Subject: [PATCH] Feature: New config block to define YP directories

Adds a new config block, <yp-directory> with the mandatory "url"
attribute and optional <option> entries in the block:

  <yp-directory url="http://example.org/yp-cgi">
    <option name="timeout" value="5" />
    <option name="touch-interval" value="45" />
  </yp-directory>
