This adds a variant of refpolicy that builds the modular form of the
policy. While this requires more memory on the target device, along with
some tricks to deal with OpenWrt's volatile /var directory, it is useful
for experiementing with SELinux policy.

The previous commit broke opkg in a way that it would no longer

On devices with small amounts of RAM, zram-swap fails to initialise due to the
default compression algorithm (lzo-rle). Startup example on an AirGrid M2, with
32 MiB of RAM:
root@airgrid:/etc/config# /etc/init.d/zram start
zram_start: activating '/dev/zram0' for swapping (13 MegaBytes)
zram_reset: enforcing defaults via /sys/block/zram0/reset
sh: write error: Out of memory
mkswap: image is too small
swapon: /dev/zram0: Invalid argument
root@airgrid:/etc/config#
Fix this by defaulting to traditional lzo, which works fine and is always
available.

The key folder is used by `opkg` and `usign` to store and retrieve
trusted public keys. Using `opkg-key` outside a running device is
unfeasible as the key folder is hard coded to `/etc/opkg/keys`.
This commit adds a variable OPKG_KEYS which defaults to `/etc/opkg/keys`
if unset, however allows set arbitrary key folder locations.

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.

So lets remove the currently bogus `respawn_retry` variable (it wasn't

of 5 service restarts which could be now overriden via system's UCI
