The client program 'mysqlbinlog' crashed when trying to print a User_var_log_event holding
a floating-point value since the format specifier for my_b_printf() does not support
floating-point format specifiers.

This patch prints the floating-point number to an internal buffer, and then writes
that buffer to the output instead.

- Reorganize collect a little to make it easier to apply optimizations
  and settings to collected test cases.
- Add suite/rpl/combination file
- Rename include/set_binlog_format_x.inc to .sql since thay are run by "mysql"
