8bit escape characters, termination and enclosed characters
were silently ignored by SELECT INTO query, but LOAD DATA INFILE
algorithm is 8bit-clean, so data was corrupted during 
encoding.


sql/sql_class.cc:
  Fixed bug #32533.
  SELECT INTO OUTFILE encoding was not 8bit clear, it
  has been fixed for a symmetry with the LOAD DATA INFILE
  decoding algorithm.
mysql-test/t/outfile_loaddata.test:

mysql-test/r/outfile_loaddata.result:
  Added test case for bug #32533.
