02c763c4ab odhcp6c: Revert to slightly modified version of old behaviour 
Latest changes broke source-restriction of on-link routes. Restoring
old-behaviour but adding correct source-restrictions which prevents
the offlink handler to remove the on-link route.

e1c5111997 6rd: Make don't fragment bit (df) a configurable variable 
Make the IPv4 "do not fragment" bit a configurable variable for the 6rd
tunnel interface as the bit should not be set in the encapsulating IPv4
header according to RFC3056.
On top the config variable allows to enable/disable path mtu discovery
for tunnel interfaces.
Config variable can be passed to netifd as tunnel config support is
already present for the "do not fragment" bit.

b5a4fb1c95 6rd: Clear correct IPv6 address bits in 6rdcalc 
The correct bits are now cleared in the IPv6 address as the shift
value to the correct byte in the IPv6 address was wrong. Depending
on the stack values this could result in a hanging 6rdcalc program
due to an endless loop.

fe7c236a06 6relayd: prevent build on AVR32 
AVR32 misses a bunch of updated syscalls, including timerfd_create()
which is used by 6relayd. Since that requires Linux/libc changes, just
prevent building it for now.
