db4 bug fix update

Updated db4 packages that fix a database verification bug are now
available.

The Berkeley Database (Berkeley DB) is a programmatic toolkit that
provides embedded database support for both traditional and
client/server applications. The Berkeley DB includes B+tree, Extended
Linear Hashing, Fixed and Variable-length record access methods,
transactions, locking, logging, shared memory caching, and database
recovery. The Berkeley DB supports C, C++, Java, and Perl APIs. It is
used by many applications, including Python and Perl, so this should
be installed on all systems.

This update fixes the following bug:

* IDs (ID lists) are stored as "duplicate" nested btrees. When such a
list grew big enough enough to require internal pages, the dbverify
utility reported spurious out-of-order errors as follows (note: the
page and entry numbers are context dependent):

db_verify: Page 7: out-of-order key at entry 6

These errors presented because dbverify did not distinguish between
the main database tree and off-page-duplicate trees. With this update,
dbverify now distinguishes between such trees and the spurious errors
no longer occur. (BZ#589879)

All users should upgrade to these updated packages, which resolve this
issue.

Before applying this update, make sure all previously-released errata
relevant to your system have been applied.
