check_smart

The feature was requested in #30 . This PR adds the possibility to use 3ware,N and cciss,N drives in combination with the global -g parameter.

Furthermore this PR adjusts the output of the plugin when the -g is used in combination with hardware raid controllers. Instead of showing the logical device name (/dev/sda for example), the plugin will now show the controller with drive number:

# ./check_smart.pl -g /dev/sda -i 'cciss,[1-3]'
OK: [cciss,1] - Device is clean --- [cciss,2] - Device is clean --- [cciss,3] - Device is clean|

Add Reported_Uncorrect and Reallocated_Event_Count to default raw list. As of 6.5 the following SMART attributes are by default checked and may result in alert when threshold (default 0 is reached):

'Current_Pending_Sector,Reallocated_Sector_Ct,Program_Fail_Cnt_Total,Uncorrectable_Error_Cnt,Offline_Uncorrectable,Runtime_Bad_Block,Reported_Uncorrect,Reallocated_Event_Count'

Added -q / --quiet parameter. When multiple drives are checked using the -g parameter, all drives appear in the output (no matter the state). Using the additional -q parameter will only show the drives with failing drives and omit the drives in OK state.

Furthermore the dependency on the Perl module utils.pm (coming from either monitoring-plugins-common or nagios-plugins-common packages) was removed. Only very few functions from this module were actually used and these were very basic. It makes more sense here to be a fully standalone plugin.
