- The io cache flag seek_not_done was not set properly in the reinit_
io_chache function call and this led my_seek to be called despite an
invalid file handle.
- Added a test in reinit_io_cache to ensure we have a valid file handle
before setting seek_not_done flag.

Bug#21424 mysqldump failing to export/import views.                                                                                                                                                                  

Dumps are created for the tables in each specified database then for the views in each specified database. This bug occurs when any database's views depend on the mysql database's table data while being restored. 
Added command line option --flush-privileges to the mysqldump utility which causes a FLUSH PRIVILIGES statement to be written to the dump after the mysql database.

The column's NOT NULL flag doesn't affect what we should print.  Remove the
wrong logic that does check it.

Also, verify that this and the previous two tests print the same data as 
other output formats.
