[issue12715] Add symlink support to shutil functions

[Petri Lehtinen]

New submission from Petri Lehtinen <petri at digip.org>:

The shutil.copytree() function aknowledges symlinks when given
the symlink=True argument. Other shutil functions should do this
too:

copymode(src, dst, symlinks=True)
   If both src and dst are symlinks, copy the source symlink mode
   to the destination symlink. If only one of them is a symlink,
   dereference it normally.

copystat(src, dst, symlinks=True)
   If both src and dst are symlinks, copy the statinfo of the
   source symlink to the destination symlink. If only one of them
   is a symlink, dereference it normally.

copy(src, dst, symlinks=True)
   If the src argument is a symlink, copy the source symlink
   instead of dereferencing it.

   Problem: What if dst is a symlink to a directory? Should it be
   replaced or should the symlink copied inside that directory?

copy2(src, dst, symlinks=True)
   Like copy(src, dst, symlinks=True), but copy the metadata too.
   The same problem applies.
