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.

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.

When calculating the result length of an integer DIV function 
the number of decimals was used without checking the result type
first. Thus an uninitialized number of decimals was used for some 
types. This caused an excessive amount of memory to be allocated 
for the field's buffer and crashed the server.

 
Fixed by using the number of decimals only for data types that 
can have decimals and thus have valid decimals number.

The optimizer takes different execution paths during EXPLAIN than SELECT,
this fix relates only to EXPLAIN, hence no behavior changes.
The test of sort keys for ORDER BY was prohibited from considering keys
that were mentioned in IGNORE KEYS FOR ORDER BY. This led to two 
inconsistencies: One was that IGNORE INDEX FOR GROUP BY and 
IGNORE INDEX FOR ORDER BY gave apparently different EXPLAINs; the latter 
erroneously claimed to do filesort. The second inconsistency 
is that the test of sort keys is called twice, finding a sort key the first
time but not the second time, leading to the mentioned filesort.

Fixed by making the test of sort keys consider all enabled 
keys on the table. This test rejects keys that are not covering, and for 
covering keys the hint should be ignored anyway.

When expanding a * in a USING/NATURAL join the check for table access
for both tables in the join was done using the grant information of the
first one.
Fixed by getting the grant information for the current table while 
iterating through the columns of the join.

  Post-commit fix.
