SETools source policy support will be dropped

[Chris PeBenito <pebenito@xxxxxxxx>]

I've been doing some reworking of SETools' policy representation 
library.  I'm planning to remove SETools' support for loading source 
policies (policy.conf).

There are reasons to do this; first, the SETools code includes a portion 
of the compiler toolchain to do the compiling in memory.  Removing that 
will reduce the maintenance burden for keeping that code in sync and 
also reduce the SETools code size.  It will also ensure that there are 
no errors introduced by SETools' compilation of the policy sources. 
Additionally, it should break the SETools static linking requirement, so 
SETools doesn't need to be recompiled every time a new libsepol is released.

I don't think this will impact many, but let me know if this is a severe 
problem.
