Added a case for bug #4976 when one of the inner tables is empty.
select.result, join.result:
  Reversed the previous change of the erronious fix for bug #4976.
sql_select.cc:
  The previous fix for bug 4976 was reversed as it
  erroniously converted an outer join into an innner join
  when on_expression does not refer to outer tables.
  This is not valid if inner tables return an empty set.
  Setting dependency on outer tables was added for the above cases.
  To fix the crash in the test case of bug #4976  
  a guard was added that blocks running the crashing code for
  nested outer joins.

  The description is not entirerly correct. The issue was follow-up errors
  where the first error is not caught - in which case it's often a system
  error with errcode < 1000 (which are mapped by default to 'HY000'). In this
  case the error state is different from what was assumed in the execution
  loop.

- client side part is simple and may be considered stable
- server side part now just joggles with THD state to save execution
  state and has no additional locking wisdom.
  Lot's of it are to be rewritten.


include/mysql.h:
  Cursor patch to push into the main tree, client library part (considered 
  stable):
  - new statement attribute STMT_ATTR_CURSOR_TYPE
  - MYSQL_STMT::flags to store statement cursor type
  - MYSQL_STMT::server_status to store server status (i. e. if the server
  was able to open a cursor for this query).
include/mysql_com.h:
  Cursor patch to push into the main tree, client library part (considered 
  stable):
  - new COMmand, COM_FETCH, to fetch K rows from read-only cursor.
    By design should support scrollable cursors as well.
  - a few new server statuses:
    SERVER_STATUS_CURSOR_EXISTS is sent by server in reply to COM_EXECUTE,
    when cursor was successfully opened for this query
    SERVER_STATUS_LAST_ROW_SENT is sent along with the last row to prevent one
    more round trip just for finding out that all rows were fetched from 
    this cursor (this is server mem savier also).
  - and finally, all possible values of STMT_ATTR_CURSOR_TYPE, 
    while now we support only CURSORT_TYPE_NO_CURSOR and 
    CURSOR_TYPE_READ_ONLY
libmysql/libmysql.c:
  Cursor patch to push into the main tree, client library part (considered 
  stable):
  - simple additions to mysql_stmt_fetch implementation to read data 
    from an opened cursor: we can read up to iteration count rows per
    one request; read rows are buffered in the same way as rows of
    mysql_stmt_store_result.
  - now send stmt->flags to server to let him now if we wish to have 
    a cursor for this statement.
  - support for setting/getting statement cursor type.
libmysqld/examples/Makefile.am:
  Testing cursors was originally implemented in C++. Now when these tests
  go into client_test, it's time to convert it to C++ as well.

sql/protocol.cc:

  - we can't anymore assert that field_types[field_pos] is sensible:
    if we have COM_EXCUTE(stmt1), COM_EXECUTE(stmt2), COM_FETCH(stmt1)
    field_types[field_pos] will point to fields of stmt2.

sql/sql_parse.cc:
  Server side support for cursors:
  - handle COM_FETCH
  - enforce assumption that whenever we free thd->free_list, 
    we reset it to zero. This way it's much easier to handle free_list
    in prepared statements implementation.
sql/sql_prepare.cc:
  Server side support for cursors:
  - implementation of mysql_stmt_fetch (fetch some rows from open cursor).
  - management of cursors memory is quite tricky now.
  - execute_stmt can't be reused anymore in mysql_stmt_execute and 
    mysql_sql_stmt_execute
sql/sql_repl.cc:
  - cleanup: send_fields flags are now named.
sql/sql_select.cc:
  Server side support for cursors:
  - implementation of Cursor::open, Cursor::fetch (buggy when it comes to
    non-equi joins), cursor cleanups.
  - -4 -3 -0 constants indicating return value of sub_select and end_send are
    to be renamed to something more readable:
    it turned out to be not so simple, so it should come with the other patch.
sql/sql_select.h:
  Server side support for cursors:
  - declaration of Cursor class.
  - JOIN::fetch_limit contains runtime value of rows fetched via cursor.
sql/sql_show.cc:
  - cleanup: send_fields flags are now named.
sql/sql_table.cc:
  - cleanup: send_fields flags are now named.
sql/sql_union.cc:

at least partially. It doesn't crash or give packets out of order

for the moment this will have to do. (It is a rather obscure feature... :)

client/mysqlbinlog.cc:
  - In mysqlbinlog, we should not reset the Format event when we see Rotate. If a binlog started with a Format event, it is not going to switch later to 4.0 format.
  I had already did the same fix in Rotate_log_event::exec_event() in replication.
  - Fix for a merge bug.
sql/log_event.cc:
  An event with an uninited catalog (read from a 4.x server) is not the same as an event with a NULL catalog
  (5.0 server which did not specify catalog), the difference is that they are not in the same format;
  so I introduce a way to know if the catalog has been inited or not. This fixes a rpl_trunc_binlog failure
  I had.
  When we leave Load_log_event::exec_event(), we must reset thd->catalog to 0, like we already do
  in Query_log_event::exec_event(). This fixes a Valgrind error which popped in rpl_charset (which may
  be what caused autobuild to crash yesterday).
  And a fix for event's parsing (the position was always computed right because start_dup==end is always true
  and will until we add new string members to Query_log_event.
sql/log_event.h:
  catalog_len changed from uint to int to allow -1, which means "not inited"
  (I preferred to do it like this rather than create a new bool var Query_log_event::catalog_inited
  like we have in Query_log_event::sql_mode_inited; that's because catalog will not use the whole range of int,
  so it's allowed to pick -1 as a special value and have only one var.
