fun with whitespace in profile names

apparmor_parser accepts profile names with leading whitespace, which leads to various funny effects.

    echo 'profile " foo" { }' | apparmor_parser -r

The most interesting effects are:
- you can load multiple profiles with the same name, it doesn't get replaced
- loading a "foo" profile (without whitespace) will replace it (or conflict if you didn't use -r)
- aa-exec -p "foo" and aa-exec -p " foo" both use this profile
- to onload the profile, you have to use "foo" (without whitespace) as profile name

I can probably dig out more funny things from yesterday's IRC log ;-)
