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().
The latest revision of the labeled policy patches which enable both labeled
and unlabeled policy support for NetLabel. This revision takes into account
Chris' feedback from the first version and reduces the number of interface
calls in each domain down to two at present: one for unlabeled access, one for
NetLabel access. The older, transport layer specific interfaces, are still
present for use by third-party modules but are not used in the default policy
modules.
trunk: Use netmsg initial SID for MLS-only Netlabel packets, from Paul Moore.
This patch changes the policy to use the netmsg initial SID as the "base"
SID/context for NetLabel packets which only have MLS security attributes.
Currently we use the unlabeled initial SID which makes it very difficult to
distinquish between actual unlabeled packets and those packets which have MLS
security attributes.
