Thomas Huehn 55e530747f collectd: upgrade package collectd to version 5.8.0 
This patch upgrades the collectd package from 5.7.2 to 5.8.2.
All openwrt patches got either updated or deleted in case they
are already included into upstream collectd.
The new collectd 5.8.0 package compiles and got tested on current
lede trunk with latest luci on an PCengines APU. All default plugins
(enabled via Openwrt  Makefile) - so also iwinfo - are running fine
with the new version.

Signed-off-by: Thomas Huehn <thomas@net.t-labs.tu-berlin.de>

Amended with the following changes:

* preserve git file history by avoiding unnecessary patch renames
* mark new plugins introduced with 5.8 branch as disabled

Compile tested all plugins with ipq806x

+If no configuration if given, the B<iwinfo>-plugin will collect data from all

+collect all interfaces I<except> a few ones. This option enables you to do
