Bug#799262: [opencv] please provide package python3-opencv

[Kota Kato]

Hi,

I've created a patch to provide python3-opencv package. In my environment,
the patch work well with python 3.5 on the latest stretch.

The package contains the following files:

    $ dpkg -c python3-opencv_3.0.0+dfsg-1~exp2.1_amd64.deb
    drwxr-xr-x root/root         0 2016-03-15 15:06 ./
    drwxr-xr-x root/root         0 2016-03-15 15:06 ./usr/
    drwxr-xr-x root/root         0 2016-03-15 15:06 ./usr/share/
    drwxr-xr-x root/root         0 2016-03-15 15:06 ./usr/share/doc/
    drwxr-xr-x root/root         0 2016-03-15 15:06

    -rw-r--r-- root/root      3471 2015-12-08 13:35

    drwxr-xr-x root/root         0 2016-03-15 15:06 ./usr/share/lintian/
    drwxr-xr-x root/root         0 2016-03-15 15:06
./usr/share/lintian/overrides/
    -rw-r--r-- root/root       105 2016-03-15 12:50
./usr/share/lintian/overrides/python3-opencv
    drwxr-xr-x root/root         0 2016-03-15 15:06 ./usr/lib/
    drwxr-xr-x root/root         0 2016-03-15 15:06 ./usr/lib/python3/
    drwxr-xr-x root/root         0 2016-03-15 15:06
./usr/lib/python3/dist-packages/
    -rw-r--r-- root/root   1439704 2016-03-15 15:06
./usr/lib/python3/dist-packages/cv2.cpython-35m-x86_64-linux-gnu.so

After installing the package, you can use cv2 module as followings:

    $ python3 -V
    Python 3.5.1+
    $ python3 -c 'import cv2; print(cv2.getBuildInformation())'

      Python (for build):            /usr/bin/python2.7

    [...]

It's very happy for me if Debian and Ubuntu officially provide a
python3-opencv package.
