[RFC] Rename *_var_run_t to *_runtime_t

[Chris PeBenito <pebenito@xxxxxxxx>]

/var/run has moved to /run on most systems and it's use has increased 
beyond pid files and sockets. Because of this, new types used in /run 
have for some time followed the convention *_runtime_t. This change 
would rename all *_var_run_t types to *_runtime_t.

Since this adds many aliases to the policy, the patch set also drops all 
old backwards-compatibility aliases.

Any objections to this?
