Update to 1.9.2.

Release 1.9.2 (2012-07-03)
----------------------------

Notable Bugfixes
''''''''''''''''

- Several regressions in support for reading (`#1636`_), writing/modifying
  (`#1670`_, `#1749`_), verifying (`#1628`_) and repairing (`#1655`_, `#1669`_,
  `#1676`_, `#1689`_) mutable files have been fixed.
- FTP can now list directories containing mutable files, although it
  still does not support reading or writing mutable files. (`#680`_)
- The FTP frontend would previously show Jan 1 1970 for all timestamps;
  now it shows the correct modification time of the directory entry.
  (`#1688`_)
- If a node is configured to report incidents to a log gatherer, but the
  gatherer is offline when some incidents occur, it would previously not
  "catch up" with those incidents as intended. (`#1725`_)
- OpenBSD 5 is now supported. (`#1584`_)
- The ``count-good-share-hosts`` field of file check results is now
  computed correctly. (`#1115`_)

Configuration/Behavior Changes
''''''''''''''''''''''''''''''

- The capability of the upload directory for the drop-upload frontend
  is now specified in the file ``private/drop_upload_dircap`` under
  the gateway's node directory, rather than in its ``tahoe.cfg``.
  (`#1593`_)
