build: ignore deactivated feeds

Reuse outdoor device logic for setup mode interface selection, plus some cleanup

The OpenWrt feeds.conf.defaults contains some feeds that are commented out
and not active. Such feeds will be returned by the default_feeds.sh script
anyway and causing pseudo feeds. Limit the script to only return active
feeds, by filtering out lines starting with '#'.
This usually only applies to the OpenWrt master branch.

As a partial fix to #496, do not touch the MAC address of the WAN
interface when using VXLANs (as only the MAC address of the VXLAN
interface matters to batman-adv).

This reverts commit 2a8943e5.

.SILENT gets passed down to OpenWrt make as -s through MAKEFLAGS. This
hides certain messages from the build log with V=s.

Certain error message (for example invalid package names) were emitted
once for each device.

gluon-mesh-vpn-fastd: clean up peers and groups on update

config_ifname was renamed to setup_ifname in Gluon v2015.1.

On PoE-powered devices, we usually want to use WAN for the setup mode.
As all outdoor devices are PoE-powered, we can reuse this function. This
switches the setup mode interface for new installations / after config
reset on a few devices that were missing in this list before.

- Use util.find_phy()
- Stop foreach() as soon as the result is known

The 'preserve' flag can be used to mark a peer so it is not removed or
modified on upgrades. In addition, groups containing preserved peers are
not removed.

Compile-tested: all targets

gsub() returns the number of matches as its second return value. This
was unintendedly passed through by the util functions trim() and
node_id(). It can be presumed that this had no effect in practice, but
it can lead to surprising output when passing values to print() for
debugging.

The precedence of different package lists was broken since #1876,
disallowing removal of GLUON_FEATURES packages via GLUON_SITE_PACKAGES.

Including all package selections, both implicit defaults and explicit
handling in Gluon, the order of precedence is now the following:

1.  OpenWrt defaults (including target-specific defaults)
2.  Device-specific packages from OpenWrt
3.  Generic default packages (from target/generic)
4.  Target default packages (target/$(GLUON_TARGET))
5.  Removal of opkg for tiny targets
6.  Packages derived from GLUON_FEATURES + GLUON_FEATURES_$(class)
7.  GLUON_SITE_PACKAGES
8.  GLUON_SITE_PACKAGES_$(class)
9.  Device-specific packages from target/$(GLUON_TARGET)
10. Device-specific packages from GLUON_$(device)_SITE_PACKAGES

This also contains various pieces of cleanup:

- No hardcoded order of device classes for target_config.lua arguments
  anymore (in fact, the Makefile doesn't know anything about device
  classes now)
- target_conifg_lib.lua only hardcodes the fallback class for x86, no
  other occurences of specific class names
- Feature -> package list mapping is moved from Makefile to the Lua code
  as well (still implemented in Shell though)

Allows to append additional commands, for example using `||`.

Closes #1993

(cherry picked from commit 7f3a3042)

(cherry picked from commit 4bfcd6ae)

Allows reconfigurtion of remote syslog from within site.conf.

Conflicts with the gluon-web-logging package as user made changes
will be overwritten, because this package will reconfigure the syslog
destination on every upgrade.

Resolves #1845
