Using perflib is substantially faster and more reliable than using WMI to
retrieve Windows performance counter data.

The old names were hard to read, but had to be named as such to work with
the WMI library. Now that raw performance counter data are used instead of
WMI, we are free to name the data structs freely.

The perflib-based access code replaces WMI and is substantially more efficient
and stable, leading to fewer collection timeouts in the mssql collector.
