Bug#526007: [FFmpeg] libxxx-unstripped should also Provide libxxx

Honestly, it is inconvenient to not be able to have libxxx-unstripped
and libxxx-dev installed at the same time. The workaround, however, is
quite obvious: Before building remove libxxx-unstripped and install
libxxx + libxxx-dev instead. After building remove libxxx-dev and
install libxxx-unstripped. However, this will not be needed in future
uploads of ffmpeg anymore. (It will never be possible to have libxxx
and libxxx-unstripped installed at the same time, just to point it out).
Please note that there is no advantage from building packages against
libxxx-unstripped. The packages are API/ABI-compatible with their
libxxx counterparts. So it is perfectly allright to build packages
against libxxx-dev + libxxx and replace libxxx with libxxx-unstripped
afterwards. You will still be able to use all the codecs from the
fully functional library package.
