* Remove libdb4.8-dev dependency in libaprutil1-dev. This allows packages build-depending on apr-util1 to use a different version of db than apr-util. * With the libdb build-dependency decoupled from subversion, we can now build-depend on libdb-dev instead of libdb4.8-dev. Users of APU_WANT_DB in apu_want.h would have to depend on libdb-dev explicitly, but there are none outside of apr-util itself. Closes: #621366 * Add configure support for libdb 5.1. * Bump standards version to 3.9.2 (no changes) * Fix some lintian warnings about the short descriptions.
