Subject: A fix and a test case for Bug#6513 "Test Suite: Values inserted by
 using cursor is interpreted latin1 character and Bug#9819 "Cursors: Mysql
 Server Crash while fetching from table with 5 million records." A fix for a
 possible memory leak when fetching into an SP cursor in a long loop. The
 patch uses a common implementation of cursors in the binary protocol and in
 stored procedures and implements materialized cursors. For implementation
 details, see comments in sql_cursor.cc
