OpenWrt used to ship hardcoded defaults for lcp-echo-failure and
lcp-echo-interval in the non-uci /etc/ppp/options file.
These values break uci support for *disabling* LCP echos through
the use of "option keepalive 0" as either omitting the keepalive
option or setting it to 0 will result in no lcp-echo-* flags
getting passed to the pppd cmdline, causing the pppd process to
revert to the defaults in /etc/ppp/options.
Address this issue by letting the uci "keepalive" option default
to the former hardcoded values "5, 1" and by removing the fixed
lcp-echo-failure and lcp-echo-interval settings from the
/etc/ppp/options files.

to inhibit peer DNS servers in the configuration.

PPP daemon can be put into persist mode meaning the
daemon will not exit after a connection gets terminated
but will instead try to reopen the connection.
The re-initiation after the link has been terminated
can be controlled via holdoff; this is helpfull in
scenarios where a BRAS is in denial of service mode
due to link setup requests after a BRAS has gone down
Following uci parameters have been added :
persist (boolean) : Puts the ppp daemon in persist mode
maxfail (integer) : Number of consecutive fail attempts which
puts the PPP daemon in exit mode
holdoff (interget) : Specifies how many seconds to wait
before re-initiating link setup after it has been terminated

Adds PPP unnumbered support via the parameter unnumbered which points to a logical OpenWRT interface.
The PPP proto shell handler will "borrow" an IP address from the unnumbered interface (if multiple
IP addresses are present the longest prefix different from 32 will be "borrowed") for which a host
interface dependency will be created. Due to the host interface dependency the PPP unnumbered interface
will only "borrow" an IP address from an interface which is up.
The borrowed IP address will be shared as local IP address by the PPP daemon and no other local IP
will be accepted from the peer in the IPCP negotiation.
A typical use case is the usage of a public IP subnet on the Lan interface which will be shared
by the PPP interface as local IP address.

Enables last error support for the PPP protocol handlers.
In generic teardown the PPP daemon exit code is translated into
a self explaining error string which is set as interface error
by proto_notify_error in case of failure.

The previous implementation of the "host-uniq" option used plain strings for
passing the value to pppd which made it impossible to specify binary data.
Switch the format to a hex encoded string to support binary data.

Port Debians adaptive LCP echo patch to pppd, make it configurable with UCI
and enable it by default.
When adaptive LCP echo is enabled, LCP echo requests are only sent if the
link is idle, this avoids the common situation where a congested PPP link
(e.g. during torrenting) is falsely detected as disconnected because the
LCP replies are not received in time.
Also bump the copyright year in the Makefile, remove a redundant maintainer
entry and fix the shell processing of the keepalive option when the two-
value syntax is used.

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.

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.

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.
