Update "scripts: metadata: always resolve dependencies through provides
list" to new version.

Allow to use PROVIDES to replace existing packages.

The added debug information is stripped of during packaging, so it does not
increase the package size. It does however slightly change offsets in the
code, preventing the weird ash segfaults we've been seeing. Also, if the
issue returns, we'll have debug information matching the coredumps.

This patch got lost in the OpenWrt -> LEDE transition and fixes flash
writes on new UBNT PicoStations.

Backport another sysupgrade patch.

Updates batman-adv and alfred to 2017.1. This also allows us to drop our
last batman-adv patch.

The staged sysupgrade allows to properly unmount the rootfs before writing
the new partitions. This will fix upgrades losing configuration when
parition sizes change on x86 and similar image types.

Fixes meshing over 802.11s.

This will ensure that gluon-site and gluon-autoupdater are rebuilt
correctly when GLUON_RELEASE or GLUON_BRANCH change.

Also remove our own no_rebroadcast patch, as batman-adv v2016.5 now has a
more sophisticated rebroadcast suppression that should work automatically
in the most relevant cases.

Fixes a build issue when switching targets.

The ar71xx-tiny target sets CONFIG_CLEAN_IPKG, which would delete opkg
control files required for user creation. Fix image generation and the user
creation script.

Fixes #1012

ath10k has to switch the regulatory domain when switching the default
country when ATH_USER_REGD is enabled. This is for example important when
switching from country US (FCC) to DE (ETSI). The ath implementation will
use ath_reg_dyn_country_user_allow to check if this is allowed.

Unfortunately, this function always seems to return false to
ath_reg_notifier_apply even when ATH_USER_REGD is enabled. But it must
actually always accept the requests from the user (when ATH_USER_REGD is
enabled) to correctly set the conformance test limits in the ath10k binary
blob.

Not doing it will sometimes allow too high transmit powers on edge channels
for correctly calibrated devices outside their default regulatory domain.

Closes #844

Fixes #961

Backport a few patches to allow sysupgrades on mmcblk and similar block
devices.

Fixes #975

This lifts batman-adv and alfred to version 2016.4.
