Unionfs: copyup only if file is being written to
Before, we used to copyup on an open(2) call which used flags implying
writing (O_RDWR, O_WRONLY, O_APPEND). This meant that a file being opened
for writing, then immediately closed (without actually writing to the file),
will still have been copied up. Now, we don't copyup such files in ->open,
but defer the copyup till later. [Bug #591].

Unionfs: implement vm_operations->fault
As per recommendations made at LSF'08, a stackable file system which does
not change the data across layers, should try to use vm_operations instead
of address_space_operations. This means we now have to implement out own
->read and ->write methods because we cannot rely on VFS helpers which
require us to have a ->readpage method. Either way there are two caveats:
(1) It's not possible currently to set inode->i_mapping->a_ops to NULL,
because too many code paths expect i_mapping to be non-NULL.
(2) a small/dummy ->readpage is still needed because generic_file_mmap,
which we used in unionfs_mmap, still check for the existence of the
->readpage method. These code paths may have to be changed to remove the
need for readpage().

Unionfs: implement sendfile directly
Must implement sendfile, because we can no longer rely on
generic_file_sendfile: it needs the ->readpage address_space_operation
implemented, which we no longer have.

Unionfs: implement splice_read/write methods directly
Must implement splice_read/write directly, using VFS helpers, because we can
no longer rely on generic_file_splice_read/write: they need
address_space_operations implemented, which we no longer have.

VFS: rename do_splice_to/from to vfs_splice_* and export symbols
A stackable file system which uses vm_ops->fault, and does not implement
address_space_operations, cannot use generic_file_splice_read/write, but has
to implement ->splice_read/write itself. These two helper functions are
very useful to such a module.
