The number of type attributes included in the binary policy is becomming a performance issue in some cases.

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
     mls   normal  android
org  310     286     255
old  268     251     130
max   71      20      17
min  226     173     119
def  223     170      80
gen  220     170      46
u5   164     112      59

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.
