[GIT PULL] Refactor signal handling, change log levels, API updates

[Kevin Cernekee]

This patch series updates the command-line client to implement the
signal handling changes discussed previously on the list:

    SIGINT: Disconnect and logoff, run vpnc-script accordingly
    SIGHUP: Disconnect and run vpnc-script (cookie can be re-used)
    SIGTERM: Just die. Disconnect without logoff, no vpnc-script
    SIGUSR2: Reconnect to server immediately as if DPD triggered.

It retires the old SIGUSR1/SIGUSR2 handlers that used to change the
loglevel.  Previously, debug output (-v) was all-or-nothing.  Now -v
enables PRG_DEBUG, which is fairly chatty but should not print per-
packet information or otherwise degrade performance.  In order to see
per-packet messages, a situation that is expected to be very rare,
the user now needs to specify -vv (for PRG_TRACE).

On the API front, this series fixes some out-of-sync definitions for
openconnect_set_pfs(), and adds a new openconnect_set_dpd() function to
accommodate users who require a shorter interval due to connection
flakiness.  The latter feature was requested by a user who is connecting
multiple clients to a mobile 3G<->wifi hotspot as a gateway, and finds
that the hotspot's public (3G) IP address changes frequently without
notice.
