collectd.conf(5): sigrok plugin: Improve markup.
use pkg-config to locate libmnl and configure netlink plugin
rrdtool plugin: Minor performance improvement.
Replace the value_list_to_string() function with a version which is optimized
for data sets with a single data source. The original function is still used
for data sets with multiple data sources. This allows to reduce the number of
calls to snprintf() in this (very common) case, resulting in ~2% speedup.

statsd_parse_value() will write to (value_t).gauge, so don't read from another

Fix pointer confusion for nested attribute parsing

the resulting attribute payload should be stored in

update build system to reflect switch to libmnl
"./configure" was previously checking for libnetlink and setting
"-lmnl" if found, which was obviously calling for trouble. With
this patch, the last references to libnetlink are dead and buried.
NB: linux/netlink.h and friends are still included here and there
though, but these are not related to libnetlink.
