agent: Fix long standing regression tracking the connection count.

Browse source 
* agent/gpg-agent.c (get_agent_active_connection_count): New.
(do_start_connection_thread, start_connection_thread_ssh): Bump
ACTIVE_CONNECTIONS up and down.
* agent/command.c (cmd_getinfo): Add subcommand "connections".
--

The variable ACTIVE_CONNECTIONS is used to shutdown gpg-agent in a
friendly way.  Before we switched to nPth a Pth provided count of
threads was used for this.  During the migration to nPth
ACTIVE_CONNECTIONS was introduced and checked but never set.
