Allow the otapreopt rename script to read file attributes. This is
being used to print the aggregate artifact size for diagnostic
purposes.

The recovery flow for A/B devices allows to sideload an OTA downloaded
to a desktop and apply from recovery. This patch allows the "recovery"
context to perform all the operations required to apply an update as
update_engine would do in the background. These rules are now extracted
into a new attributte called update_engine_common shared between
recovery and update_engine.

Needed for legacy VPN access.

Note that ioctl whitelisting only uses the type and command fields
of the ioctl so only the last two bytes are necessary, thus 0x40047438
and 0x7438 are treated the same.

Vendor apps are usually not preopted, so A/B dexopt should pick
them up. update_engine is not mounting the vendor partition, so
let otapreopt_chroot do the work.

This change gives otapreopt_chroot permission to mount /vendor
into the chroot environment.

The new A/B OTA artifact naming scheme includes the target slot so
that the system is robust with respect to unexpected reboots. This
complicates the renaming code after reboot, so it is moved from the
zygote into a simple script (otapreopt_slot) that is hooked into
the startup sequence in init.

Give the script the subset of the rights that the zygote had so that
it can move the artifacts from /data/ota into /data/dalvik-cache.
Relabeling will be done in the init rc component, so relabeling
rights can be completely removed.

To include target slot names in the naming of A/B OTA artifacts,
and new path has been implemented. Instead of passing through
the system server and forking off of installd, otapreopt_chroot
is now driven directly from the otapreopt script.

Change the selinux policy accordingly: allow a transition from
postinstall to otapreopt_chroot, and let otapreopt_chroot inherit
the file descriptors that update_engine had opened (it will close
them immediately, do not give rights to the downstream executables
otapreopt and dex2oat).

Previously appdomains allowed to execute off of /data
where whitelisted. This had the unfortunate side effect of
disallowing the creation of device specific app domains
with fewer permissions than untrusted_app. Instead grant
all apps a neverallow exemption and blacklist specific app
domains that should still abide by the restriction.

This allows devices to add new app domains that need
/data execute permission without conflicting with this rule.
