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: prevent races in unionfs_fault
vm_ops->fault may be called in parallel. Because we have to resort to
temporarily changing the vma->vm_file to point to the lower file, a
concurrent invocation of unionfs_fault could see a different value. In this
workaround, we keep a different copy of the vma structure in our stack, so
we never expose a different value of the vma->vm_file called to us, even
temporarily. A better fix (already tested) would be to change the calling
semantics of ->fault to take an explicit file pointer.
