Fixes for #3371, #3372, #3374, #3375, #3376

libmysql/libmysql.c:
  code to fix #3772
  counting of field->max_length moved to mysql_store_stmt_result so
  it will work in libmysqld also
libmysqld/lib_sql.cc:
  to fix #3771 and #3775
  stmt->affected_rows specifying added
  code getting default values changed so it will add terminating /0 to
  values
sql/sql_parse.cc:
  to fix #3773
  silly mistake here :\
sql/sql_prepare.cc:
  to fix #3774 and #3776
  special function for datetime values in embedded server added
  unsigned flag now specified for values in embedded server
tests/client_test.c:
  this test fails if privilege-checking pars are disabled
  (it's the default for libmysqld)
