Release 4.3: DB_ENV->set_verbose

The 4.3 release removes support for the DB_ENV->set_verbose method flag DB_VERB_CHKPOINT. Application writers should simply remove any use of this flag from their applications.

The 4.3 release redirects output configured by the DB_ENV->set_verbose method from the error output channels (see the DB_ENV->set_errfile and DB_ENV->set_errcall methods for more information) to the new DB_ENV->set_msgcall and DB_ENV->set_msgfile message output channels. This change means the error output channels are now only used for errors, and not for debugging and performance tuning messages as well as errors. Application writers using DB_ENV->set_verbose should confirm that output is handled appropriately.
