Message 58904 - Python tracker

I am ok with disallowing symlinks in rmtree() because if it were to be
allowed, the semantics are not clear. In addition, neither 'rmdir' nor
'rm -rf' delete the target directory. 

The attached patch would raise error if symbolic link is passed to
rmtree. Even though there is a parameter 'ignore_errors", I don't think
it should be used in suppressing symbolic link error. Comments?
