The legacy map version based on the IPv6 Interface Identifier in
draft-ietf-softwire-map-03 was typically used by uncommenting the LEGACY
variable in the map.sh file, which is not ideal. A proper configuration
option is needed instead.
The IPv6 Interface Identifier format described in the draft was
eventually changed in RFC7597, but is still used by some major ISPs,
including in Japan.

Signed-off-by: Hans Dedecker <dedeckeh@gmail.com> [PKG_RELEASE increase]
In the package guidelines, PKG_VERSION is supposed to be used as
"The upstream version number that we're downloading", while
PKG_RELEASE is referred to as "The version of this package Makefile".
Thus, the variables in a strict interpretation provide a clear
distinction between "their" (upstream) version in PKG_VERSION and
"our" (local OpenWrt trunk) version in PKG_RELEASE.
For local (OpenWrt-only) packages, this implies that those will only
need PKG_RELEASE defined, while PKG_VERSION does not apply following
a strict interpretation. While the majority of "our" packages actually
follow that scheme, there are also some that mix both variables or
have one of them defined but keep them at "1".
This is misleading and confusing, which can be observed by the fact
that there typically either one of the variables is never bumped or
the choice of the variable to increase depends on the person doing the
change.
Consequently, this patch aims at clarifying the situation by
consistently using only PKG_RELEASE for "our" packages. To achieve
that, PKG_VERSION is removed there, bumping PKG_RELEASE where
necessary to ensure the resulting package version string is bigger
than before.
During adjustment, one has to make sure that the new resulting composite
package version will not be considered "older" than the previous one.
A useful tool for evaluating that is 'opkg compare-versions'. In
principle, there are the following cases:
1. Sole PKG_VERSION replaced by sole PKG_RELEASE:
In this case, the resulting version string does not change, it's
just the value of the variable put in the file. Consequently, we
do not bump the number in these cases so nobody is tempted to
install the same package again.
2. PKG_VERSION and PKG_RELEASE replaced by sole PKG_RELEASE:
In this case, the resulting version string has been "version-release",
e.g. 1-3 or 1.0-3. For this case, the new PKG_RELEASE will just
need to be higher than the previous PKG_VERSION.
For the cases where PKG_VERSION has always sticked to "1", and
PKG_RELEASE has been incremented, we take the most recent value of
PKG_RELEASE.
Apart from that, a few packages appear to have developed their own
complex versioning scheme, e.g. using x.y.z number for PKG_VERSION
_and_ a PKG_RELEASE (qos-scripts) or using dates for PKG_VERSION
(adb-enablemodem, wwan). I didn't touch these few in this patch.

Don't set the default firewall zone to wan if not specified to keep the
behavior aligned with other tunnel protocols like gre and 6rd.
If the interface zone is not specified try to get it from the firewall config
when constructing the procd firewall rule.
While at it only add procd inbound/outbound firewall rules if a zone is specified.

Setting encaplimit to a numerical value results into the value being
included as tunnel encapsulation limit in the destination option header
for tunneled packets.
Several users have reported interop issues as not all ISPs support the
destination option header containing the tunnel encapsulation limit
resulting into broken map connectivity.
Therefore drop the default encaplimit value for map tunnels so
no destination option header is included by default.

Be compatible with ISPs which don't support the destination option header containing
the tunnel encapsulation limit as reported in FS#1501.
Setting the uci parameter encaplimit to ignore; allows to disable the insertion
of the destination option header in the map-e packets.
Otherwise the tunnel encapsulation limit value can be set to a value from 0 till 255
by setting the encaplimit uci parameter accordingly.
If no encaplimit value is specified the default value is 4 as before.

Delete the map-t device when tearing down the map-t interface; as such
there's no conflict when the map-t interface comes up again when trying
to add the map-t device as the map-t device was still present
(Can not add: device 'map-wan6_4' already exists!).
Only call ifdown in teardown for map-e and lw6o4 map interfaces types
in order to suppress the trace "wan6_4 (6652): Interface wan6_4_ not found"

Note, that licensing stuff is a nightmare: many packages does not clearly
state their licenses, and often multiple source files are simply copied
together - each with different licensing information in the file headers.
I tried hard to ensure, that the license information extracted into the OpenWRT's
makefiles fit the "spirit" of the packages, e.g. such small packages which
come without a dedicated source archive "inherites" the OpenWRT's own license
in my opinion.
However, I can not garantee that I always picked the correct information
and/or did not miss license information.
