The number of type attributes included in the binary policy is becomming a

This patch set more aggressives removes attributes and gives the options to
expand and remove all auto-generated attributes and all attributes with fewer
than a given amount of attributes assigned.
Comparison of the number of attributes remaining in the binary policy

Org - Number of attributes in the CIL policy
Old - Results without this patch set
Max - Remove the maximum number of attributes: "-G -X 9999"
Min - Remove the minimum number of attributes: "-X 0"
Def - The new defaults for CIL
Gen - Just removing auto-generated attributes: "-G"
U5 - Remove attributes with less than five members: "-X 5"
v2:
- Use "--expand-generated" and "--expand-size" as options for consistency.
- Fixed bug in cil_post.c:__cil_post_db_attr_helper() where
cil_typeattribute_used() would not be called if the attribute type bitmap was
already created.
