On some devices there is a slight delay between the creation of "/dev/bus"
and "/dev/bus/usb". Previously, the code assumed that both are created in the
same time which caused "watch_existing_subdirs" to fail and libusbhost to stop
working until the device is rebooted. The fix will setup an inotify event on the
creation of the "bus/usb" so it will not be missed once it's created.

The group ownership of the package database
/data/system/packages.list read by run-as was changed in
977a9f3b1a from "system" to
"package_info". run-as currently changes its effective group to
"system" and is thus unable to read the database.
This CL fixes the issue by making run-as change its effective group
to "package_info" for reading the package database.

The Linux RNG may have little entropy during boot. As more and more
devices have a Hardware RNG, we mix in 512 bytes from Hardware RNG
(if present) into Linux RNG early during boot (after
wait_for_coldboot_done and before property_service_init actions in
init).
To avoid having to trust the output of Hardware RNG, we do not mix it
into the Linux RNG's primary pool or increase the Linux RNG's entropy
estimates.

The fuse_open_out structure returned to the kernel by handle_opendir()
was not properly initializing all the fields. The symptom was recursive
ls (ls -R) failing on the emulated sdcard filesystem, because rewinddir(3)
was failing with ESPIPE.

The legacy internal layout places users at the top-level of the
filesystem, so handle with new PERM_LEGACY_PRE_ROOT when requested.
Mirror single OBB directory between all users without requiring fancy
bind mounts by letting a nodes graft in another part of the
underlying tree.
Move to everything having "sdcard_r" GID by default, and verify that
calling apps hold "sdcard_rw" when performing mutations. Determines
app group membership from new packages.list column.
Flag to optionally enable sdcard_pics/sdcard_av permissions
splitting. Flag to supply a default GID for all files. Ignore
attempts to access security sensitive files. Fix run-as to check for
new "package_info" GID.

This adds support for parsing RTM_NEWADDR and RTM_DELADDR
netlink messages received on netd's netlink socket and
formatting them them so NetlinkHandler can process them.
Address changes are notified in subsystem "address". Interface
changes, which used to be notified in subsystem "net", are now
notified in subsystem "interface" to avoid confusion.

default search for arbitrary power supplies with the named paths.

Changes the FUSE daemon to synthesize an Android-specific set of
filesystem permissions, even when the underlying media storage is
permissionless. This is designed to support several features:
First, apps can access their own files in /Android/data/com.example/
without requiring any external storage permissions. This is enabled
by allowing o+x on parent directories, and assigning the UID owner
based on the directory name (package name). The mapping from package
to appId is parsed from packages.list, which is updated when apps are
added/removed. Changes are observed through inotify. It creates
missing package name directories when requested and valid.
Second, support for separate permissions for photos and audio/video
content on the device through new GIDs which are assigned based on
top-level directory names.
Finally, support for multi-user separation on the same physical media
through new /Android/user/ directory, which will be bind-mounted
into place. It recursively applies the above rules to each secondary
user.
rwxrwx--x root:sdcard_rw /
rwxrwx--- root:sdcard_pics /Pictures
rwxrwx--- root:sdcard_av /Music
rwxrwx--x root:sdcard_rw /Android
rwxrwx--x root:sdcard_rw /Android/data
rwxrwx--- u0_a12:sdcard_rw /Android/data/com.example
rwxrwx--x root:sdcard_rw /Android/obb/
rwxrwx--- u0_a12:sdcard_rw /Android/obb/com.example
rwxrwx--- root:sdcard_all /Android/user
rwxrwx--x root:sdcard_rw /Android/user/10
rwxrwx--- u10_a12:sdcard_rw /Android/user/10/Android/data/com.example
These derived permissions are disabled by default. Switched option
parsing to getopt().

This change adds a "verify" fs_mgr flag specifying that
the device in question should be verified.
Devices marked with this flag are expected to have a
footer immediately after their data containing all
the information needed to set up a verity instance.

Making an object Flattenable doesn't force it to
become virtual anymore. For instance, Fence and GraphicBuffer
are now non-virtual classes.
Also change Flatennable protocol a bit so that it updates
its parameters (pointers, sizes) to make it easier
to implement a flattenable in terms of other flattenables.

In b2cac4ff37ed2a3521efb307b807b12f649634b8, the last
reference to property_get was removed, but the include
file remained. Remove it.
This is causing me unrelated problems.

when libutils is statically linked, the ordering of the static
initializer is not guaranteed and therefore it's unsafe to use
empty static strings: e.g.:
static String8 sThisStaticStringIsNotSafe;
instead, this new constructor can be used:
static String8 sThisStaticStringIsSafe(kEmptyString);

This is just to support the watchdog to give it a faster
way to determine if a thread is deadlocked without having
to post a message to it.
