[WIP] Implements reusable sample buffers across all components. This
...
produces a significant reduction in memory usage, especially for tuners
like the airspy and hackrf that produce 10/20 MSPS sample rates. This
is observed to be around 66% reduction in peak memory usage and provides
a more stable memory utilization across time reducing stress on the
garbage collector.
Use of these reusable memory buffers will be pushed further down into
the processing chain modules to ensure we keep new object creation
to the lowest levels possible.

#90 [WIP] merged metadata management for channel state, decoder states and audio metadata into a new metadata class. The new metadata class is maintained for each decoding audio channel, or in the future, a decoding TDMA channel. Audio playback, recording and streaming all use the same metadata object for the channel. The list of channel processing gui panels have been deleted and channel processing status will now reside in a table where each table row is a metadata instance from the processing channel. The channel processing manager is responsible for adding/removing the channel's metadata instance to/from the metadata table. This allows the channel processing table to be the controller for the messages, events and channel spectrum views, keyed to the selected table row metadata.
...
I still have to clean up the gui components and wire in the table selection listeners.

#30 - adds support for Shoutcast V2 (aka Ultravox 2.1) audio streams.
...
Resolves issue with MP3 framing where the remote server was disconnecting us due to bad MP3 sync. The LAME encoder was sending partial 20 byte MP3 frames initiall, then following with a 144 byte array which contained the remainder of the first frame and the header of the next frame. Adjusted the MP3SilenceGenerator to only emit complete MP3 frames.
This should be the final commit for this feature, pending merge back into master branch.

#72 Enhances management of wildcard values for aliases. Calculates a relative weighting for each wildcard alias id and then orders (smallest to largest) the wildcard values so that when attempting to lookup an id value, it first attempts to look for a direct match and then defaults to iterating the list of wildcard values until it finds the most specific or best matching wildcard value.

Closes #72 - updates alias list to maintain a map of alias id to alias and separate lists for wildcard alias id values. Alias lookup logic is changed to first look for in the alias map for a concrete match to the alias identifier. If an alias is not found, then the list of wildcard alias identifier values is iterated looking for a matching wildcard. If the wildcard is found, then the matching alias is returned from the map.
