Parse MAC writes to meta and propagates PDU.
...
This commit extends the Parse MAC block so that it puts the parsed fields in the metadata dictionary of the incoming PDU and also propagates it on a message output. It does not modify the cdr of the PDU. The 'fer' output has been removed, and instead 'Lost frames' and 'Instantanteous FER' are put in the metadata dictionary.

Add beta and csi to decode_mac PDU output.
...
Also changed to using `std::vector<gr_complex>` type because it was becoming more and more inconvenient to use c-style arrays.

Make d_H inherited from base class.
...
All equalizer classes had their own private `d_H` vector, despite all being derived from a common `base` class. Now `d_H` is instead a protected member of `base`, and thus accessible to the derived equalizer classes.

- Added new Viterbi convolutional decoder to the OFDM Decode Mac block replacing the former IT++ version. This new decoder uses
...
SSE2 and improves the performance significantly. The decoder was taken from the gr-dvbt module from GNU Radio.
- Disabled some logging functions in the ofdm_mac and ofdm_decode_signal blocks that were degrading the performance significantly.
