This block performs scrambling by XORing the input sequence with
the output of an LFSR. Repeating this operation restores the original
sequence.
(This differs from gr.scrambler_bb(), which convolves the input sequence
with the LFSR output.)
The additive scrambler allows an optional bit count after which the LFSR
is reset to its initial seed. This allows use with, e.g., packetized
fixed length payloads.

Each io pad can have a different io signature.
Uses the iosignaturev for hier implementation.
Backwards compadible with exception:
Pad blocks that used multiple ports must be replaced with multiple pad blocks
as the new pad io blocks only support one port per block.

* 'wip/term' of git@gnuradio.org:jcorgan:
gr-wxgui: cleanup for merge
Consolidated termsink into one class
Basic terminal window that takes raw text on input msgq and appends it
Add placeholder panel for console, use old style window size
Created skeleton wxgui term window component

Works, but needs "--line-buffered" mode for GR buffering between blocks

Merge-fix: Remove debugging print
Merge-fix: Update copyrights
* 'flattopwindow' of http://gnuradio.org/git/jblum:
Added window option to wxgui fft and waterfall sink.
redid cos windows, added flattop and nuttall_cfd

Added rectangular window function to window.py.
Average stays hidden in waterfall, fft, and numbersink wrappers (only avg_alpha shows/hides).
Fixed options in waterfall wrapper to model after fft and numbersink average params.

This merge adds polyphase clock recovery, implements new PAM demodulators
that use it, and also moves GRC examples to gnuradio-examples component.
See merge commit diff for updated files post merge.
* 'sync' of git@gnuradio.org:trondeau: (54 commits)
Reverting dqpsk to be mpsk_receiver based and not change its behavior.
Fixing initialization of timing gains. Alpha should be < 1, and beta should be << 1.
This splits the rate into a fractional an integer value, which allows the loop to adjust the fractional rate while the integer rate keeps the increments moving properly. Allows the max rate deviation to be independent of the integer rate. Scaling of the differential taps also allows alpha and beta to operate independent of the rate when fractional samples per symbol are used. Slightly more tolerant to large signal values, but they still should be close to +/-1.
Fixing compiler warnings.
Adding dqpsk2 block to makefile for installation.
Adding DQPSK version that uses the PFB timing sync block (dqpsk2).
Minor fixes for logging.
Fixing import of UI file.
Temporary working dbpsk2 example until we match everything.
Working DBPSK implementation with new PFB clock recovery block. The feedforward AGC wasn't playing nicely, the frequency aquistion range was increased to swing half the sample rate in either direction, and the number of filter phases to use was increased to 32.
A bit of code cleanup.
Starting to rework QT app to control new PFB clock recovery alg.
Making old dbpsk work again to compare against new version.
Adding new DBPSK block with new PFB clock recovery alg.
Revert "More additions to PAM timing simulation."
More additions to PAM timing simulation.
Using 2-PAM by default.
Cleaning up GRC PAM timing example and adding ability to do M-ary PAM.
Cleaning up constructor.
Moving filter number decision to start work function.
