Daniel Golle 78f1974bc5 hostapd: update packaging and patches
Clean up conflicts/provides/depends hell and add PROVIDES for
eapol-test variants while at it.
Update mesh-DFS patchset from Peter Oh to v5 (with local fixes) which
allows to drop two revert-patches for upstream commits which previously
were necessary to un-break mesh-DFS support.

Subject: [PATCH 16/18] mesh: fix channel switch error during CAC
Mesh interface has used its channel parameters that configured
during its initialization even after channel switched due to
DFS radar detection during CAC which caused channel switch error.
This change fixes the error by updating its channel parameters
when channel's been changed from initial one.
