This was working but the cause probably comes from freeing Xop object to
handle memory leaks reported by Valgrind.
Also add a test case on XML multiple tables.

- All the functions querying table options could return information from the wrong
table when several CONNECT tables were used in the same query (for instance joined
together) This was because they belonged to the catalog class that is shared between
all tables in the same query. They have been moved from the catalog class to the
TABDEF/RELDEF class that is attached to each table. This was a major potential bug.

archive table which is using an auto increment column, the
server hangs. In order to recover the mysqld process, it
has to be terminated abnormally using SIGKILL. The problem
is observed in mysql-5.5.
Bug #18065452 "PREPARING" STATE HOGS CPU WITH ARCHIVE
+ SUBQUERY
Analysis: This happens because the server is trapped inside
an infinite loop in the function,
"subselect_indexsubquery_engine::exec()". This function
resolves the correlated suquery by doing an index lookup
for the appropriate engine. In case of archive engine,
after reaching the end of records, "table->status" is not
set to STATUS_NOT_FOUND. As a result the loop is not
terminated.
Fix: The "table->status" is set to STATUS_NOT_FOUND when
the end of records is reached.

THE PERFORMANCE UNDER HEAVY INSERT
Problem:
There are three memset call to allocate memory for system fields
in each insert.
Solution:
Instead of calling it in 3 times, we can combine it into
one memset call. It will reduce the CPU usage under heavy insert.
