I want to change the default of libsemanage to not look for home 
directories in getpwent.  This patch allows you to set the flag 
usepasswd=false in the semanage.conf file. and genhomedircon will only 
setup the labeling of /home, /export/home and any confined users homedirs.

If this patch is not acceptable because libsemanage is being rewritten, 
I would like the functionality to be added to the new libsemanage.
