Browse Source 
This patch forces the use of 'DROP VIEW' to destroy views.

It also changes the syntax of DROP VIEW to
DROP VIEW v1, v2, ...
to match the syntax of DROP TABLE.

Some error messages were changed so this patch also includes changes to the
appropriate expected/*.out files.

Doc changes for 'DROP TABLE" and 'DROP VIEW' are included.
