Add connectionCount and fix Gap state updates

Add a connectionCount member to Gap that keeps track of the total number of
open connections. Also, update the Gap state member when a connection is opened
to set advertising to false. Finally modify the processDisconnection member to
unset the connected state if connectionCount is 0.
