__mpath_connect() was part of our public ABI. Instead of removing
it completely, define it as a weak alias of the new mpath_connect__().
This way, programs linked against previous versions of libmpathcmd
will continue to work.
This shouldn't interfere with general symbol naming rules, as a weak
symbol won't override a library symbol of the same name.
