fixes build after 3ec63b8c

This package drops all incoming router advertisements except for the
default router with the best metric according to B.A.T.M.A.N. advanced.

Note that advertisements originating from the node itself (for example
via gluon-radvd) are not affected.

Also disabling TX checksums and not only allowing incoming packets without
checksum will provide another small speedup. As doing so would break wired
meshing with VXLAN-enabled nodes that require non-zero checksums, we will
wait a few days before this step.

Evaluating these rules before all the ICMPv6 rules improves wired mesh
throughput measurably.

Improves performance slightly.

On most devices, there is only a single LAN interface connected to all LAN
ports, so no bridge is necessary.

scripts/filesize.sh doesn't follow symlinks.

fc194bc autoupdater: uclient: add error handling in connection setup

marked as BROKEN for now as it is untested

related issue: #1099

fixes #442

Ensure packages get rebuilt when gluon.mk changes.

In addition to significant internal differences in check_site_lib.lua (in
particular unifying error handling to a single place for the upcoming
multi-domain support), this changes the way fields are addressed in site
check scripts: rather than providing a string like 'next_node.ip6', the
path is passed as an array {'next_node', 'ip6'}.

Other changes in site check scripts:
* need_array and need_table now pass the full path to the sub fields to the
subcheck instead of the key and value
* Any check referring to a field inside a table implies that all higher
levels must be tables if they exist: a check for {'next_node', 'ip6'} adds
an implicit (optional) check for {'next_node'}, which allows to remove many
explicit checks for such tables

libgluonutil is not usable outside the OpenWrt/LEDE environment anyways, so
it doesn't make much sense to make the CMakeLists.txt overly generic.

The domain configs are not checked yet, and not used for anything.

[Matthias schiffer: rebase, add a few more restrictions]

These helpers are no-ops for now, until the actual multi-domain support is
added.

[Matthias Schiffer: rebase]

Not useful by itself except for testing; will be used for multi-domain
support.

[Matthias Schiffer: rename script, use for initial configuration]

This should not convert JSON to a Lua table and back, as this loses the
distinction between arrays and objects, but as our site.conf is defined in
Lua anyways (for now), this can be fixed in a later revision.

[Matthias Schiffer: rename to gluon-show-site, rebase]

[Matthias Schiffer: change section name and commit message]

By basing the Lua gluon.site module on gluonutil_load_site_config(), the
config load implementation needs to changed only in a single place for
multi-domain support.
