* changes:
  Soong module for selinux files including board-specific directories.
  Soong module selinux compat maps

The tags property is (and has always been) unused by Soong. The property has
been defined as a list of strings, and the `androidmk` converted any
LOCAL_MODULE_TAGS entries over to it, but we've never done anything with it.

In preparation for removing the definition from Soong, I'm removing it from all
Android.bp files in the tree.

Since this has never done anything, this is a no-op, but if you really did want
the Android.mk behavior, the proper way to define a module to be installed in
userdebug / eng builds is to use PRODUCT_PACKAGES_DEBUG or PRODUCT_PACKAGES_ENG
in the appropriate product makefile.

Test: remove `tags` from Soong, see errors go away.

se_filegroup is used to export selinux files from board-specific
directories (e.g. device/google/wahoo/sepolicy).

Use se_filegroup module to export partner extension of compatibility
mapping to build logic in system/sepolicy.

(cherry picked from commit 4be28894)

Files in /proc/net leak information. This change is the first step in
determining which files apps may use, whitelisting benign access, and
otherwise removing access while providing safe alternative APIs.

To that end, this change:
* Introduces the proc_net_type attribute which will assigned to any
new SELinux types in /proc/net to avoid removing access to privileged
processes. These processes may be evaluated later, but are lower
priority than apps.
* Labels /proc/net/{tcp,tcp6,udp,udp6} as proc_net_vpn due to existing
use by VPN apps. This may be replaced by an alternative API.
* Audits all other proc/net access for apps.
* Audits proc/net access for other processes which are currently
granted broad read access to /proc/net but should not be including
storaged, zygote, clatd, logd, preopt2cachename and vold.

* Note on cherry-pick: Some of the dependent changes are not in AOSP.
In order to keep hostapd running correctly in AOSP, I've modified this
change to only include policy additions.

Change sepolicy permissions to now classify hostapd as a HAL exposing
HIDL interface.

Vendor public libs are exposed to apps (not system), and their ABI
stability is guaranteed by vendor. Introducing new selinux type so that
we don't conflate concepts of same-process HAL and vendor public lib.
The former is exposed to all domains, while the latter should only be
acessible by apps.
