Or rpmbuild gets grumpy.

Add missing build requirements: libpng-devel, zlib-devel

Remove obsolete build requirements: libXfont-devel

Fix unexpected rpm macro expansion `%{VERSION}` which is supposed
to be passed through as literal to `rpm -q --qf`. This hasn't
caused problems before, but it was found to cause problems when
built from EL 8 when it expanded to "1.10.1".

Update RPM package build process to automatically detect and apply
the correct X.org patch.

This makes our builds directly compatible with most distributions
without packagers/users having to specify extra flags.

Running as a service on a SELinux system requires rules so we can
transition to our own context. We also need the proper permissions
to start new user sessions.

This sets up a more correct session as there are key tasks that
need to be performed by PAM. E.g. systemd will allocate cgroups
and start base services.

In order to easily handle this as a system service the mapping of
displays is now done via a configuration file.

It is the most common init system these days so it should not be
hidden in the contrib/ directory.

This also removes all old SysV files from the contrib packages.

Install some example files to make things more easily discoverable.

These are EOL (or soon to be) and we want to start relying on things
present in current distributions.

Remove the unused Java self sign variable, and make sure we don't
hard code a version as it needs to be adjusted before a build.

libXft is needed to build FLTK for the RHEL 6 RPM.

It is needed by x0vncserver.

They include a new enough version, so stop doing our own build.

Packages for RHEL 5 and Ubuntu 12.04 are no longer maintained, so
remove those files.

Our main web site now supports https, so update all references.

Applets don't work anymore so remove everything that has to do
with serving them.

See issue #534

OpenJDK 7u111 on el6 now throws an exception if the TSA URL scheme
is https.

Patch taken directly from f22 nettle package

NASM 2.01 can be rebuilt from el6 spec file

Additional change need for dynamic build of libX11

Building libX11 statically causes problems with libpthread, however
the version of libX11 that ships with el5 is too old to build libXext.
So we have to build a dynamic version of libX11 and link against that
while building.  The resulting binary will actually be linked against
the system libX11, which should be ABI compatible as far as Xvnc is
concerned.

These files are not Red Hat or Ubuntu specific, so install them
on all Unix systems where the viewer is installed.

Split the static library pre-reqs into a static-devel package
so that they don't need to be rebuilt everytime tigervnc's
sources change.

Several of the pre-requisites have outstanding CVEs.

Build with rpath link so that Xvnc finds our libGL even if
it's not installed in "/".  Also applied dridir and xkbcompdir
patches so that the correct DRI driver gets loaded.

Added patches for the following upstream CVEs: 2013-7439,
2015-0255, 2015-1802, 2015-1803, 2015-1804.  Also updated the
versions of gnutls, libtasn1, and libjpeg-turbo used to build
static libraries to their latest respective upstream versions.

Bump spec version to match changelog.
