SVN rev 207133 on 2010-04-23 19:35:07Z by mjacob
This is an MFC of 205847, 204071, 196580 and 196579
------------------------------------------------------------------------
Change how multipath labels are created and managed. This makes it easier
to support various storage boxes which really aren't active-active.
We only write the label on the *first* provider. For all other providers
we just "add" the disk. This also allows for an "add" verb.
A usage implication is that you should specificy the currently active
storage path as the first provider.
Note that this does not add RDAC-like functionality, but better allows for
autovolumefailover configurations (additional checkins elsewhere will support
this).
------------------------------------------------------------------------
- Style fixes.
- Prefer strlcpy() over strncpy().
------------------------------------------------------------------------
There's no need for checking result of M_WAITOK allocation.
------------------------------------------------------------------------
Fix an obvious topology lock leak.
