Fixes and test cases for Bug#8880 "Commands out of sync error with cursors"
and Bug#9159 "Server crash during mysql_stmt_close".
The patch adds support for single-row result sets in cursors.
libmysql/libmysql.c:
If we wanted a cursor, and the server wasn't able to create one,
buffer all rows on client. Currently this is possible only for
single row result sets and some SHOW commands.
sql/sql_prepare.cc:
Properly free resources if there was a request to open a cursor which
wasn't fullfilled.
Give error on attempt to open a cursor for a statement not returning
a result set.
sql/sql_select.h:
Initialize Item_arena of Cursor object. A case when a cursor object
is created but not used is possible with single-row result sets.
tests/mysql_client_test.c:
Test cases for Bug#8880 and Bug#9159
