- Fix race-condition between data TX watchdog timer and handshakes retries timer
- (at the same time) Fix and unify handshake attempts counter usage: now 0 means no HI in progress. Can use that timer to check if and HIs already sent.
- Do not flood new handhake initiations, if HI is already scheduled by somebody else.

0 means no HandshakeInitiation (HI) is in progress. Positive number - how many HIs have been already send. This patch also fixes race condition between HI retries and data sent watchdog timer(timersDataSent vs expiredRetransmitHandshake) Signed-off-by: Antanas Gadeikis <antanas.gadeikis@nordsec.com>

Initially those raceconditions were observed on Windows. |

This is deliberate I believe. If you don't retry once already in progress, then a single lost packet would prevent a connection from being established. |
