EOSIO 2 Fixes and Other Changes

Security bug fixes

1. Consolidated Security Fixes for 2.0.x

Stability bug fixes

1. Net plugin sync * Fix issue with getting in infinite loop while processing handshake * Guard against overflow of handshake generation count * Fix problem with self connection logic * Better handling of sync/head-catchup transition.

2. Net plugin handshake * Send handshake when done syncing for case where node has moved while syncing * When unable to fetch a block during sync send handshake. This was sending a go away message before which was too aggressive. * Clear out queue buffer always on async write callback otherwise non-empty queue prevents send on re-connect. * Fix calculation of peer lib on lib catchup

3. net_plugin lib sync * Fix for corner case of request next chuck during sync determining already caught up to lib.

4. net_plugin boost asio error handling * Use error codes & catch exceptions from boost asio to avoid terminate on errors.

5. net_plugin thread protection peer logging variables * Protect access to logging variables used by peer_?log macros

6. Fix race in fc::message_buffer and move message_buffer_tests to fc.

7. reset the new handler
