Comment 2 for bug 315774

Quoting the developer commit:
==================

[Bug 6022] smbc_urlencode and smbc_urldecode were not exported
- Since the revamp of libsmbclient, there has still been an external
  declaration for smbc_urlencode and smbc_urldecode in libsmbclient.h, yet
  those functions were renamed and made private. The two choices were to
  remove the function names from libsmbclient.h or to make them public
  again. The reported requested that they be public. This commit makes it so.
