added correct handling of NULL values for lookup fields

When doing indexed search the server constructs a key image for 
faster comparison to the stored keys. While doing that it must not
perform (and stop if they fail) the additional date checks that can 
be turned on by the SQL mode because there already may be values in 
the table that don't comply with the error checks.
Fixed by ignoring these SQL mode bits while making the key image.

Since, as of MySQL 5.0.15, CHAR() arguments larger than 255 are converted into multiple result bytes, a single CHAR() argument can now take up to 4 bytes. This patch fixes Item_func_char::fix_length_and_dec() to take this into account.
  
This patch also fixes a regression introduced by the patch for bug21513. As now we do not always have the 'name' member of Item set for Item_hex_string and Item_bin_string, an own print() method has been added to Item_hex_string so that it could correctly be printed by Item_func::print_args().

The uncacheable flag should be set at fix_fields() stage.
Fixed by moving the flag setting to match the one in 5.1

 No warning was generated when a TIMESTAMP with a non-zero time part
 was converted to a DATE value. This caused index lookup to assume
 that this is a valid conversion and was returning rows that match 
 a comparison between a TIMESTAMP value and a DATE keypart.
 Fixed by generating a warning on such a truncation.

The BIG_TABLES define wasn't enabled on Windows.
#define added

post-merge fixes: format string was changed 5.0 -> 5.1, resulting in longer output
