nx-X11/programs/Xserver/hw/nxagent/Handlers.h: fix stack smashing related to different data type sizes between Xserver and Xlib.

While on the X server side we were expecting a 32bit value, the Xlib side in
nxcompext wrote a 64bit integer to the 32bit location, hence overwriting
"random" data on the stack (most notably the return adress.)

We can work around this by using the Xlib-based Window data type on the
server-side as well, but this problem is likely a more general one.

Calling functions from libcompext in nxagent sounds like a bad idea. Other code
locations might well be affected by issues alike to that as well.

In order to silence compiler warnings, use a "macro hack" for overriding the
"Window" type in NXlib.h.

nx-X11/programs/Xserver: Include nxcomp{,ext,shad} headers like one would do with system-wide shared libraries.

nxcomp/Makefile.in: Only install MD5.h, NX.h, NXalert.h, NXpack.h, NXproto.h and NXvars.h as publicly available header files.

 * Also adapt debian/libxcomp-dev.install.in accordingly.
 * Also adapt nx-libs.spec accordingly.

 * Also adapt debian/libxcompshad-dev.install.in accordingly.
 * Also adapt nx-libs.spec accordingly.

nx-X11/programs/Xserver/Imakefile: Don't overlink nxagent. Linking against libXrandr and libXtst is not necessary for nxagent.

Fixes ArcticaProject/nx-libs#110.

nx-X11/config/cf/lnxLib.tmpl requires post-library removal cleanup: Drop references to dropped X11 extension client libraries.
