Import several improvement from upstream:
* r2408,2409 - use SOCK_CLOEXEC for all sockets including PPtP,
web and telnet consoles, so that subprocesses like ip-up/down scripts
do not inherit such sockets;
* r2415 - avoid inadequate MTU undervalueing when bundle compression
and/or encryption configured but not negotiated;
f.e. PPPoE interface MTU could be set to 1490 instead of 1492 previously;
* r2482,2483 - improve client-side implementation of PPP-Max-Payload (RFC4638)
and do not limit "set pppoe max-payload {size}" to 1510
but use MTU of parent interface minus 8, as per RFC;
also, relax sanity check for "set link mtu/mru" in case of PPPoE,
so that it is possible to configure values like 1500 and over, if needed.
