Bug# 20221- Dumping of multiple databases containing view(s) yields maleformed dumps.

client/mysqldump.c:
  When dumping more than one database, make sure that the proper database is selected before restoring that database's views.
  Replaced hard-coded database name length with appropiate token.
mysql-test/r/mysqldump.result:
  Added new result and corrected results for existing test cases.
mysql-test/t/mysqldump.test:
  Added new case for dumping and restoring multiple databases each containing a view.
