[ANN] added Zbar repository at linuxtv.org

[Mauro Carvalho Chehab <mchehab@s-opensource.com>]

Hi,

Just to let you know, I added today a repository at linuxtv.org with a fork
of the ZBar bar code reader.

The Zbar tool is an interesting V4L2 application, as it reads code bars
from several different codes from a webcam (or a scanned file).

The original page for this project is at http://zbar.sourceforge.net/

Unfortunately, it doesn't have maintenance there, since 2012. This was
its last commit upstream:

	changeset:   362:38e78368283d
	tag:         tip
	user:        spadix@users.sourceforge.net
	date:        Sun Oct 14 23:02:08 2012 -0700
	summary:     Added tag iPhoneSDK-1.3.1 for changeset 5eb3c8786845

At least on Fedora, upstream version doesn't even compile 
without fixing configure.ac to work with modern automake tools.

As Douglas and I are maintaining this package under Fedora, and
I had to write some other patches on Fedora, in order to migrate it
to Qt5, I'm opting to keep a fork of its patched version at
linuxtv.org.

The version there is basically the original development tree,
converted from Mercurial to git. For the few patches at the
Fedora packaging repository, I added a commit, in order to 
preserve credits for the authors of the changes there.

Please notice that I don't have currently any plans to do any
development on it, doing mainly bug fixes as required to keep it 
building and working.

So, if anyone is interested on keeping maintaining it, please
ping me. Feel free to also send patches for it to linux-media ML.

Thanks,
Mauro

	    Update to the very latest version of zbar
    
	    zbar was using a 2010 snapshot of its hg tree.
	    Take a new snapshot to get zbar's improvements.
