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.

To support external storage devices that are dynamically added and
removed at runtime, we're changing /mnt and /storage to be tmpfs that
are managed by vold.
To support primary storage being inserted/ejected at runtime in a
multi-user environment, we can no longer bind-mount each user into
place. Instead, we have a new /storage/self/primary symlink which
is resolved through /mnt/user/n/primary, and which vold updates at
runtime.
Fix small mode bugs in FUSE daemon so it can be safely mounted
visible to all users on device.

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 systrace permissions from init.trace.rc and the "class_start core"
which launches surfaceflinger are both in an "on boot" section. However,
the init.trace.rc commands are parsed after all commands in init.rc.
This means that "class_start core" is executed before the chmod command
which allows processes to write to trace_marker. If any services
execute their first trace command before the chmod occurs, then that
service won't be able to write traces until the service is restarted.
To fix this, run all of the init.trace.rc commands in the "early-boot"
section to ensure they are completed first.
