Part 1 of Debian/Ubuntu binary packaging update for 3.2 release.
Creates all C++ API binary and dev packages, with their associated
runtime dependencies.

* Runtime shared-library packages:

-libgruel
-libgnuradio-omnithread
-libpmt
-libmblock
-libgnuradio-core
-libgnuradio-alsa
-libgnuradio-qtgui
-libusrp
-libusrp2
-libgnuradio-usrp
-libgnuradio-usrp2

* C++ development headers and pkg-config files for the above:

-libgruel-dev
-libgnuradio-omnithread-dev
-libpmt-dev
-libmblock-dev
-libgnuradio-core-dev
-libgnuradio-alsa-dev
-libgnuradio-qtgui-dev
-libusrp-dev
-libusrp2-dev

NOTE: For consistency, libqtgui.so has been renamed to libgnuradio-qtgui.so,
and libgr-usrp2.so has been renamed to libgnuradio-usrp2.so.

A 'gnuradio-dev' virtual package will be created that will depend upon the
above -dev packages, so installing that one package will pull in all that is needed
to do pure C++ development in GNU Radio.
