* changes:
ueventd: Fix up string handling in handle_*_device_event()

This CL disables module loading by writing 1 to
/proc/sys/kernel/modules_disabled when the property sys.boot_completed
is set to 1 by ActivityManagerService (at the broadcast of
PHASE_BOOT_COMPLETED).
Bug: 36515654
Test: tested on sailfish and verified that module loading is disabled in
userdebug and enabled in eng mode

The class early_hal is essentially for the keymaster hal which needs
to be up before vold tries to unlock a storage encryption key (FDE or
FBE). The current position is too early in the boot process, because
on devices with legacy HAL the wrapper service uses system properties
to find the legacy HAL.
This patch moves the start of the early_hal class to the late-fs trigger
action which runs right after the system property action.
Test: Manually tested and update tested on bullhead, sailfish, and
another device.

We have seen cases when threads in this cgroup not scheduled for more than
a few seconds in heavy workload situation and causing device freeze.
In Linux, multiple threads placed in ROOT cgroup cause the CPU resource to
be split per thread, rather than per group.
Currently we have many threads in ROOT cgroup, which makes threads in
bg_non_interactive cgroup to have "tiny" CPU resource other than 5%
quota defined.

This file describes how loader should set up
default namespace for different kind of binaries.
Note that vendor and some of system binaries are
not yet ready for this config to be enabled - they
rely on libraries they shouldn't be relying upon.

Motivation:
1. Reduce skew between userdebug and user builds.
2. Make the decision to mount debugfs on debug builds on a
per-device basis.
3. Prepare to not mount it at all to reduce the attack surface
of the kernel, reduce boot time, and free up memory.
4. Remove the selinux denial on devices that mount twice, i.e.
unconditionally in the device specific .rc file and in the
init-debug.rc file.
avc: denied { mounton } for path="/sys/kernel/debug" dev="debugfs"
ino=1 scontext=u:r:init:s0 tcontext=u:object_r:debugfs:s0
tclass=dir permissive=0
If desired, debugfs may be mounted in device specific rc files
instead.
Bug: 31856701
Bug: 35197529

Current init doesn't order the triggeres it scaned, and there is no
guarantee that general event trigger exec first and then event+property
triggers.
This CL will make sure netd started after post-fs-data trigger is done.

This change makes the init process to always attempts to enable
transient trigger for vibrator. This allows the exported properties to
change the ownership later at the on boot stage.

This prevents the shell user from injecting input as if it were coming
from an existing input device, which in turn makes it easier for malware
/ abuse analysis to detect when someone is injecting input via the
command line vs a real user using a device.

When vold mounts the encrypted /data partition, it first checks for and
kills processes that have open fds to the tmpfs placeholder at /data.
This resulted in a 20 second boot-time regression (vold's timeout period)
when tombstoned was started before vold.
Bug: http://b/34461270
Test: boot is faster, no messages from vold in console spew
Test: tombstoned still started by init

Also ensure that it uses the highest supported value, and
abort if the value is not above a minimum threshold.
Test: Tested against the curent kernel (maximum value of 2,
set to 0 by the kernel initially) and against a
modified kernel (maximum value of 4, set to 4 by the
kernel initially)

for audio_source function instance, there exist 2 function name here:
"audio_source.gs2" and "audio_source.gs3"
I believe this usb accessory audio name "audio_source.gs2" is a typo,
as there is no need to create another audio_source instance.

The SO_RCVBUFFORCE option requires the caller of uevent_create_socket()
to have net_admin capabilities.
Set platform default rcv/snd buffer sizes to 256kb that will always be
overridden by the device/target. However, it will allow
ueventd / healthd to use the uevent_create_socket() API w/o requiring
the net_admin capability.
Note: All devices override the buffer sizes according to the technology
maximum to at least ~8MB. So, the init.rc change here is to make sure
platform code can work w/o any overrides.
Test: no SELinux failures for healthd with 'net_admin' removed.
