Bug#36570: Parse error of CREATE PROCEDURE stmt with comments on \

	slave

The stored-routine code took the contents of the (lowest) parser
and copied it directly to the binlog, which causes problems if there
is a special case of interpretation at the parser level -- which 
there is, in the "/*!VER */" comments.  The trailing "*/" caused
errors on the slave, naturally.

Now, since by that point we have /properly/ created parse-tree (as 
the rest of the server should do!) for the stored-routine CREATE, we
can construct a perfect statement from that information, instead of
writing uncertain information from an unknown parser state.  
Fortunately, there's already a function nearby that does exactly 
that.
---
Update for Bug#36570.  Qualify routine names with db name when
writing to the binlog ONLY if the source text is qualified.


mysql-test/r/binlog_innodb.result:
  Offsets changed due to quoting.
  ---
  New offset to account for db-qualified names.
mysql-test/r/ctype_cp932_binlog.result:
  Offsets changed due to quoting.
  ---
  Qualify routine names with DB.  Offsets change also.
mysql-test/r/mysqlbinlog.result:
  Case changed in result due to interpretation of data instead of 
  literal recitation.
  ---
  Qualify procedure name with db.
mysql-test/r/rpl_sp.result:
  Offsets changed due to quoting.  Added tests.
  ---
  Qualify routine names with DB if qualified in query.  Offsets change also.
mysql-test/t/rpl_sp.test:
  Add version-limiting quotes to exercise bug#36570.  Test that 
  backtick-quoted identifiers and labels work also.
  ---
  Use different db to show qualification works.  Qualify routine names
  with DB if qualified in query.
sql/sp.cc:
  In create_string, we may not have a sp_name parameter yet, so
  instead pass the char* and length of the only member we'd get out
  of it.
  
  Having done that, we can use the same function to write the 
  CREATE (FUNC|TRIG|PROC) statement to the binlog as we always used
  to display the statement to the user.
  ---
  Make the db name part of the CREATE string if it is specified.
  
  Specify it in part of writing to the binlog when creating a new
  routine.
sql/sp_head.cc:
  Set the sp_head m_explicit_name member as the sp_name member is set.  
  We can not peek at this later, as the sp_name is gone by then.
sql/sp_head.h:
  Add a member to track whether the name is qualified with the 
  database.
