1b43f16454 Network interface names: tolerate more than one hyphen 
Previously the handling of network interface names allowed something
like "foo-bar", but failed over "foo-bar-baz".

Thanks to Kai-Uwe Eckhardt.

dc242d3631 Plugin cpu: fix handling of more than ten CPUs 
Previously only CPU entries with a single digit (0..9) were parsed.
The improved regular expression simplifies the calculation of the CPU
count, since the combined entry ("cpu" without digits) is skipped.

f4518e5375 Change name of executable from "munin-node" to "muninlite" 
Previously MuninLite tried to create a drop-in-replacement for
munin-node by using the same name.  But MuninLite behaves differently
and may even be used in parallel to a regular munin-node setup on a host,
thus it should use a distinct name.
