512 cycles. We also now compute the return value based on the
preincremented phase value, thus shortening the dependency chain.
This does put the computed result 1 tick ahead of the previous version
of the code, but none of the code in the tree depends on the absolute
phase. If yours does, sorry. You can work around it by initializing
the phase to conj(gr_expj(phase_incr)) instead of gr_complex(1,0).
Added QA code to ensure I didn't break anything.

accumulator. Thanks to Stefan Bruens and Philip Ballister for working
on this.
According to the fine print in the C and C++ standards, if a signed
integer type overflows, the result is undefined. As of gcc 4.3, gcc
was proving that our code was overflowing, and took advantage of the
"undefined" result to short circuit the evaluation.
Moral of the story: if you're using a fixed point phase accumulator,
or anything else where you're counting on overflow happening, be sure
that your variable is unsigned.

Fix that allows C++ classes derived from gr_hier_block2 to
use the new self() method to get a magic object that can be passed
to connect or disconnect to refer to their own inputs and outputs.
Note that the constructor wrapper of all classes derived from
gr_hier_block2 (and thus gr_top_block too) MUST USE the new
gnuradio::get_initial_sptr function to get the initial shared pointer.
gnuradio::get_initial_sptr works on all block types, and should be
used in all new code. See qa_gr_hier_block2_derived.{h,cc} for an
example.

and decoder corresponding to the R=1/2, K=7 CCSDS standard ("Voyager").
This code is a GNU Radio wrapper around a 1995-era KA9Q portable-C
implementation, and is designed for continuous streaming data, not packets.
The encoder takes MSB packed bytes and outputs channel symbols 0 or 1.
The decoder uses soft-decision Viterbi decoding on a floating point stream of
(possibly noise corrupted) [1.0, 1.0] symbols, and outputs MSB packed
decoded bytes.
Benchmarking on a 2.16 GHz Intel Core 2 Duo shows 4.7 Mbps decoding rate at
100% CPU usage (single core). (There is a newer KA9Q library that implements
SIMD speed ups with correspondingly faster performance.)
The KA9Q library is placed into src/lib/viterbi. It could use some cleanup,
file/function renaming, and refactoring, or even replacement with the newer
libfec code that is available.
