This is a necessary first step to finalizing the SELinux policy build
process.  The mapping_sepolicy.cil file is required to provide backward
compatibility with the indicated vendor-targeted version.

This still needs to be extended to provide N mapping files and corresponding
SHA256 outputs, one for each of the N previous platform versions with which
we're backward-compatible.

Bug: 36783775
Test: boot device with matching sha256 and non-matching and verify that
device boots and uses either precompiled or compiled policy as needed. Also
verify that mapping_sepolicy.cil has moved.

logcatd is the same as logcat, except that the -L flag, if supplied,
runs once, then the command re-runs itself without the -L flag with
the same argument set.  By introducing a logcatd daemon executable
we can solve the problem of the longish reads from pstore that
sometimes occur when the system is excessively busy spinning in a
foreground task starving this daemon as we absorb the delay in
an init service, rather than in an init exec.  This would not have
been efficiently possible without the introduction of liblogcat.

The CL splits /vendor labeling from /system. Which was allowing all
processes read, execute access to /vendor.

Following directories will remain world readable
 /vendor/etc
 /vendor/lib(64)/hw/

Following are currently world readable but their scope
will be minimized to platform processes that require access
 /vendor/app
 /vendor/framework/
 /vendor/overlay

Files labelled with 'same_process_hal_file' are allowed to be
read + executed from by the world. This is for Same process HALs and
their dependencies.

"tee" domain is a vendor domain. Hence its rules should live on the
vendor image.

What's left as public API is that:
1. tee domain exists and that it is permitted to sys_rawio capability,
2. tee_device type exists and apps are not permitted to access
   character devices labeled tee_device.

If you were relying on system/sepolicy automatically labeling
/dev/tf_driver as tee_device or labeling /system/bin/tf_daemon as
tee_exec, then you need to add these rules to your device-specific
file_contexts.

filesystem nodes. This is achieved by labelling all such sockets

On PRODUCT_FULL_TREBLE devices, non-vendor domains (coredomain) and
vendor domain are not permitted to connect to each other's sockets.
There are two main exceptions: (1) apps are permitted to talk to other
apps over Unix domain sockets (this is public API in Android
framework), and (2) domains with network access (netdomain) are
permitted to connect to netd.

This commit thus:
* adds neverallow rules restricting socket connection establishment,
* temporarily exempts the domains which are currently violating this
  rule from this restriction. These domains are grouped using the new
  "socket_between_core_and_vendor_violators" attribute. The attribute
  is needed because the types corresponding to violators are not
  exposed to the public policy where the neverallow rules are.
