Changes to the backup API: (1) if a negative number is passed as the second argument to backup_step(), this is interpreted as "copy all remaining pages" and (2) if backup_finish() is called after backup_step() fails with a BUSY or LOCKED error, then this error is also returned by backup_finish() (same handling as for other errors encountered by backup_step()).

Correction to check-ins (6246) and (6247): The backup object might not
...
hold a valid destination connection pointer. Also, do not reset the
page cache when establishing a read-lock while there is a persistent
or truncated journal, only if there is a journal that really needs to
rollback. Otherwise backups always reset whenever the source database
file is read. (CVS 6248)
