[CinCV TNG] Unbundled build scripts now available with only limited testing

Because some people object to bundled software, like cinelerra-gg, 3
unbundled build scripts were checked into the GIT repository yesterday.
These 3 were each tested at least once so all you have to do is just check
it out and run it,  There is arch.bld, deb.bld, and rpm.bld.  Below is the
current documentation that will go into Features5.pdf.
*Unbundled Builds*

There are some generic build scripts included in the Cinelerra 5 GIT
repository for users who want to do unbundled builds with ffmpeg already
available on their system. This has been tested on Arch, Ubuntu 18 and Leap
15 (RPM) at the time this was documented.

The reason that Cin 5 traditionally uses thirdparty builds (bundled builds)
is because there are a lot of different distros with varying levels of
ffmpeg and other needed thirdparty libraries. However, some users prefer
using their current system baseline without another/different copy of
ffmpeg. With different levels of the user’s libraries, uncertainty,
potential instability, and unknown issues may come up while running Cin 5
and this will make it, for all practical purposes, impossible to diagnose
and debug problems/crashes. There may be no help in these cases. You are
encouraged to report any errors which potentially originate from cin5, but
if the data indicates alternate library sources, please report the problems
to the appropriate maintainers.

With the unbundled builds, some features may not be available and no
attempt to comment them out has been made. So if you use a pulldown, or
pick a render option, or choose something that is not available, it just
will not work.. For example, unless special options were set up by you, the
LV2 audio plugins will not be available. Nor will the codec libzmpeg, the
file codec ac3, or DVD creation. The old school file classes will all work,
but some of the formats that come with ffmpeg may not because of the way
that ffmpeg was installed on your O/S. That is because the Cinelerra ffmpeg
is a known static build and is usually the latest stable/released version.
In the current case of Leap 15, libx264 and libx265 are not built in and
this can be debilitating; You can always run “ffmpeg -formats” and “ffmpeg
-codecs” to see what is available on your system.
