bftpd: Update to 5.6

Jesse Smith <jessefrgsmith@yahoo.ca> -> 5.6
	- When Bftpd is run with the -n flag (no configuration file)
          default ratio settings prevented files from downloading.
          Samuel Hsu has patched Bftpd to assume no ratio ("") is
          treated the same as "none" or no restrictions.
	- Fixed potential overflow in buffer for directory listing.
	- Used calloc() and single strlen() call to avoid having
	  a string without a NULL terminator mystring library.
