On my system the attribute DEVTYPE was not set. The plugin could not
read any data and the function call blocked forever on this function and did
not returned. By removing it, all block devices under `/sys/class/block`
were checked.

Block devices that do not support SMART were not evaluated. The
collected displays the following message.

smart plugin: checking SMART status of /dev/loop4.
smart plugin: unable to open /dev/loop4.

If you do not like this message, you could only enable device in the uci that
does support SMART.

Currently the values are stored in the ubi plugin as data source type
`counter`. But this makes no sense, because the values change very slowly
and I don't want to know the rate of change. It is better to store the
value as data source type `gauge`. Then I can see the current value.

Adjust the reaction to a polling interval timestamp that references
to a past time.

Past timestamps can happen when ntpd adjusts router's time after network
connectivity is obtained after boot. Collectd shows warnings for each plugin
as it tries to enter new values with the same timestamp as the previous one.

This patch adjusts the next polling time to be now+2 seconds for the main
loop and for the plugin-specific read loops. That avoids the warnings, but
does not overreact in case there are shorter polling intervals or the time
gets adjusted for other reasons.

Additionally some debug statements are aded, but they are visible only
when --enable-debug configure option is used in Makefile.

If you want to register more than one lua plugin, you cannot start the
collectd.

You get always the error message:

"The read function "lua/(null)" is already registered. Check for
duplicates in your configuration!"

This is not what I expect and what the documenation says.
With this change it is now possible to registrate more then one lua
Script.

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.

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.

Uptime plugin fails to adjust for system time changes after boot.
As Openwrt/LEDE routers usually do not have a RTC, the system time
gets adjusted with NTP possibly after collectd has already started.
But collectd continues to use the initial time set by 'sysfixtime',
which can lead to incorrect uptime calculations.

Apply a proposed fix from upstream that uses /proc/uptime

Some collectd plugins launch third-party plugins that have variation in
initialisation time (like libpcap). Recently (since kernel bump to 4.1)
the DNS plugin has been causing collectd to crash semi-randomly at startup
on MIPS based WNDR3700.

Debugging led to realisation that the DNS plugin seems to require at least
0.1s time to start, before the first data reading attempt starts.

By default, the first data read cycle starts immediately, while apaprently
some of the plugins may still be asyncronously initialising. To make things
safe, this patch adds 1 second delay before the first data read cycle.

Change the interface plugin to operate with collectd's default way for Linux
instead of trying to use BSD functionality with patches.

Openwrt's collectd Makefile has set "enable-getifaddrs" option since r7980
(in 2007, no explanations given for the reasons to add that config option),
causing the addition of 110-net-device-stats.patch in 2010 to fix things,
and then later (with 5.4.1 upgrade in 2014) 150-fix-interface-af-link
to undo BSD-specific changes in collectd code meant for only BSD systems
(as AF_LINK does not exist in Linux).

Revert to collectd's intended way in Linux by removing the config option
and deleting the two corresponding patches.

The same data fieds should be provided, so there is no visbile change to users.
