nfs4: fix channel attribute sanity-checks
The sanity checks here are incorrect; in the worst case they allow

They're also over-reliant on the preprocessor.

NFSv4.1: Use more sensible names for 'initialize_mountpoint'
The initialize_mountpoint/uninitialise_mountpoint functions are really about
setting or clearing the layout driver to be used on this filesystem. Change

NFSv4.1: pnfs: add LAYOUTGET and GETDEVICEINFO infrastructure
Add the ability to actually send LAYOUTGET and GETDEVICEINFO. This also adds
in the machinery to handle layout state and the deviceid cache. Note that
GETDEVICEINFO is not called directly by the generic layer. Instead it
is called by the drivers while parsing the LAYOUTGET opaque data in response
to an unknown device id embedded therein. RFC 5661 only encodes
device ids within the driver-specific opaque data.

NFS: client needs to maintain list of inodes with active layouts
In particular, server reboot will invalidate all layouts.
Note that in order to have an active layout, we must get a successful response
from the server. To avoid adding that machinery, this patch just includes a
stub that fakes up a successful return. Since the layout is never referenced
for io, this is not a problem.

NFS: ask for layouttypes during v4 fsinfo call
This information will be used to determine which layout driver,
if any, to use for subsequent IO on this filesystem. Each driver
is assigned an integer id, with 0 reserved to indicate no driver.
The server can in theory return multiple ids. However, our current
client implementation only notes the first entry and ignores the
rest.

NFS: change stateid to be a union
In NFSv4.1 the stateid consists of the other and seqid fields. For layout
processing we need to numerically compare the seqid value of layout stateids.
To do so, introduce a union to nfs4_stateid to switch between opaque(16 bytes)
and opaque(12 bytes) / __be32
