This gid allows processes full access to public areas of external
storage. This includes the following:
1. EmulatedVolumes: All files and directories excluding the app
specific directories under Android/
2. PublicVolumes: Including 'unreliable' volumes (USB OTG) that are
not typically accesible to ordinary apps
Apps with the MANAGE_EXTERNAL_STORAGE permission will automatically
have this gid

For a Q APEX built with use_vendor, rather than using AIDL to talk to
ashmemd, it would directly open /dev/ashmem. R libcutils does ashmem
differently, but in order to allow R-built APEXes to replace this
category of APEXes, falling back to /dev/ashmem.

This is to deprecate the sysprop change notification in atrace.
After this change, processes will only update their enabled tags
at the first atrace event. Previously we reloaded the tags as a
result of the sysprop changed Binder notification, which woke up
every process in the system.

Update fs_config tests for the new behavior in
a8eb00720c.
Before the above CL, fs_config_cmp() would match any partition prefix
to any path, even if there is not a logical relationship between them.
For example, these two lines in the test the demonstrate the changed
behavior:
{ true, "vendor/lib", "system/vendor/lib/hw", true },
{ true, "system/vendor/lib", "vendor/lib/hw", true },
The first line should match and does; it is testing that files located
at system/vendor/lib/hw are matched by an fs_path_config entry
specified as vendor/lib. This is to allow for applying the policy we
have for the vendor partition to files in /system/vendor in the case
that there is no vendor partition.
The second line should not match. This is testing that a file
that's located at vendor/lib/hw is matched by an fs_path_config entry
specified as system/vendor/lib. This is backwards; we do not want to
have policy specified for system/vendor to impact policy for the
vendor partition.
Also, we never have any relationships from /system/oem to /oem or
/system/odm to /odm, so these are logically unrelated and should fail
to match. We do however have a relationship from /vendor/odm to /odm,
so this test is added.
Test: libcutils unit tests pass on CF

This change is part of a topic that moves the recovery resources from the
system partition to the vendor partition, if it exists, or the vendor directory
on the system partition otherwise. The recovery resources are moving from the
system image to the vendor partition so that a single system image may be used
with either an A/B or a non-A/B vendor image. The topic removes a delta in the
system image that prevented such reuse in the past.
The recovery resources that are moving are involved with updating the recovery
partition after an update. In a non-A/B configuration, the system boots from
the recovery partition, updates the other partitions (system, vendor, etc.)
Then, the next time the system boots normally, a script updates the recovery
partition (if necessary). This script, the executables it invokes, and the data
files that it uses were previously on the system partition. The resources that
are moving include the following.
* install-recovery.sh
* applypatch
* recovery-resource.dat (if present)
* recovery-from-boot.p (if present)
This change moves the recovery resources to vendor in libcutils/fs_config.cpp
and removes the flash_recovery service from rootdir/init.rc. This service moved
to a vendor init.rc file in bootable/recovery/applypatch.
Bug: 68319577
Test: Ensure that recovery partition is updated correctly.

Having libcutils ask ashmemd for ashmem fds results in unsatisfactory
performance/memory overhead. Introduce a duplicate of /dev/ashmem and
route to it instead.
Our goal remains as before, namely, use SELinux to phase out usage of
ashmem that doesn't go through libcutils.
