merging branch trondeau/ofdm r7971:8143. Fixing subcarriers and other issues to improve OFDM system operation. Not much more we can do with this than add channel coding and cleaning up.

merged -r7836:7846 from trondeau/ofdmtiming to trunk. This fixes the big issues in transmitting OFDM over the air with 1 preamble symbol. Still some smaller issues left.

Merging trondeau/ofdmfix into branch at -r7582:7586. This allows for over-the-air OFDM. Works with all modulations and tested both send and receive on different computers/USRPs. Misses a few packets, so it's not perfect.

Merging ofdm2 branch -r7047:7321 into trunk. This updates the OFDM code to hier_block2 in blks2impl and removed from blksimpl. The new code
implements 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....
