The service "storaged" implememnts a dump() interface for
dumpsys, and thus it needs to write its state to the fd
provided by dumpstate.

To correct this, and fix dumpstate, allow the permission.

Fixes:
avc: denied { use } for pid=3298 comm="dumpsys" path="pipe:[33470]" dev="pipefs" ino=33470 scontext=u:r:storaged:s0 tcontext=u:r:dumpstate:s0 tclass=fd permissive=0

Test:
With a device that has storaged, issue the command:
$ adb shell dumpstate

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.
