Don't use commit() on each SQL insert, it makes things terrislow.

In progress, temp commit. Have removed pubsub interface in favor of 0MQ sockets -- this gets us free message-passing across network or local host.

Refactored modes_rx to use a more modular radio interface (radio.py) using a pubsub pattern to formalize the old "outputs" interface I was using. Should make it easier to reuse the radio interface.

Added option for pulse matched filtering
...
Pulse matched filtering places a boxcar filter upstream of the
averager and preamble detector. The filter length is equivalent
to the number of samples in one Mode S chip (0.5us). This
technique enhances operation when using sample rates > 4Msps.
When using --pmf, the threshold may need to be reduced a dB or
two from what would have been optimal without --pmf.
* rx_path.py now takes 'use_pmf', defaults to False
* modes_rx has new CLI option '-p' or '--pmf' to turn on PMF
* modes_gui has new checkbox on Setup tab

Refactor flowgraph into hierarchical block
...
This commit creates air_modes.rx_path, which is the common portion
of the flowgraph once the sample source and possible resampler are
created. It takes baseband I/Q and emits Mode-S packets into the
supplied message queue.

Fix preamble/slicer dB numbers. Was using power ratios for voltages (2.0 instead of 1.414 for 3dB, etc.). No real performance change.

Fix suggested by Denis Gapotchenko.

Up the sample rate for RTL dongles to 3.2Msps. Seems to enjoy 3.2Msps just fine, and the Mode S RX works *much* better with the extra bandwidth.
