This corrects the truncating of negative values in the diskstats plugin
and calculates its value based on the evidence that this is a overflow
value.

This patch was created by ksmadsen in
http://munin-monitoring.org/ticket/1275

The description provided was:

I've traced this problem to the fact that on the RH kernel we are using,
the rd_ticks/wr_ticks in /sys/block/*/stat are 32-bit numbers, so when
the ticks wraps, a negative value is reported.

Looking at the kernel source code, the tick counters are internally all
64-bit, but when they are read from the stat file, the output is limited
to 32-bits.

Clean field names

Non-clean field names cause problems with drawing, e.g. when there are spaces
or dashes in the process name. This commit cleans the field name by using the
appropriate support module. For more information, see:
