currently requires to communicate with the parent by a pipe, before

When we cut down microdroid policy we removed a whole lot of
neverallow rules that were in public/domain.te. Many of these are
irrelevant, but there are some that look quite important. So this CL
restores many of them. This makes no immediate difference (none of
these rules are currently violated, except as mentioned below), but it
might catch mistakes, or at least make us stop and think before
introducing potentially risky policy changes.
Process:
- Paste in all the neverallow rules from public/domain.te in Android
policy.
- Delete all references to non-existent labels.
- Delete everything makred full-trebly-only,
I also deleted some attributes we clearly don't need, and hence
associated neverallows. (I suspect there are more attributes we could
remove.)
And then I fixed a neverallow violation for microdroid_payload - we
were allowing it unrestricted ioctl access.

extra_apk_file is a new label only for APK files passed to microdroid.
microdroid_manager will create directories under /mnt/extra-apk/, and
zipfuse will mount APK block devices to the directories.
Currently only payload can read the files.

This is the context when health HAL runs in offline

This has the same permissions as the health HAL, but

composd in responsible to prepare the staging directory for odrefresh
(in the VM) to write the output to. Temporary output should be put in a
staged directory with a temporary apex_art_staging_data_file context.
When a compilation is finished, the files can then be moved to the final

PEM files are ASCII-encoded, open them as text file (as opposed to
binary). Avoid relying on __del__. Introduce a prologue and epilogue
methods to emit the <policy> tag only once per output.
