r20544: Change copy_file() to return NTSTATUS. This is in preparation of turning

close_file() to NTSTATUS as well.

I'm not sure I got all the error codes right, but as I've never come across a
smb_copy() call in all my Samba work, I'm leaving it at that. If I'm
absolutely bored, I will write a thorough torture test.

As far as I can see, Samba4 even does not have a libcli implementation for
it...  :-)
