By default odhcp6c asks for a default list of options; the config option
defaultreqopts allows to tweak this behavior.
When set to 0 odhcp6c will not ask for any options except for the options
specified in the reqopts config option.

Add sendopts config support allowing to add options in sent DHCPv6 packets.
Options can be configured as follows :
uci set network.wan6.sendopts="sntpservers:3001:3001::1,3001:3001::2 11:00000000000000000000006674692F 0x3e8:ABCDEF"

Add option keep_ra_dnslifetime which will preserve the received
lifetime for RDNSS and DNSSL RA records and not overwrite it
by the RA router lifetime as specified in RFC6106.
This allows to accept RDNNS records from RAs that don't announce
a default route by setting router lifetime to 0 in the RAs.

Some ISP seem to only do stateful DHCPv6 and not sending RAs.
This is technically broken because plain DHCPv6 doesn't carry routes.
We work around here by faking a default route to the DHCPv6 server
if we do not receive a useful RA from the ISP.
This workaround can be turned off with: option fakeroutes 0
