Add patch: 120_nxagent_libcairo-null-source-drawables.full.patch, solves crashes of GTK applications based on libcairo 1.12.1+.

This reverts commit ab04ba21.

Provide temporary workaround for installation on Debian 64bit with multiarch support (via libnx-x11.postinst and .prerm).

Pass address of fd_set structs on the stack to the FD_ISSET macro/function, instead of the struct itself.

Update patch: 001_add-main-makefile.full+lite.patch, adapt patch from packaging. Test for Makefiles in subfolders before calling them. Fixes build failure during ,,make distclean'' calls.

Fix Xinerama support in Debian package libnx-x11 when NX gets built with patch 600_nx-X11+nxcompext+nxcompshad_unique-libnames.full.patch. Still on the todo list: fix the nx-X11 installation via Makefile.

Update patches: 012_nxcomp..., 013_nxcompext_..., 014_nxcompshad_.... Also make use of $(LIBFULL) in Makefile.in's install and uninstall stanzas. Inspired by Jan Engelhardt's so-version.diff patch. However, the version name change requested in that patch has been rejected for NX (redistributed).

Add patch 600_nx-X11+nxcompext+nxcompshad_unique-libnames.full.patch, use unique library names for nx-X11 based X11 libraries.

Add patch 032_nx-X11_no-x11r6-project-root. We must not overlap with any existing files, therefore, both /usr/X11R6 and /usr are excluded possibilities for ProjectRoot. Use %_libexecdir/somename, since that is still allowed by FHS.

Add patch: 301_nx-X11_use-shared-libs.full.diff, use shared libraries from distribution rather then libs included in source tree.

Rename patches 030_nx-X11_... and 031_nx-X11_..., the tarball roll script currently requires ,,full'' or ,,full+lite'' in the file name.

Merge honor-ac-dirs.patch from Jan Engelhardt (OpenSUSE) with already existing Makefile patches (012_nxcomp..., 013_nxcompext_..., 014_nxcompshad_...).
