None of the old releases were uploaded to the official Debian repo,
so list them as UNRELEASED.

3.4.0-1 was the first release uploaded to Debian (unstable), but it was
rejected by the ftpmasters so mark it too as UNRELEASED.

Followup on PR#57 Create readme source

Add --backup-flash and --restore-flash commands

More debs

Add a debian packaging workflow

Just what I found locally in my master branch.

This doesn't work on debian.

Fix copyright - my previous PR should have been against master

debian/copyright: avoiding extra "Copyright:"s

Changed my opinion on the debian/* entry since the authors are not a subset.

fix d/copyright

Flesh out copyright, based on feedback from the Debian FTP Masters.

Create d/README.source

d/rules origtarxz: Introduce common root for source tree

And an outreach to the Debian community.

no need to override dh_clean

Preparation for upload to Debian.

This was used to remove non-source files that were used by the Windows
build of mesaflash.  These files were removed from git, so there's no
need to handle them specially when running `debian/rules clean`.
