The RPM macro for the linker flags does not exist on EPEL. Thus, hardcode __global_ldflags macro for EPEL builds.

Improve patch: 601_nx-X11_build-option-changes-to-not-use-bundled-libraries.full.patch. Improvements taken from the current Fedora package. Thanks to Orion Paplowski!!! Also adapt roll-tarball.sh do dropping more bundled libraries.

Add patch: 302_nx-X11_do-not-build-bundled-libs.full.patch. Rename patch: 302_nxagent_configurable-keystrokes.full.patch.

* Add patch: 302_nx-X11_do-not-build-bundled-libs.full.patch. Taken from Fedora.
  Do not build bundled libraries, rather use system libraries instead.
* Rename patch: 302_nxagent_configurable-keystrokes.full.patch to
  320_nxagent_configurable-keystrokes.full.patch.

prep source tree after unpacking tarball, bring files from debian/ folder in place before building the RPM package

Ship nx-libs.spec (RPM package definitions) in upstream project. (Thanks to the Fedora package maintainers). File differs from the Fedora file already.

Add patch 605_nxcomp_Types.h-dont-use-STL-internals-on-libc++.full.patch. Fix FTBFS of nx-libs-lite on Mac OS X Mavericks. (Fixes: #337).

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.
