X2GoBTS#952

nxagent.1 man page: Some layout fixes for string options with well-defined expected selections of values.

hw/nxagent/Display.c: Fix comment where the meaning of the "bypass" reconnectchecks parameter value is explained.

Attributes GH PR #183: https://github.com/ArcticaProject/nx-libs/pull/183

Together with PR #143 this fixes ArcticaProject/nx-libs#132.

t merges an updated upstream into a topic branch.

nx-X11/programs/Xserver/hw/nxagent/Display.c: add FIXME comment to nxagentCheckForColormapsCompatibility().

Maybe needs special strictness handling as well.

Maybe needs special strictness handling as well.

nx-X11/programs/Xserver/hw/nxagent/Display.c: split up nxagentCheckForPixmapFormatsCompatibility() and nxagentInitPixmapFormats().

Don't implicitly call the checking function in the init function (and throw
away the checking functions result...)

Instead, explicitly use the checking function after the init function in other
parts of the code and throw away the checking functions return value
selectively or actually use it while reconnecting.

This is totally different behavior compared to the original one. Hopefully it
doesn't cause any problems (i.e., hopefully there was no good reason for never
using the checking functions return value, but an oversight.)

nx-X11/programs/Xserver/hw/nxagent/Display.c: use new ReconnectTolerance nxagentOption value in nxagentCheckForPixmapFormatsCompatibility() and modify behavior based on this value.

Recognized values:
  - Strict means that the number of internal and
    external pixmap formats must match exactly and
    every internal pixmap format must be available
    in the external pixmap format array.
  - Safe means that the number of pixmap formats might
    diverge, but all internal pixmap formats must
    also be included in the external pixmap formats
    array. This is recommended, because it allows
    clients with more pixmap formats to still connect,
    but not lose functionality.
  - Risky means that the internal pixmap formats array
    is allowed to be smaller than the external pixmap
    formats array, but at least one pixmap format must
    be included in both. This is potentially unsafe.
  - Bypass or higher means that all of these checks are
    essentially deactivated. This is a very bad idea.

Note that the default ReconnectTolerance value is still Strict.

Also, the return value of this function is currently not used or passed through
to other functions at all. An upcoming commit will change this behavior and
actually enable the checks.

nx-X11/programs/Xserver/hw/nxagent/Display.c: use new ReconnectTolerance nxagentOption value in nxagentCheckForDepthsCompatibility() and modify behavior based on this value.

Recognized values:
  - Strict means that the number of old and new depths must
    match exactly and every old depth value must be
    available in the new depth array.
  - Safe means that the number of depths might diverge,
    but all former depth must also be included in the
    new depth array. This is recommended, because
    it allows clients with more depths to still
    connect, but not lose functionality.
  - Risky means that the new depths array is allowed to be
    smaller than the old depths array, but at least
    one depth value must be included in both.
    This is potentially unsafe.
  - Bypass or higher means that all of these checks are
    essentially deactivated. This is a very bad idea.

Note that the default ReconnectTolerance value is still Strict.

nx-X11/programs/Xserver/hw/nxagent/Display.c: use new ReconnectTolerance nxagentOption in nxagentCheckForDefaultDepthCompatibility() and modify behavior based on this value.

Recognized values:
  - Strict means that the old and new default depth values
    must match exactly.
  - Safe or Risky means that the default depth values
    might differ, but the new default depth value must be at
    least as high as the former default depth value. This is
    recommended, because it allows clients with a
    higher default depth value to still connect, but
    not lose functionality.
  - Bypass or higher means that all of these checks are
    essentially deactivated. This is probably a very
    bad idea.

Note that the default ReconnectTolerance value is still Strict.

{nx-X11/programs/Xserver/hw/nxagent/{Args.c,Options.{c,h}},nxcomp/{Loop,Misc}.cpp}: add tolerancechecks parameter as an nx/nx option and ReconnectTolerance as an nxagentOption.
