Subject: cleanup finddisks and findblockdevices API

Due do to some old remaining cruft, the API for
finddisks and findblockdevices was needlessly complicated.
The only thing really needed is some ability to control what goes
between entries.  Al the other stuff (string at the end, control of
newlines) was pointless.
