If we do not hold a valid stateid that is open for writes, there is little
point in doing an extra open of the file, as the RFC does not appear to
mandate this...
Make setattr use the correct stateid if we're holding mandatory byte
range locks.

Add nfs4_acl field to the nfs_inode, and use it to cache acls. Only cache
acls of size up to a page. Also prepare for up to a page of acl data even
when the user doesn't pass in a buffer, as when they want to get the acl
length to decide what size buffer to allocate.

Client-side support for NFSv4 ACLs. Exports the raw xdr code via the
system.nfs4_acl extended attribute. It is up to userspace to decode the acl
(and to provide correctly xdr'd acls on setxattr), and to convert to/from
POSIX ACLs if desired.
This patch provides only the read support.

Add {get,set,list}xattr methods for nfs4. The new methods are no-ops, to be
used by subsequent ACL patch.

ACL support will require supporting additional inode operations in v4
(getxattr, setxattr, listxattr). This patch allows different protocol versions
to support different inode operations by adding a file_inode_ops to the
nfs_rpc_ops (to match the existing dir_inode_ops).

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!
