Hauke Mehrtens 80b58a9db6 hostapd: Update to version 2.8 (2019-04-21)
This also syncs the configuration files with the default configuration
files, but no extra options are activated or deactivated.

The mesh patches were partially merged into hostapd 2.8, the remaining
patches were extracted from patchwork and are now applied by OpenWrt.
The patches still have open questions which are not fixed by the author.
They were taken from this page:
https://patchwork.ozlabs.org/project/hostap/list/?series=62725&state=*

The changes in 007-mesh-apply-channel-attributes-before-running-Mesh.patch
where first applied to hostapd, but later reverted in hostapd commit
3e949655ccc5 because they caused memory leaks.

The size of the ipkgs increase a bit (between 1.3% and 2.3%):

Subject: [PATCH 4/7] mesh: do not set offchanok on DFS channels in non-ETSI
mac80211 does not allow mgmt tx to use off channel on
DFS channels in non-ETSI domain, because it will invalidate
CAC result on current operating channel.
(mac80211 commit: 34373d12f3cbb74960a73431138ef619d857996f)
Hence don't set offchanok for mgmt tx in case of DFS channels
in non-ETSI.
