drbob 74961774cc * Added new interface functions for start / stop DHT and to get stats.
* Implemented start/stop interface in udpbitdht and bemanager
 * added Restart of DHT if it fails to get going.
 * added start / stop functionality to bdnode and bdstore
 * added cleanup code to rest of bitdht classes.
 * reworked NetworkSize calc functions.
 * added thread debugging (prints at start / stop / join).
 * TESTS: added utest.h header file for automated unit testing (from libretroshare)
 * TESTS: bdmetric_test started conversion to automated tests
 * TESTS: udpbitdht_nettest. Added dht start / stop and network reset (thread join) functionality.
 * TESTS: fresh bdboot.txt
