The system property "vold.post_fs_data_done" is used by init and vold to
communicate with each other in order to set up FDE on devices that use
FDE. It needs to be gettable and settable by vold, and settable by init
and vendor_init. This was the case in Android 11 and earlier; however,
the change
https://android-review.googlesource.com/c/platform/system/sepolicy/+/1277447
("Rename exported and exported2 vold prop") broke this by giving this
property the type "vold_config_prop", which made it no longer settable
by vold.
Since none of the existing property types appear to be appropriate for
this particular property, define a new type "vold_post_fs_data_prop" and
grant the needed domains permission to get/set it.
This is one of a set of changes that is needed to get FDE working again
so that devices that launched with FDE can be upgraded to Android 12.

This patch adds ro.product.enforce_debugfs_restrictions to
property_contexts. When the property is set to true in non-user builds,
init mounts debugfs in early-init to enable boot-time debugfs
initializations and unmounts it on boot complete. Similarly dumpstate
will mount debugfs to collect information from debugfs during bugreport
collection via the dumpstate HAL and unmount debugfs once done. Doing
so will allow non-user builds to keep debugfs disabled during runtime.

Split gsi_metadata_file into gsi_metadata_file plus
gsi_public_metadata_file, and add gsi_metadata_file_type attribute.
Files that are okay to be publicly readable are labeled with
gsi_public_metadata_file. Right now only files needed to infer the
device fstab belong to this label.
The difference between gsi_metadata_file and gsi_public_metadata_file is
that gsi_public_metadata_file has relaxed neverallow rules, so processes
who wish to read the fstab can add the respective allow rules to their
policy files.
Allow gsid to restorecon on gsi_metadata_file to fix the file context of
gsi_public_metadata_file.

Previously we would mount OTA images with a 'context=...' mount
option. This meant that all selinux contexts were ignored in the ota
image, limiting the usefulness of selinux in this situation. To fix
this the mount has been changed to not overwrite the declared contexts
and the policies have been updated to accurately describe the actions
being performed by an OTA.

In order to test the platform in emulators that are orders of magnitude
slower than real hardware we need to be able to avoid hitting timeouts
that prevent it from coming up properly. For this purpose introduce
a system property, ro.hw_timeout_multiplier, which may be set to
an integer value that acts as a multiplier for various timeouts on
the system.
