New item created in find_field_in_table() to fix view's item, was created 
without taking into account original item's alias. This patch checks if alias 
is set to the original item and if so sets it to newly created item.

We want to have the defacto standard syntax for labels ("L:" instead of "label L;"),
and fix some known bugs, before we enable this again.
The code is left intact (#ifdef'ed SP_GOTO) and the test cases are kept in
sp-goto.test, for the future...

    Add a test case for Bug#11656 "Server crash with mysql_stmt_fetch 
    (cursors)", the bug itself is no longer present.

CURSOR_TYPE_READ_ONLY date/datetime filter server crash".
The fix adds support for Item_change_list in cursors (proper rollback
of the modified item tree).

  Fixed the results of a test for group_concat.
  After the fix foor bug #11639 the results became
  correct.
olap.result, olap.test:
  Added a test case for bug #11639.
sql_select.cc:
  Fixed bug #11639: a wrong result set when using a view
  instead of the underlying table in a rollup query 
  executed through filesort.
  The old code did not take into account that we always
  use an Item_ref object when referring to a view column.
item.h:
  Fixed bug #11639.
  Now if two Item_ref items ref1 and ref2 refer to the same field
  then ref1->eq(ref2) returns 1.

  Bug#11657 Creation of secondary index fails:

  If TINYBLOB key part length is 255, it is equal
  to field length. For BLOB, unlike for CHAR/VARCHAR,
  we should keep a non-zero key part length, otherwise
  "BLOB/TEXT column used in key specification without a key length"
  error is produced afterwards.
