8d24e01ba8 Allow odrefresh to relabel staging files to apex_art_data_file.
This will allow odrefresh to move files from staging dir to output dir
instead of copying.

Test: -
  1. Patch https://r.android.com/2991838
  2. atest odsign_e2e_tests_full

90b7b00391 Allow composd to run fd_server
Besides the basic execution that is similar to the (deprecating)
odrefresh case, fd_server also needs to be able to create and change
files in the output directory.

8788f7afe2 Split composd's service in two
They are served by the same process but have different clients:
- the main interface is exposed to system server;
- the internal interface is called by odrefresh when spawned by composd.

ec4a90f59c Enable odrefresh to work with composd.
composd spawns odrefresh in its usual domain. odrefresh then spawns
fd_server in a different domain, and makes binder calls back to
composd to perform individual compilation steps.

fd_server is fairly generic, and part of the virt APEX, but this
instance is specific to composd (e.g. it has access to ART files), so
I named the domain composd_fd_server.

d3438b0f3c Allow composd to run odrefresh
Also allow odrefresh to run pvm_exec to talk to the CompOS VM.

And I moved the dontaudit & neverallow rules to the bottom while I was here.

0b2ca6c22c Enable ART properties modularization
ART is becoming a module and we need to be able to add new properties
without modifying the non updatable part of the platform:

- convert ART properties to use prefix in the namespace of
[ro].dalvik.vm.
- enable appdomain and coredomain to read device_config properties
that configure ART

Test: boot

7c6b3eb963 Add odrefresh_data_file for odrefresh metrics
Metrics are written to /data/misc/odrefresh by odrefresh during early
boot, then native code in ART system_server initialization passes them
to statsd and deletes the metrics files. This hand-off is necessary
because statsd does not start until after odsign and odrefresh have run.

06edcd8250 Add SELinux policy for using userfaultfd
ART runtime will be using userfaultfd for a new heap compaction
algorithm. After enabling userfaultfd in android kernels (with SELinux
support), the feature needs policy that allows { create ioctl read }
operations on userfaultfd file descriptors.

Bug: 160737021

46c2aad205 odrefresh.te: use create_rw_perms for apex_art_data_file:file

that it is now launched from init which sets a restrictive umask on

8f75f76fbd Permissions for odrefresh and /data/misc/apexdata/com.android.art
odrefresh is the process responsible for checking and creating ART
compilation artifacts that live in the ART APEX data
directory (/data/misc/apexdata/com.android.art).

There are two types of change here:

1) enabling odrefresh to run dex2oat and write updated boot class path
   and system server AOT artifacts into the ART APEX data directory.

2) enabling the zygote and assorted diagnostic tools to use the
   updated AOT artifacts.

odrefresh uses two file contexts: apex_art_data_file and
apex_art_staging_data_file. When odrefresh invokes dex2oat, the
generated files have the apex_art_staging_data_file label (which allows
writing). odrefresh then moves these files from the staging area to
their installation area and gives them the apex_art_data_file label.

Bug: 160683548
Test: adb root && adb shell /apex/com.android.art/bin/odrefresh
