Make the builds faster as we now run them often via Travis.

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.

The supporting scripts weren't really up to date, so remove them
and just require the packager to include FLTK in the source
tarball.

It is needed by x0vncserver.

It is needed to build Xvnc.

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Packages for RHEL 5 and Ubuntu 12.04 are no longer maintained, so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

These are for ancient versions of FLTK and are not needed in the
versions required by us.

Two minor issues:

This script is written in python two which is depreciated, and should be rewritten in python three, but I have so far been successful in not learning python. :-) to simplify debugging I have clarified that it needs a python two interpreter.

This script downloads an old version of mesa (an update may be appropriate),  unfortunately the release candidate previously specified is no longer available, so an update to the next released version was made.

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.

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

Debian patches libtool so that the default value of
link_all_deplibs is set to 'no' rather than 'unknown',
causing transitive dependencies in shared objects to
be lost.

The package is based on the contrib ubuntu-trusty debian package. The
following modifications have been made:

The current tigervnc sources can be used unmodified as the .orig
tarball for the debian package, so get-orig-source.sh is gone.

The ubuntu xorg-server-sources package provides the xorg sources used
to build tigervnc. The two small patches which where in the trusty
quilt series are now applied to the xorg sources after they have been
extracted. There is no quilt series anymore at this point.

Fltk 1.3.3 is available in the xenial repositories and it is used to build
xtigervncviewer. No need to get the fltk sources. patch_fltk.sh is gone.

Fixed some dependencies to reflect changes between trusty and xenial.

Removed configure options not recognized by configure.

The install target is not called a second time for the viewer package,
but the viewer files are moved from the server installation. (Eliminate
file conflicts during binary package installation.)

Note: Some dependencies (including libfltk1.3 and xorg-server-source) are
found in the xenial universe repository only.

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.
