Fixed the usage of spatial data (and Point in specific) with 
 non-spatial indexes.
 Several problems :
   - The length of the Point class was not updated to include the 
     spatial reference system identifier. Fixed by increasing with 4 
     bytes.
   - The storage length of the spatial columns was not accounting for
     the length that is prepended to it. Fixed by treating the 
     spatial data columns as blobs (and thus increasing the storage
     length)
   - When creating the key image for comparison in index read wrong
     key image was created (the one needed for and r-tree search,
     not the one for b-tree/other search). Fixed by treating the
     spatial data columns as blobs (and creating the correct kind of
     image based on the index type).

Even though it returns NULL, the MAKETIME function did not have this property set,
causing a failed assertion (designed to catch exactly this).
Fixed by setting the nullability property of MAKETIME().

As the result of DOUBLE claculations can be bigger
than DBL_MAX constant we use in code, we shouldn't use this constatn
as a biggest possible value.
Particularly the rtree_pick_key function set 'min_area= DBL_MAX' relying
that any rtree_area_increase result will be less so we return valid
key. Though in rtree_area_increase function we calculate the area
of the rectangle, so the result can be 'inf' if the rectangle is
huge enough, which is bigger than DBL_MAX.

Code of the rtree_pick_key modified so we always return a valid key.

added check for hidden I_S tables for 'show columns|keys' commands

were accidentally removed during a previous rototill of this
code.  Fixes bug#27692.
  
While it can be argued we should strive to provide a 'secure by
default' installation, this happens to be the setup currently
documented in the manual as the default, so defer changes that
improve security out of the box to a co-ordinated effort later
on.
  
For now, make a note about the test databases and anonymous user
in mysql_install_db and recommend that mysql_secure_installation
be ran for users wishing to remove these defaults.

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.

end-of-line check missed in Gis_read_stream::get_next_word,
what can lead to crashes (expecially with NULL strings).

End-of-line check added

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.
