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_...).

Do not install libXinerama directly into /usr/lib/nx. Recommended method is installing to /usr/lib/nx/Xinerama, so that you can enable/disable usage of the Xinerama extension.

Revert "Add patch: 111_nxcomp_byerace.full+lite.patch. Work around race condition in qtnx and libnxcl."

This reverts commit 4eae840b. It does not fix qtnx failures that occur with
this version of nxagent.

Use ,,$(MAKE) -C'' in main Makefile for calling Makefiles in subdirectories, make build stanza work for nx-libs-full and nx-libs-lite.
