the munin protocol.

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.

c2108276eb Improve parsing of commands and plugin names

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.

56bf90a6f8 muninlite: fix irqstats plugin 
The config() function of irqstats seems to contain a superfluous
semicolon, causing munin to choke on this plugin. This simple patch
fixes exactly that.
