2.16.4 Stuff:

- Fix for a recently reported security issue that has ID
 CVE-2006-6105.  This fixes a problem where a user can
 enter strings like "%08x" into the gdmchooser "Add"j
 host button and print out memory.  (Brian Cameron)

- Fix for TryExec check in gdmsession to make sure that any
 arguments are not passed to g_find_program_in_path since
 this causes the function to say it is not executable.
 (Brian Cameron)
