This allows us to simplify things by getting rid of some old
compatibility code. People should really be using current versions
of GnuTLS anyway to stay secure.

We're not testing or maintaining anything older than that.

This means that we can remove a lot of conditionals and fallback code.

It just adds noise and you can't really tell which timer it is
anyway without more logging in other places.

The internal Xorg headers are very incompatible with C++ and we've had
to resort to all kinds of hacks in order to include them in our C++
code. This approach isn't really viable long term so restructure things
so that we have a glue layer written in C that bridges the Xorg core
with the RFB classes.

Remove support for openSUSE 11.4

Oops, didn't realize these changes wre on the branch from an
old pull request.

Project Evergreen stopped supporting 11.4 in October and it's not feasible to
back-port the patches for the Xorg 2014-12-09 CVEs, so as a result we can no
longer provide pre-built packages for this distribution.  The genric binaries
can be used instead.

RHEL/CentOS 6.6 bumped the version of xorg to 6u6, which broke
software GLX because Xvnc wasn't properly linked against libglapi.

Fixes for rpm-based distro builds

Some minor adjustments to sync up the el6 spec file with fedora.

RPM build failed when the self-signed cert was used because the macro did not
expand correctly.

There is no need for these to be global symbols as they are only
used in that file.

They were not very end user friendly so redo more or less all of them.

This variant keeps more context for the translators by having related
strings clumped together.

Both SSecurityVeNCrypt and SSecurityStack are wrappers around other
security objects, so they need to delegate the properties of those
sub-objects properly.

A read-only client should not be allowed to kick out other clients.
It will be forced into shared mode, or refused the connection, depending
on the neverShared parameter.

So clients with limited access rights can not affect it.

More RPM spec file cleanup

* Removed obsolete patches from openSUSE packages

SPEC file cleanup

* Removed the hard coded snap tag, if needed it should be passed in
  via "rpmbuild --define 'snap ...'".
* Changed the hard coded version to "@VERSION@" to make it clear
  that the copy of the spec file in the repository needs to be
  updated manually.

Remove libvnc server module from statically built versions

* The static libvnc server module can't be loaded anyway so just
  remove it from the el5 and portable binaries.

More Java viewer clipboard handler fixes

* Override TransferHandler.exportToClipboard method to ensure that
  serverCutText updates get sent to the system clipboard.  This
  wasn't always happening when relying on the super class' paste()
  method alone.
* Removed some unnecessary setText() statements and one check for
  whether sending client cut text is enabled.

The 1.4 branch is now live, so change the version number of the
development builds.

They use char* rather than void*, requiring a cast here.

It's much more difficult to test for this on Windows since the
headers have version guards. Just play it safe and assume it is
missing. We can remove this check when we raise the base requirements
to Vista (or newer).

We had already fixed the others, but this one was overlooked.
