Currently we return -ENOMEM for every single failure to create a new auth.
This is actually accurate for auth_null and auth_unix, but for auth_gss it's a
bit confusing.
Allow rpcauth_create (and the ->create methods) to return errors. With this
patch, the user may sometimes see an EINVAL instead. Whee.

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.

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).

Ensure that we fix up the missing fields in the nfs_mount_data with
sane defaults for older versions of mount, and return errors in the
cases where we cannot.
Convert a bunch of annoying warnings into dprintks()
Return -EPROTONOSUPPORT rather than EIO if mount() tries to set NFSv3
without it actually being compiled in.

This patch makes some needlessly global identifiers static.

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!
