gnuradio-core: removed gr.dd_mpsk_sync_cc block as obsolete
Add new block gr.additive_scrambler_bb()
This block performs scrambling by XORing the input sequence withthe output of an LFSR. Repeating this operation restores the originalsequence.
(This differs from gr.scrambler_bb(), which convolves the input sequence...
Adding a band-edge based frequency lock loop.
Added gr.copy(itemsize) block
set_enabled(bool) will either copy from input to output (True)or drop the input on the floor (False).
Implements ticket:401 and ticket:402.
Adds several API functions to determine build constants at runtime, anda convenience command line program to display them:
From C++:
const std::string gr_prefix();const std::string gr_sysconfdir();const std::string gr_prefsdir();...
new fm detector added based on FIR derivative detector. Stereo sep better than pll based one and more efficient. Tweaking probably needed, usrp_wfm_rcv_fmdet added to demo

merging branch -r9485:9498 to fix some warnings. This merge removes some of the old OFDM mappers that were specific to BPSK, QPSK, and QAM constellations. These were never really used and should not be.

Merging ofdm2 branch -r7047:7321 into trunk. This updates the OFDM code to hier_block2 in blks2impl and removed from blksimpl. The new codeimplements a decision feedback sync loop to lock the phase/freq, removes two unnecessary premables and performs frame sync and equalization off...
merged -r5966:6112 on trondeau/ofdm_mod. Allows for generic constellations (supports bpsk, qpsk, 8psk, qam16, qam64, and qam256 currently), fixes some bugs in the correlation and altered default parameters for over-the-air operation. This merge fixes ticket:156 and ticket:157....
Updated license from GPL version 2 or later to GPL version 3 or later.
