<p>Executes the rebuild backup action.</p>
<p>This function exists mainly to recreate a disc that has been
"trashed" due to media or hardware problems. Note that the
"stage complete" indicator isn't checked for this action.</p>
<p>Note that the rebuild action and the store action are very similar.
The main difference is that while store only stores a single day's
staging directory, the rebuild action operates on multiple staging
directories.</p>

<p>Finds the set of directories to be included in a disc rebuild.</p>
<p>A the rebuild action is supposed to recreate the "last
week's" disc. This won't always be possible if some of the staging
directories are missing. However, the general procedure is to look back
into the past no further than the previous "starting day of
week", and then work forward from there trying to find all of the
staging directories between then and now that still exist and have a
stage indicator.</p>

<dt>Parameters:</dt>

<li><strong class="pname"><code>config</code></strong> - Config object.</li>
</ul></dd>
<dt>Returns:</dt>
<dd>Correct staging dir, as a dict mapping directory to date suffix.</dd>

<li><code><strong class='fraise'>IOError</strong></code> - If we do not find at least one staging directory.</li>
