These permissions allow the system server to create and
bind a UDP socket such that it gains the SOCK_BINDPORT_LOCK.
(ref: af_inet.c - inet_bind()) This prevents the user from
disconnecting the socket, which would create a security
vulnerability. The user may then use the provided socket,
which is always IPv4/UDP, for IKE negotiation. Thus, an
un-trusted user app must be able to use the socket for
communication.
-ALLOW: read, write, connect, sendto, and recvfrom.
-NEVERALLOW: anything else

Create PLATFORM_SEPOLICY_VERSION, which is a version string to represent
the platform sepolicy of the form "NN.m" where "NN" mirrors the
PLATFORM_SDK_VERSION and "m" is a policy-based minor version that is
incremented with every policy change that requires a new backward-compatible
mapping file to be added to allow for future-proofing vendor policy against
future platform policy.

Test: Device boots when sha256 doesn't match and compilation is forced.
Change-Id: I4edb29824f2050a5a6e1bc078c100cf42e45c303
The sepolicy version takes SDK_INT.<minor> format. Make sure our
'current' policy version reflects the format and make it '100000.0'.
This ensures any vendor.img compiled with this will never work with
a production framework image either.
Make version_policy replace the '.' in version by '_' so secilc is
happy too.
This unblocks libvintf from giving out a runtme API to check vendor's
sepolicy version. The PLAT_PUBLIC_SEPOLICY_CURRENT_VERSION will
eventually be picked up from the build system.

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.

Currently update_verifier only verifies the blocks when dm-verity is in
'enforcing' mode; and dm-verity will reboot the device upon detection of
errors. However, sometimes the verity mode is not guaranteed to be
correct. When mode is 'eio' for example, dm-verity will not trigger
a reboot but rather fail the read. So update_verifier need to take the
responsibility to reboot the device. Otherwise the device will continue
to boot without setting the flag "isSlotMarkedSuccessful".

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.
