  * checker+repairer: Improve deep-check resilience in the presence of unrecoverable subdirectories
  
  Previously, when a deep-check operation found an unrecoverable subdirectory, an
  exception was raised. The whole operation was then stopped and the deep-check
  report was lost.
  
  This patch improves this behaviour by allowing the operation to continue while
  correctly recording the repair failure in the deep-check report.
  
  The CLI now also displays the name of each file on which a repair was attempted.

[bundled zetuptoolz: prefer locally-available distributions over remotely-downloaded distributions above all

 This fixes #1233. Actually the previous patches—[20101103034740-93fa1-9df33552497282eb72a84e5b434d035974bf2dbb] and [20101117080828-92b7f-dc0239f30b26e7e5d40b228114fb399c1e190ec5]—fixed it, but with them zetuptoolz would download a higher-numbered distribution from the net instead of using the locally-available (fake) pycryptopp-0.5.24, thus preventing the tests from passing. This patch changes that behavior (which is an improvement in its own right) and also fixes a bug in the tests.

 Whenever Free Software/Open Source legal folks are examining the Tahoe-LAFS source code, it seems like there has to be a discussion and documentation about every single licensing declaration. Since this one is (was) permissive, then you would think it could be avoided, but I'm not betting on it. We would probably have to install a copy of the MIT licence into every one of the "copyright" files under the debian/ subdirectory, for example. So: let's just let hashbasedsig.py be licensed the same way as the rest of Tahoe-LAFS.

 For one thing, this makes missing-dependency failures into DistributionNotFound errors instead of ImportErrors, which might be more useful to the user. For another thing, if someone is using distributions that were installed with --multi-version, then they might be not importable until after require_auto_deps() has been run. (The docs claim that this would be the case, but we don't have an example of this happening at this time.)

 * repairer (really the uploader) reads beyond end of input file (Uploadable)
 * new-downloader does not tolerate overreads
 * uploader does lots of tiny reads (inefficient)
 
 This fixes the last two. The uploader still does a single overread at the end
 of the input file, but now that's ok so we can leave it in place. The
 uploader now expects the Uploadable to behave like a normal disk
 file (reading beyond EOF will return less data than was asked for), and now
 the new-downloadable behaves that way.
