[apparmor] [Patch 0/3] v2 of more apparmor.d.pod cleanups

[John Johansen]

I believe this series addresses all the issues that Christian raised
when commenting on the last set of patches (https://lists.ubuntu.com/archives/apparmor/2015-March/007509.html).

- Specifically the rules are grouped and cleaned up
- RESOURCE RULE is removed
- ALIAS RULE is added to the rules list
- rule commas are cleaned up and consolidated to one place B<COMMA RULES>
- a B<PROFILE FILE> grouping is added, which allows separating the
  preamble and the profiles, and allows showing that multiple profiles
  are allowed
- use of profile keyword is added
- optional attachment specification is added
- profile flags definition is updated and more flags are added
- subprofiles now refer to the same rule block as profiles
- hats and hat keyword are added
