Attributes GH PR #196: https://github.com/ArcticaProject/nx-libs/pull/196

This patch isn't necessary in Xlib 1.4 and later since the keysymdb has been
made redunant. While we're on 1.3.x, we need it.

Fixes ArcticaProject/nx-libs#205.

randrproto: It was discovered that nx-libs shipped two different version of randr.h and randrproto.h. This commit leaves the newer file versions in the package and let's the build process use those everywhere.

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

hw/nxagent/X11/include/Xrandr_nxagent.h: Reduce injected libXrandr(_nxagent) header file, so that it only contains the XRRScreenChangeNotifyEvent typedef.

This fixes ArcticaProject/nx-libs#204.

However, this fix does not address the root of the problem, it simply avoids
it. We could run into it again... See bugreport for an explanation.

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.)
