Switch the default WARNS level for sbin/ to 6.

Submitted by: Ulrich Spörlein

Make this WARNS=6 clean by renaming the variable 'err' to 'error'
in order not to shadow err(3).

Tested by: make universe

Use GEOM OAM api to retrive list of configured ccd devices.

Link against libgeom.

Fix various details so we get to WARNS=3.
Center operation on unit number rather than path name.

Default to WARNS=2.
Binary builds that cannot handle this must explicitly set WARNS=0.
