(ASCII space).  For Bug#16857.


sql/field_conv.cc:
  Bug#16857:  Do not expand BINARY fields as if they are strings (which 
  presumably /should/ be filled with spaces).  Instead, fill BINARY fields
  with 0x00 bytes.

                 time per connection
  Removed const_string() method from Item_string (it was only used in one
  place, in a bad way). Defer possible SP variable, and access data directly
  instead, in date_format item.


mysql-test/r/sp.result:
  Updated results for new test (BUG#17476).
mysql-test/t/sp.test:
  New test case (BUG#17476)
sql/item.h:
  Removed const_string() from Item_string.
  It was only used in one place, and we can just use str_value in Item directly.
sql/item_timefunc.cc:
  Must defer a (possible) local SP variable to use max_length and str_value
  in Item_func_date_format::fix_length_and_dec(), and refer to str_value
  directly without the const_string() method (now removed); the cast didn't
  work in all cases anyway.

 - Change to use non blocking read to empty channel in case of too large sd number
 - Don't check for too large socket number on Windows.


sql/net_serv.cc:
  Windows does not need protection from sd >= FD_SETSIZE, it uses an array to store the sd's it should read from.
  Change the handler for when "net_data_is_ready" returns -1 to perform nonblocking read to empty the net.
  Only include that handler if HAVE_POLL is not defined  and not windows

  Allocating/freeing memory for the db member of THD
  is wholy managed by slave thread.

  Add a "--comment=<string>" option (backport from 5.1).
  Its sole purpose is to get logged, so that test evaluation gets easier.
