Update the apache2-common abstraction so that the parent apache process
can kill worker processes inside of hats, as well as handle the updated
mod_apparmor behavior that invokes aa_change_hatv() and then checks
which hat it ended up in via aa_getconn() (which reads from
{PROC}/@{pid}/attr/current).

This patch adds the kernelvars tunable to the global set that is usually
included by default in apparmor policies. It then converts the rules
that are intended to match /proc/pid to use this tunable.

This patch finishes the conversion from /proc to the @{PROC}
tunable within profiles and abstractions. It also adjusts some of
the /proc/*/something usages to @{PROC}/[0-9]*/something to restrict
things to just the /proc/pid directories. (A followup patch will
convert these to use @{pid} from the kernelvars tunable.)

abstractions/apache2-common. Additionally, add read permissions
for /**/.htaccess and /dev/urandom to apache2-common.
The patch is based on a profile abstraction from darix. I made some
things more strict (compared to darix' profile), and OTOH added some
things that are needed on my servers.
*** BACKWARDS-INCOMPATIBLE CHANGES ***
^HANDLING_UNTRUSTED_INPUT
- don't allow /.htaccess (.htaccess files in subdirectories are still allowed)
- don't allow *.htaccess files (the old /**.htaccess rule was too generous)
