Before this patch, if we specify a plugin specific option through
`pppd_options` in /etc/config/network, e.g. `rp_pppoe_verbose 1`, pppd
would quit with the following error in log.
Wed Oct 9 09:42:58 2013 daemon.notice netifd: GORG (1689): /usr/sbin/pppd: unrecognized option 'rp_pppoe_verbose'
Wed Oct 9 09:42:58 2013 daemon.err pppd[1689]: unrecognized option 'rp_pppoe_verbose'
Wed Oct 9 09:42:58 2013 daemon.notice netifd: GORG (1689): pppd version 2.4.5
Wed Oct 9 09:42:58 2013 daemon.notice netifd: GORG (1689): Usage: /usr/sbin/pppd [ options ], where options are:
This is due to the requirement that function add_option() should be
called by the plugin_init() function first before pppd can parse those
options.

proto_pptp_setup is responsible for loading the required modules to establish
a pptp connection to a foreign peer. The function checks whether all required
modules are already loaded, before actually loading them.
It seems that the filter being used to accomplish this, is not restrictive
enough in some cases. For instance when pptp nat helper modules are present on
a system, and already loaded before a pptp connection is enabled. Then the
search filter (possibly) returns the following for module=pptp, where actually
no matches are expected, resulting in the pptp.ko module not being loaded,
thereby failing to establish the pptp connection.

The search filter can be made more accurate/restrictive, by requiring the
occurance of the exact name of the module at the beginning of a line in
/proc/modules.
# module="pptp" ; grep "^$module " /proc/modules

Since the switch to netifd, proto handlers may always set the defaultroute
and provide dns server addresses, netifd will decide in the generic code
path whether the announced values are masked or not.
Additionally protocol handlers should not modify the routing tables themselves
and prevent any launched services from doing so.
Remove the additional defaultroute and peerdns option handling from the ppp.sh
protocol handler and rely on netifd to mask or not mask the values.
