smbclient reparse point symlink parameters reversed
===================================================

A bug in smbclient caused the 'symlink' command to reverse the
meaning of the new name and link target parameters when creating a
reparse point symlink against a Windows server.

This only affects using the smbclient 'symlink' command against
a Windows server, not a Samba server using the UNIX extensions
(the parameter order is correct in that case) so no existing
user scripts that depend on creating symlinks on Samba servers
need to change.

As this is a little used feature the ordering of these parameters
has been reversed to match the parameter ordering of the UNIX
extensions 'symlink' command. This means running 'symlink' against
both Windows and Samba now uses the same paramter ordering in both
cases. 

The usage message for this command has also been improved to remove confusion.
