Atsc svn update in private branch

FWIW I put all my latest atsc stuff in:

http://gnuradio.org/svn/gnuradio/branches/developers/cswiger/wip

including a recent elimination of another fir filter by making the
input root-raised-cosine filter interpolate by 2 - that in itself
takes one 1.8GHz Opteron cpu load from 84 to 40%. cpll runs at 16Mhz.

One thing you need to do is redo

gnuradio-core/src/lib/filter/interpolator_taps.h

using

gnuradio-core/src/gen_interpolator_taps/gen_interpolator_taps -n
128 -t 12 -B .375 > …/lib/filter/interpolator_taps.h

and to build /that/ you need to ./configure --enable-fortran
