Grant installd the policies to recursively delete
the foreign-dex folder when removing a user. Otherwise
the user cleanup will partially fail and cause a boot loop
when the userId is reused as some later point.

Commit: b144ebab added the sysfs_usb
type and granted the read perms globally, but did not add write
permissions for all domains that previously had them.  Add the ability
to write to sysfs_usb for all domains that had the ability to write to
those files previously (sysfs).

Address denials such as:

Per "man socket":

  SIOCGSTAMP
  Return a struct timeval with the receive timestamp of the last packet
  passed to the user. This is useful for accurate round trip time
  measurements. See setitimer(2) for a description of struct timeval.
  This ioctl should only be used if the socket option SO_TIMESTAMP is
  not set on the socket. Otherwise, it returns the timestamp of the last
  packet that was received while SO_TIMESTAMP was not set, or it fails
  if no such packet has been received, (i.e., ioctl(2) returns -1 with
  errno set to ENOENT).

Addresses the following denial:

Bug: 22775369

Some legitimate functionality currently requires direct sysfs access
that is not otherwise possible via the android APIs.  Specifically,
isochronous USB transfers require this direct access, without which USB
audio applications would noticibly suffer.

Grant read access to the usb files under /sys/devices to prevent this
regression.

This allows the shell user to control whether unprivileged access to
perf events is allowed.

To enable unprivileged access to perf:

    adb shell setprop security.perf_harden 0

To disable it again:

    adb shell setprop security.perf_harden 1

This allows Android to disable this kernel attack surface by default,
while still allowing profiling tools to work automatically. It can also
be manually toggled, but most developers won't ever need to do that if
tools end up incorporating this.

* changes:
  Sepolicy: Allow debuggerd to dump backtraces of Bluetooth
  Sepolicy: Refactor long lines for debuggerd backtraces

Since kernel 4.1 ftrace is supported as a new separate filesystem. It
gets automatically mounted by the kernel under the old path
/sys/kernel/debug/tracing. Because it lives now on a separate device
some sepolicy rules need to be updated. This patch is doing that. Most
of the rules are created based on a conversation happened on the SELinux
Android mailing list:

http://comments.gmane.org/gmane.comp.security.seandroid/2799



Note, that this also needs 3a343a1 from the 4.4 branch in kernel/common.
Also note that when tracefs is auto mounted by the kernel, the kernel
does not use the "mode" parameter specified to mount debugfs for
tracefs. So an extra line like

   chmod 0755 /sys/kernel/debug/tracing

is necessary in init.${ro.hardware}.rc after debugfs was mounted.

untrusted_app lost the ability to read files labeled as sysfs to prevent
information leakage, but this is trivially bypassable by spawning an
isolated app, since this was not taken away from isolated app.
Privileges should not be gained by launching an isolated app, and this
one directly defeats that hardeneing. Remove this access.
