If two openfortivpn scripts are started at the same time, a race
condition can occur where the conditional evaluates to true, but the
symlink exists by the time the other script tries to create it

Block restart of the interface if the openfortivpn fails to authenticate.
Without this check, with a bad password, netifd will continually
hit the VPN endpoint with connection attempts

allow use of curl rather than ping to test if a host
is up since a host may not respond to ping, but an
https request is part of the openfortivpn connection,
so this is a more reliable test
also clean up overly verbose logging

By using the netifd for open fortivpn we are able to set up multiple
VPN connections and manage them through the netifd toolset.
This also adds support for binding an openfortivpn client to a given
interface, in which case when that interface comes online, the vpn
will be initiated via a hotplug script.
This is a breaking commit and configurations will need to be migrated
from openfortivpn.config into the /etc/config/networks.
Example configuration via /etc/config/network:
config interface 'ftvpn'
option proto 'openfortivpn'
option server 'example.com'
option username 'USERNAME'
option password 'PASSWORD'
# optional arguments follow
option local_ip '192.0.5.1'
option port '443'
option iface_name 'wan'
option trusted_cert 'CERT_HASH'
option set_dns '0'
option pppd_use_peerdns '0'
option metric '10'
