[pkg-apparmor] Bug#807369: apparmor: Apparmor "deny network" not working in Jessie

[intrigeri]

Control: retitle -1 Document which AppArmor features are not support in Debian

Hi,

apparently users are confused by upstream documentation (that assumes
all out-of-tree kernel patches are applied), or by the documentation
we ship (that also advertises features we can't support with a kernel
as close to mainline as the Debian one) — not sure which of those, but
regardless, the best we can do is probably:

 * patch apparmor.d(5) to add an introduction that lists some of the
   features we can't provide on Debian, and makes it clear that the
   list may be incomplete;

 * add something in README.Debian about it.

If someone feels strongly about how making the userspace tools behave
differently, patches are welcome (but a mere warning would just get us
back to Wheezy-area, that thankfully we've escaped, so IMO the warning
should be non-scary, point to some understandable and up-to-date
documentation, and not be spammed repeatedly to the user; UX matters).

I personally would be happy enough would a purely
documentation-based solution.

Cheers,
