Fix for BUG#20438: CREATE statements for views, stored routines and triggers

Browse Source 
can be not replicable.

Now CREATE statements for writing in the binlog are created as follows:
  - the beginning of the statement is re-created;
  - the rest of the statement is copied from the original query.

The problem appears when there is a version-specific comment (produced by
mysqldump), started in the re-created part of the statement and closed in the
copied part -- there is closing comment-parenthesis, but there is no opening
one.

The proper fix could be to re-create original statement, but we can not
implement it in 5.0. So, for 5.0 the fix is just to cut closing
comment-parenthesis. This technique is also used for SHOW CREATE PROCEDURE
statement (so we are able to reuse existing code).
