Merge branch 'sync' of git@gnuradio.org:trondeau into master
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.

* 'wip/wxgui' of http://gnuradio.org/git/jblum:
using gr copy in the wxgui connect, added gr copy to grc xml
Added gr.copy(itemsize) block
point label transpareny, horizontal offset, and toggle on/off capability
simplify some params
moved the wxgui connect helper functions into the wrapper class
making use of update ui event
setup special wxgui connect on sinks, needs testing
working special connect for fftsink
work on a special connect function that registers a callback
added bind to visible event function to callback when visibility changes within tabs
Add *.exe to .gitignore
Restore ac_compiler in gr_fortran.m4 even when no Fortran was found
Add $(NO_UNDEFINED) to LDFLAGS in atsc Makefile.am, so shared libraries
will be built
