* implement support for LC_GROUP_UPDT (this includes the RPC between the CC and VC's to announce active TG lists); completely and entirely refactor how packet handling threads are done, use a new method introduced for this, thread pool resources. this will ultimately be more resource consuming depending on configuration as the worker threads for packet processing stay alive along side the main process. this should be more performant (because we're not constantly creating and destroying threads) and will prevent error conditions that can cause an extreme number of threads to spawn;
* reduce influx and V.24 thread pool sizes; add calculation of how long between when a packet was Rx to when it began proper processing;
* don't use void* for the task routines;
* rename ThreadPoolCallback to ThreadPoolTask; add some checking around task validness; correct a valgrind issue with RawFrameQueue() write not deleting the buffer before return;

* fix issue with naive approach to handling PL_ACT_PEER_LIST data fragementation;
* disable accidental debug code;
* instead of asserting, throw a log error message and discard network packet;
* lock the talkgroup tables when a find is in progress (this will prevent some weird concurrency behaviors because talkgroup rules does not use the concurrent vector);
* if filter headers or terminators is enabled, and the target peer is in the exclusion list, do not send headers or terminators;
* exclusion check should happen before the rewrite check;
* implement dvmpatch, this is a new utility that allows simple TG to TG patching;
* ensure FNE downstream peers that report as peer link have implicit always rules applied to them (i.e. they will *always* receive *all* traffic); correct order of operations when deleting a peer entry (delete connection *AFTER* removing from peers table);
* document concern over possible null ref concurrency issue;
* don't be overly aggressive with FNE process niceness, nice of -10 is more then sufficient;

* remove extraneous check, this is really not necessary since FrameQueue does the size validation;
* clarify the description of the "embedded FNE";
* merge changes from https://github.com/CVSoft/dvmhost to place spec specific limits on channel spacing;
* refactor how network traffic is handled, we don't handle protocol specific stuff within BaseNetwork anymore and offload that to the specific protocol controller instead; implement support to receive peer traffic and repeat (still need to do master to peer);
* convert fatal error about Rx frequency being below base frequency to a warning instead;
* fix incorrect redefine of slotNo;
* correct ret flag for readDMR, readP25 and readNXDN not being set to true by default (stupid me); correct FNE-mode payload offsets for diagnostic packets;

* part 1 of a fix for #30, the change here would be to allow the VCs to know about the CC to be able to report back to it to release or other wise update grants;
* part 2 of the fix for #30, this implements the actual logic for a VC to notify the CC of a grant status change (touch, release) [NOTE: this could have undesirable consequences and this commit is experimental!];
* update README.md;
* fix terrible copy and paste job resulting in a poor logic check (SMH); print to log the control channel address and port at startup; use the appropriate REST API for touch (whoops);
