The function str_to_date has a field to say whether it's invoked constant 
arguments. But this member was not initialized, causing the function to
think that it could use a cache of the format type when said cache was in 
fact not initialized.
Fixed by initializing the field to false.

  Post-merge fix.

The Item_func_rollup_const class is used for wrapping constants to avoid
wrong result for ROLLUP queries with DISTINCT and a constant in the select
list. This class is also used to wrap up a NULL constant but its null_value
wasn't set accordingly. This led to a server crash.

Now the null_value of an object of the Item_func_rollup_const class is set
by its fix_length_and_dec member function.

mysqldump adds the "-- Dump completed on YYYY-MM-DD hh:mm:ss" string
to the end of output if the --comments switch is on.
The only way to suppress this line is to use --skip-comments/--compact
switch.

New switch has been added to the mysqldump client command line:
--dump-date.

For the compatibility with previous releases, by default the --dump-date
is on.
The --dump-date switch forces mysqldump to add date to the
"-- Dump completed on ..." string at the end of output.
The --skip-dump-date switch supresses the output of date string
and uses short form of that commentary: "-- Dump completed".
--skip-comments or --compact switches disable the whole commentary
as usual.

  Corrected test case for the bug#29908.

into  moonbone.local:/work/27990-bug-5.0-opt-mysql

The change_to_use_tmp_fields function leaves the orig_table member of an
expression's tmp table field filled for the new Item_field being created.
Later orig_table is used by the Field::make_field function to provide some
info about original table and field name to a user. This is ok for a field
but for an expression it should be empty.

The change_to_use_tmp_fields function now resets orig_table member of
an expression's tmp table field to prevent providing a wrong info to a user.
The Field::make_field function now resets the table_name and the org_col_name
variables when the orig_table is set to 0.

The NAME_CONST function is required to work correctly with constants only.
When executed with functions that return types other than those returned by
Item::field_type (string, int, decimal, or real), the result gets cast to
one of those types. This cannot happen for constants.
Fixed by only allowing constants as arguments to NAME_CONST.
