the symlink libXcompext.so.3 was not installed correctly.

Spotted by Orion Poplawski orion@cora.nwra.com

it is automatically generated and clean during the package build

instead, clean stale configure files programatically from the clean rule
in debian/rules.

Instead, place the makefile into debian/Makefile.nx-libs. This makes the
makefile easier to edit.

This change makes debian/rules a bit easier to read

If stricter dependencies are really required, they should absolutely be
specified in the shlibs file instead.

It seems that there is a race condition in the implementation of the
nx-x11 makefiles somewhere. On machines with many cores and high levels
of parallel workers (for me, 32 cores and -j20), nxcompext gets built
before libNX_X11 is ready:

+ ln -s ../../lib/X11/libNX_X11.so .
/usr/bin/ld: cannot find -lNX_X11
collect2: error: ld returned 1 exit status
make[9]: *** [libXcompext.so.3.5.0] Fehler 1
make[9]: Leaving directory `/srv/scratch/tartler/nx-libs/nxcompext'

Until those makefiles get fixed, better disable parallel operation

The Debian xterm package depends on xbitmaps.  This change allows
compiling on a host that has xterm installed.

According to lintian, this is a severe error. Demote to recommends to
ensure that it still gets installed by default.

this package contains debugging information for all code that is built
from this source package.

Follow-up commit for 302_nxagent_configurable-keystrokes.full.patch, fixes FTBFS problem with the first version of that patch.

patch application, fixing up follow-up patches, cleaning up patch-system).

Add patch: 210_nxagent_configurable-keystrokes.full.patch, replaces the hardcoded nxagent keybindings by a configurable table of keybindings.

Fix wrapper scripts: make sure all NX executables can be launched if NX gets installed via the tarball installation method.

Modify patch: 001_add-main-makefile.full+lite.patch. Install nx* and x2goagent wrapper scripts during make install.

Add patch: 025_nxproxy_no-configure-file.full+lite.patch. Remove unneeded build file from NoMachine's nxproxy sources.

Add patches: 024_fix-make-clean.full.patch, 024_fix-make-clean.full+lite.patch. Fix clean-up of build tree after make build has run.

Drop patch 032, fix other patches so that installation via make install installs NX components to /usr/local/lib/nx and /usr/local/include/nx.

Modify patch: 032_no-x11r6.full.patch. Install nx-X11 to /usr/local/lib/nx. Add patch: 032_no-x11r6.debian.patch. Use /usr/lib/nx for nx-X11 on Debian.
