Services definitions for core services are now bundled with the source
for the service itself in the form of <service name>.rc. These
individual .rc files are now located in /system/init/... and are
parsed when the system partition is mounted.

This CL adds a trigger and a service so that Systrace can be used
for tracing events during boot.
persist.debug.atrace.boottrace property is used for switching on
and off tracing during boot. /data/misc/boottrace/categories
file is used for specifying the categories to be traced.
These property and file are rewritten by Systrace when the newly
added option --boot is specified.
Here is an example of tracing events of am and wm catetories
during boot.
$ external/chromium-trace/systrace am wm --boot
This command will cause the device to reboot. Once the device has
booted up, the trace report is created by hitting Ctrl+C.
As written in readme.txt, this mechanism relies on persistent
property, so tracing events that are emitted before that are not
recorded. This is enough for tracing events after zygote is
launched though.
This only works on userdebug or eng build for security reason.

Ensure that /data/anr always exists. This allows us to eliminate
some code in system_server and dumpstate. In addition, this change
solves a common problem where people would create the directory
manually but fail to set the SELinux label, which would cause
subsequent failures when they used the directory for ANRs.

Folders in the root directory are now created during the build,
as we may be building without a ramdisk, and when we do that,
the root directory will be read-only. With those changes,
these mkdirs will never need to run.

/system/bin/uncrypt needs to be triggered to prepare the OTA package
before rebooting into the recovery. Separate pre-recovery (uncrypt)
into two services: uncrypt that does the uncryption work and
pre-recovery that actually reboots the device into recovery.
Also create /cache/recovery on post-fs in case it doesn't exist.

An automatic domain transition is already defined by SELinux
policy. Avoid having redundant information on the exec line.
This commit depends on commit 17fff893c0
which made the SELinux process label optional.

- logpersistd is defined as a thread or process in the context of the
logd domain. Here we define logpersistd as logcat -f in logd domain
and call it logcatd to represent its service mechanics.
- Use logcatd to manage content in /data/misc/logd/ directory.
- Only turn on for persist.logd.logpersistd = logcatd.
- Add logpersist.start, logpersist.stop and logpersist.cat debug
class executables, thus only in the eng and userdebug builds.
ToDo: Wish to add Developer Options menu to turn this feature on or
off, complicated by the fact that user builds have no tools with
access rights to /data/misc/logd.

This reverts commit 4217374611.
It turns out that the kernel passes any unrecognized arguments on to init,
and (at least) N6 and N9 have such arguments. My lazy check of argc was
thus insufficient to recognize what stage of init we were in, so we'd
skip to stage 2 and not set up SELinux. And apparently you can get a
very long way with SELinux off... We'll fix that in a later change.

tzdatacheck is exec'd from init.rc early in boot just after /data is
mounted. It checks to make sure that the tz rule data in /data
is newer than the version in /system. If the data is older it is
deleted. This is to address problems with earlier tz rule updates
that occurred: after an OTA upgrade previous updates in /data
would override newer versions in the system partition.
Includes change to init.rc neccessary to run it at boot time. Other
changes are in external/selinux.

The earliest point we can start logd is after /system is mounted.
Ideally on post-fs-system (does not exist), post-fs will do.
As insurance, we will also make sure logd is started if a
logd-reinit is requested. This results in logd starting at least
4 processes earlier than it does currently, with a tighter
grouping of threads which means we are taking advantage of a
lighter CPU load at the time, rather than taking cycles during
heavy activity during core startup.

Also make important events in init's life NOTICE rather than INFO,
and ensure that NOTICE events actually make it to the kernel log.
Also fix the logging so that if you have a printf format string
error, the compiler now catches it.
Also give messages from init, ueventd, and watchdogd distinct tags.
(Previously they'd all call themselves "init", and dmesg doesn't
include pids, so you couldn't untangle them.)
Also include the tag in SELinux messages.

bootchart uses a file on the data partition to decide if it should collect
data for bootchart, but the data partition will be mounted by the mount_all
command in the "on fs" section, and it will be only added into the action
queue when command "trigger fs" is executed, but that's after the
bootchart_init action (late_init).
This change makes bootchart_init a builtin command of init,
and make it executed as the first command of "on post-fs" section
which will be triggered after the "on fs" section.
This change also refactors the bootchart code to all be in bootchart.cpp.

The upstream kernel now includes support for emulating legacy AArch32
instructions on ARMv8 devices. By default this framework emulates
deprecated instructions but not obsolete instructions.
Android requires support for the obsolete SWP and SWPB instructions on
all ARM devices, so override this default for the swp emulation hook.
