Optimization of queries with DETERMINISTIC functions in the
WHERE clause was not effective: sequential scan was always
used.
Now a SF with the DETERMINISTIC flags is treated as constant
when it's arguments are constants (or a SF doesn't has arguments).


sql/item_func.h:
  Fixed bug #29338.
  The Item_func_sp::used_tables has been removed
  (virtual Item_func::used_tables function is enough).
  The virtual Item_func_sp::update_used_tables function
  has been added.
sql/item_func.cc:
  Fixed bug #29338.
  The Item_func_sp::update_used_tables and the
  Item_func_sp::fix_field functions have been modified
  to take into account the DETERMINISTIC flag of SF definition.

Time values were compared by the BETWEEN function as strings. This led to a
wrong result in cases when some of arguments are less than 100 hours and other
are greater.

Now if all 3 arguments of the BETWEEN function are of the TIME type then
they are compared as integers.

A bug in the restore_prev_nj_state function allowed interleaving 
inner tables of outer join operations with outer tables. With the
current implementation of the nested loops algorithm it could lead
to wrong result sets for queries with nested outer joins.
Another bug in this procedure effectively blocked evaluation of some
valid execution plans for queries with nested outer joins.

Time values were compared as strings. This led to a wrong comparison
result when comparing values one of which is under 100 hours and another is
over 100 hours.

Now when the Arg_comparator::set_cmp_func function sees that both items to

Arg_comparator::compare_e_int or the Arg_comparator::compare_int_unsigned
functions.

By default MyISAM overwrites .MYD and .MYI files no 
DATA DIRECTORY option is used. This can lead to two tables
using the same .MYD and .MYI files (that can't be dropped).

To prevent CREATE TABLE from overwriting a file a new option
is introduced : keep_files_on_create
When this is on the CREATE TABLE throws an error if either
the .MYD or .MYI exists for a MyISAM table.
The option is off by default (resulting in compatible behavior).

The Ctrl-C handler in mysql closes the console while ReadConsole()
waits for console input.
But the main thread was detecting that ReadConsole() haven't read 
anything and was processing as if there're data in the buffer.
Fixed to handle correctly this error condition.
No test case added as the test relies on Ctrl-C sent to the client
from its console.

with the space character.

When the my_strnncollsp_simple function compares two strings and one is a prefix
of another then this function compares characters in the rest of longer key
with the space character to find whether the longer key is greater or less.
But the sort order of the collation isn't used in this comparison. This may
lead to a wrong comparison result, wrongly created index or wrong order of the
result set of a query with the ORDER BY clause.

Now the my_strnncollsp_simple function uses collation sort order to compare
the characters in the rest of longer key with the space character.
