Remove evolution and evolution alarm dbus chat from common user template
since callers of the evolution role are now allowed to dbus chat to
evolution and evolution alarm.
Common users need to be able to dbus chat with policykit and consolekit

Replaced calls to interfaces allowing access to all files except
auth_file_type files with calls to interfaces allowing access to
non_auth_file_type files.

Note, extra privileges may need to be granted to the samhain domain
if its default configuration file(/etc/samhainrc) is changed.
The samhain program could be used in the following way:
(In secadm_r role)
1. Initialize filesystem signature database:
newrole -l s15:c0.c1023 -p -- -c "samhain -t init"
(Note, the current secadm console will be blocked until
the database is completed)
2. Start samhain deamon to check filesystem integrity
newrole -l s15:c0.c1023 -p -- -c "samhain -t check -D"
3. Update filesystem signature database:
newrole -l s15:c0.c1023 -p -- -c "samhain -t update"
(In sysadm_r role)
1. Start samhain in daemon mode:
run_init /etc/init.d/samhain start
2. Stop samhain daemon:
run_init /etc/init.d/samhain stop
3. Check samhain daemon status:
run_init /etc/init.d/samhain status
4. Read/write samhain log files:
newrole -l s15:c0.c1023 -p -- -c "cat /var/log/samhain_log"
5. Remove samhain database files
newrole -l s15:c0.c1023 -p -- -c "rm /var/lib/samhain/samhain_file"
Note:
1. Stop samhain daemon before updating signature database.
2. Don't try to start samhain daemon twice.
3. Need to toggle SELinux into the Permissive mode in order to remove
the samhain_log files from /var/log/.

This is based on Fedoras' miscfiles_cert_type implementation.
The idea was that openvpn needs to be able read home certificates (home_cert_t) which is not implemented in refpolicy yet, as well as generic cert_t certificates.
Note that openvpn is allowed to read all cert_types, as i know that it needs access to both generic cert_t as well as (future) home_cert_t. Dwalsh noted that other domains may need this as well but because i do not know exactly which domains i will not changes any other domains call to generic cert type interfaces.

All login users can list cgroup.
Common users can read and write cgroup files (access governed by dac)

Fix various interfaces to use permission sets for compatiblity with open permission.
Also use other permission sets where possible just because applicable permissions sets are available and the use of permission sets is encourage generally for compatibility.
The use of exec_file_perms permission set may be not be a good idea though since it may be a bit too coarse.

Add policy for the new TUN driver access controls which allow policy to
control which domains have the ability to create and attach to TUN/TAP
devices. The policy rules for creating and attaching to a device are as
shown below:
# create a new device
allow domain_t self:tun_socket { create };
# attach to a persistent device (created by tunlbl_t)
allow domain_t tunlbl_t:tun_socket { relabelfrom };
allow domain_t self:tun_socket { relabelto };

The X policy for users is currently split between
userdom_xwindows_client_template() and xserver_role(). Deprecate
the former and put the rules into the latter.
For preserving restricted X roles (xguest), divide the rules
into xserver_restricted_role() and xserver_role().
