While procps_diskstat_ref and procps_diskstat_unref were declared
they actually weren't implemented in the library. Linking some
binary that used these functions gave the following errors:
CCLD vmstat
vmstat.o: In function `disksum_format':
vmstat.c:719: undefined reference to `procps_diskstat_unref'
vmstat.o: In function `diskformat':
vmstat.c:591: undefined reference to `procps_diskstat_unref'
[ but most definitely not all of them by a long shot ]

The calls for reading diskstat have been moved out of
sysinfo and into new files diskstat.[ch] These new
library calls follow the standard pattern for the
new libprocps.
vmstat is updated to use the new API and also got
the weighted IO time added.
vmstat -p previously would only show partitions, not
disks. There does not appear to be any good reason to
artifically deny a user to use this command on a disk,
rather than a partition so this restriction was lifted.
I also realised using int for devid means you can send
the library negative numbers, the index uses unsigned int.
Other similiar calls will need to be fixed too.
