381341f5f7 Fix environment variable assignment in init
The init process allows environment variables to be specified in
the rc script globally, via 'export', and for a specific process,
via the 'setenv' option.

However, the mechanism for assembling the environment simply
appended the new variable without checking whether it was already
defined, so it was not possible to overwrite an existing entry.
This patch fixes that behaviour.

Limitations and concerns:

The limit of a maximum number of 31 variables is unchanged.

Currently, most callers of "add_environment" do not check the return
value, but the function now logs the failure rather than failing
silently.

1bbef88e80 Add ability to adjust init log level at runtime.
+ Add a new property, sys.init_log_level, which can be set after init
  bootstrap. This will control the level at which init does prints to klog.

e4b7b294f3 Add ability to boot from charger mode.
Add the ability to boot up directly from charger mode, instead of forcing
charger mode to initiate a full restart to launch 'full' android. This
should shave a few seconds off of boot time on supported devices (just
manta for now).

ca8e66a8b0 Make init handle reboots
Move the responsibility for rebooting the system from the
reboot command to init. Init is in a better position to take
actions to bring the system down cleanly, including making sure
filesystems are mounted read-only.

The only UIDs which can perform an init triggered reboot are
root, system, and shell.

Modify the reboot command so that it calls into init to perform
the reboot. The reboot command no longer requires CAP_SYS_BOOT.

Remove the -n reboot option and code which supports it.  Anyone needing
to do an unclean shutdown can just do a 'echo c > /proc/sysrq-trigger'.

Modify adb so that it calls into init to perform a shutdown.

e096e36e50 Set the SELinux security label on new directories.
Automatically set the SELinux security label on directories created
by init.rc.  This avoids the need to separately call restorecon on
each such directory from the init.rc file.  Also restorecon /dev
and /dev/socket after initial policy load so that they are labeled
correctly before any other dev nodes or sockets are created.

96d0a4dda8 Extend and document the "wait" command
The wait command was currently implemented but
undocumented and only used internally. This change
adds a second option toi (optionally) override the default
timeout of 5 seconds.

The wait command can be used to wait for a file to appear
during the boot process, for example a disk or other device,
and is a better alternative than an unconditional sleep.

b54f39fdd9 init: Retain traditional restart behavior for critical and oneshot services.
Adds an SVC_RESTART state that's used for an explicit "restart" of a
running service.  This retains the traditional restart behavior for
critical and oneshot services (previously altered by 7e36edd8), whereby
these services are "simply restarted" instead of counting as a crash (for a
critical serivce) or going into the disabled state (for a oneshot service).

c5c51033c8 Load the persistent properties after decrypting the /data partition
Fix for bug 3415286.  The persistent properties are normally read early
in the boot process after /data is mounted.  However, for an encrypted
system, at that point /data is a tmpfs ramdisk.  This change adds a new
command to init (load_persist_props) to read the persistent properties,
and adds an action to init.rc to load the persistent properties.  This
action is triggered by setting a property in vold, but that's in a
different CL.
