Fix the often call of event tox_friend_connection_status

Fixes #868

Is made by:
1. Fix enumeration mechanism of Crypto_Connection instances in function send_crypto_packets()
   (this item solves the main problem);
2. Disruption of correlation between parameters of different dimensions
   (the parameters MAX_NUM_SENDPACKET_TRIES and UDP_DIRECT_TIMEOUT have different dimensions).
