FS-Cache: Make kAFS use FS-Cache

The attached patch makes the kAFS filesystem in fs/afs/ use FS-Cache, and
through it any attached caches. The kAFS filesystem will use caching
automatically if it's available.

AFS: implement basic file write support

Implement support for writing to regular AFS files, including:

(1) write

(2) truncate

(3) fsync, fdatasync

(4) chmod, chown, chgrp, utime.

AFS writeback attempts to batch writes into as chunks as large as it can manage
up to the point that it writes back 65535 pages in one chunk or it meets a
locked page.

Furthermore, if a page has been written to using a particular key, then should
another write to that page use some other key, the first write will be flushed
before the second is allowed to take place. If the first write fails due to a
security error, then the page will be scrapped and reread before the second
write takes place.

If a page is dirty and the callback on it is broken by the server, then the
dirty data is not discarded (same behaviour as NFS).

Shared-writable mappings are not supported by this patch.

[AFS]: Add support for the CB.GetCapabilities operation.

Add support for the CB.GetCapabilities operation with which the fileserver can
ask the client for the following information:

(1) The list of network interfaces it has available as IPv4 address + netmask
plus the MTUs.

(2) The client's UUID.

(3) The extended capabilities of the client, for which the only current one
is unified error mapping (abort code interpretation).

To support this, the patch adds the following routines to AFS:

(1) A function to iterate through all the network interfaces using RTNETLINK
to extract IPv4 addresses and MTUs.

(2) A function to iterate through all the network interfaces using RTNETLINK
to pull out the MAC address of the lowest index interface to use in UUID
construction.

RxRPC keys are added to the session keyring with the klog program. open() and
other VFS operations then find this ticket with request_key() and either use
it immediately (eg: mkdir, unlink) or attach it to a file descriptor (open).

Linux-2.6.12-rc2

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
