Fix broken DHCPv6 servers which provide the server unicast option but
do not reply on DHCPv6 renew messages directed to the IPv6 address
contained in the server unicast option whihc results in broken IPv6
connectivity.

Be compatible with ISPs which don't support the destination option header containing
the tunnel encapsulation limit as reported in FS#1501 for dynamic created ds-lite/map
interfaces.
Setting the uci parameter encaplimit_dslite/map to ignore; allows to disable the insertion
of the destination option header for the dynamic created ds-lite/map interface.
Otherwise the tunnel encapsulation limit value can be set to a value from 0 till 255
by setting the encaplimit_dslite/map uci parameter accordingly.

Support configuration in the form...
list ip6prefix 2001:db8:1234::/64
list ip6prefix 2001:db8:5678::/64
... to allow specifying multiple additional IPv6 prefixes.
Implements feature request FS#1361.

Don't append an empty sendopts value as odhcp6c bails out
immediately on an empty -x option triggering an infinite start
loop of odhcp6c

Commit a26045049b added support for sendopts as a string; since multiple
sendopts values can be specified it makes more sense to model it as a
list of strings.

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"

Extendprefix is typically used to extend an IPv6 RA prefix from a mobile
wan link to the LAN; such scenario requires correct RA prefix settings
like the on link flag not being set.
However some mobile manufacter set the RA prefix on link flag which breaks
basic IPv6 routing.
Work around this issue by filtering out the route being equal to the
extended prefix.

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.

* Change git packages to xz
* Update mirror checksums in packages where they are used
* Change a few source tarballs to xz if available upstream
* Remove unused lines in packages we're touching, requested by jow- and blogic
* We're relying more on xz-utils so add official mirror as primary source, master site as secondary.
* Add SHA256 checksums to multiple git tarball packages
