Description:
falcon_index_chill_threshold and falcon_record_chill_threshold accept a value in megabytes. This is:

* non-standard with respect to the rest of the server options, which accept values in bytes
* prevents from setting the variables to lower than 1mb, which prevents testing of the chill/thaw mechanism;
* Prevents the user from using the KB, MB and GB modifiers provided by server

How to repeat:
SHOW VARIABLES LIKE '%falcon%threshold%';

Suggested fix:
* convert those options to use values in bytes
* make sure the KB, MB, GB modifiers work

      bug#36825 - falcon_index_chill_threshold and falcon_record_chill_threshold have values in MB
            
      falcon_index_chill_threshold and falcon_record_chill_threshold accept a value in megabytes. 
      This is non-standard with respect to the rest of the server options, prevents from setting 
      the variables to lower than 1mb, which prevents testing of the chill/thaw mechanism and 
      prevents the user from using the KB, MB and GB modifiers provided by server.
                  
      falcon_index_chill_threshold and falcon_record_chill_threshold are now changed to accept a value 
      in bytes.
            
      The tests falcon_options and falcon_options2 are also changed to work accordingly.

A note has been added to the 6.0.6 changelog: 

The falcon_index_chill_threshold and falcon_record_chill_threshold options have been modified so that the specification for the size can be specified in bytes, and support the KB, MB, and GB modifiers.
