This patch changes sepolgen so that the generated te files are left in 
the current directory when generating policy modules (with -M). This 
matches the behavior of the old audit2allow and allows review of the te 
file before inserting the module.

This patch also brings up the question of API stability for the sepolgen 
library (as it makes a minor change to the API). I suggest that it 
remain unstable for at least 1 release (i.e., the API can change in 
arbitrary ways). That should give sufficient time for it to stabilize 
and, hopefully, become general enough. Thoughts?
