Item_func_group_concat::fix_fields() set maybe_null flag to 0, and set it to
1 only if some of it's arguments may be null. When used in subquery in tmp 
table created field which can't be null. When no data retireved result field
have to be set to null and error mentioned in bug report occurs. Also this 
bug can occur if selecting from not null field in empty table.

Function group_concat now marked maybe_null from the very beginning not only
if some of it's argument may be null.

  Fix bug #12410 : InnoDB was too permissive with LOCK TABLE ... READ LOCAL, and alowed new inserts to the table; we now make READ LOCAL equivalent to READ for InnoDB; note that this will cause slightly more locking in mysqldump, but makes the InnoDB table dumps consistent with MyISAM table dumps; note that the real code change patch was accidentally pushed with my another patch 5 minutes ago

  Fix bug #12852 : do not increment the open handle count to a table if the table does not have an .ibd file and InnoDB decides to return an error from the ::open() function; then the table can be dropped even if the user has tried to open it

Item::tmp_table_field_from_field_type() and create_tmp_field_from_item()
was converting string field to blob depending on byte-wise length instead of
character length, which results in converting valid varchar string with
length == 86 to longtext.

Made that functions above take into account max width of character when
converting string fields to blobs.
