Add patch 604_nx-X11_recent-freetype-API.full.patch. Fix FTBFS against recent (>= 2.5.0) libfreetype6 API.

Add patch: 603_nx-X11_compilation_warnings.full.patch. Fix 3 evident bugs: one implicit function declaration issue and two array index out of bounds issues. (Fixes: #314).

Add patch: 602_nx-X11_initgroups.full.patch. Fix calling setuid and setgid without setgroups or initgroups. There is a high probability this means it didn't relinquish all groups, and this would be a potential security issue to be fixed. Seek POS36-C on the web for details about the problem. (Fixes: #293).

Change build options so that bundled libraries are not used anymore at build time. Remove bundled libraries from rolled tarballs, as well. (Fixes: #116, #238).

Use a keystrokes.cfg that reflects the normally hard-coded defaults of a vanilla nxagent. (Fixes: #223).

  + Only install keystrokes.cfg when in full mode.
  + Only install nxproxy wrapper when in lite mode.

Provide a default keystrokes.cfg in /etc/nx (for nxagent) and /etc/x2go (for x2goagent). (Fixes: #199).

Fix faulty symlink path. Make sure that x2goagent symlink does not point to absolute path somewhere within the build environment.

This reverts commit e77bf36d.

Add Jan's reasoning for using string_rep() instead of bash based string substitutions as comment to /debian/Makefile.replaces.sh.

Main Makefile: Use absolute symlink when linking from $(X2GOLIBDIR) into $(NXLIBDIR) (i.e. linking x2goagent -> nxagent). (Fixes: #143).

Work-in patch from Jan Engehardt for working around different improper bash implementations of string-in-string replacing. (Fixes: #145).

Avoid building of libxcomp1 (which actually is identical to libxcomp3, just with a wrong name). (Fixes: #104).
