sepolicy: add wigig and FST rules

This is a cumulative patch which adds rules needed
for wigig and FST, including cleanup of rules that
are no longer needed, and adjustments for new sepolicy
restrictions.

Based on these changes:
1) sepolicy: Add policies for FST manager service

Add SE policies for FST Manager daemon required for
fast-session-transfer feature.

Change-Id: I3750d298c33e9f70e51545a678502b6d7dd0b0e6

2) sepolicy: allow fstman write permissions to wifi directory

FST Manager needs write permissions to wifi directory for supporting
whitelist of rate upgrate interface (wlan1)

3) sepolicy: support wigig services

For managing the wigig network, define wigig services as
system service and allow access to wpa_wigig0 control socket.

wigig supplicant creates sockets under /data/misc/wifi/wigig_sockets.

4) sepolicy: Update policies for FST

Recent android changes removed permission for
systemserver and netd to read system properties.

Added such support as it is needed for fst feature

5) sepolicy: support wigig services and fast session transfer

Add rules for allowing wigig framework and FST to work.
Includes:
- communication between wigig framework and wigig HAL service
- permissions for wigig HAL service
- file/socket permissions for fstman daemon
- permissions for WIFI framework to operate FST.

Change-Id: Ibf0970aa0f06fac1dab4d8a2b31a9f0fc4ab3a6e

6) sepolicy: support FST in SoftAP mode

Add rules needed for supporting FST in SoftAP mode:
- Extend the wifi_vendor_hostapd_socket file definition to include
  the hostapd global socket.
- Allow hostapd to send messages back to fstman event socket
- Allow fstman to communicate with hostapd global socket.

7) sepolicy: add rules for wigig network performance tuner(npt)

Add rules needed to support the wigig network performance tuner.
The npt is a standalone service which provides the ability to
tune network stack parameters. It can accumulate tuning requests
from multiple clients and merge requests.
The npt provides an hwbinder service used by wigig framework
(hosted inside system_server).
The npt also listens on a unix socket, this is used by vendor
components for backward compatibility with previous implementation.

8) sepolicy: add permissions to access wigig's snr_thresh sysfs

Part of FST functionality, fstman needs to access snr_thresh sysfs.

9) sepolicy: fix hostapd rules for FST

FST was broken by commit 3e2b4523
("sepolicy: Adding rule for cnd"). Object was changed from
wifi_vendor_wpa_socket to wpa_socket. However wifi_vendor_wpa_socket
provides access to /data/vendor/wifi/sockets where wpa_socket
provides access to /data/misc/wifi/sockets.

10) sepolicy: move definitions of wigig services

Move the definitions of wigig services from common
to private, otherwise they do not work in newer version
of Android.

Change-Id: Ia4d0770314706b97ee0fea8f36fe920f0d7103cf

11) sepolicy: remove duplicate definitions of wigig and wigigp2p

wigig and wigigp2p service definitions were duplicated in
common/service_contexts and private/service_contexts,
it caused problems with OTA build.

Change-Id: Ifaeb9ffdf65be44de3ef8d15c323e436b5e04d9f

12) sepolicy: add rules for on-demand insmod/rmmod of wigig driver

Add rules to allow wigig HAL service to insmod/rmmod the wigig module,
similar to the WIFI HAL. This is needed because the wigig chip
leaks power while wigig driver is loaded, so the driver must be
unloaded when wigig framework is disabled.

Change-Id: Id96f50020b3e7028b2c6bdd319383879565087c6

13) sepolicy: fixes for wigig SoftAP (hostapd)

Added some fixes to get wigig SoftAP working.
In recent version of Android hostapd now has its own HAL domain.
Update hostapd rules to refer to this new domain.

Also, there are few small updates to refer to proper types for
vendor files and sockets.

14) sepolicy: FST fixes

1. Restore access to hostapd global socket from fstman.
2. fstman now generates its configuration (fstman.ini) based
on system properties, so it needs read access to these.
3. wpa_supplicant global socket moved to vendor_wpa_wlan0,
so fstman (and other vendor services) can access it.

15) sepolicy: allow platform_app to read wigig properties

WigigSettings application needs to read wigig system property.

Change-Id: Ic5e28b454bfa261b4cbd91dc76b7e2267e1acb74

16) sepolicy: fix wigignpt access to network parameters

Add rule to fix problem with accessing sysfs network
parameters on recent android versions.
Based on this audit log:
avc: denied { search } for pid=1024 comm="wigignpt" name="net" dev="sysfs" ino=41025 scontext=u:r:wigignpt:s0 tcontext=u:object_r:sysfs_net:s0 tclass=dir permissive=0
