This cleans up most of the size-related problems in system/core.
There are still a few changes needed for a clean 64-bit build,
but they look like they might require changes to things like the
fastboot protocol.

Add a service called "pre-recovery" which is normally stopped but can
be started by the system server when we want to go into recovery. It
will do any preparation needed (currently needed to handle update
packages that reside on an encrypted /data partition) and then set
sys.powerctl when it's ready to actually reboot.

Currently, the restorecon_recursive("/sys") call in
init.c takes approx 2 seconds on hammerhead. This change
reduces the delay to 1.2 seconds.
1) Avoid double stat call when using nftw (time savings
of 0.3 seconds)
2) Avoid the repeated calls to is_selinux_enabled() (time
savings of 0.5 seconds)
Avoid calling lsetfilecon if the file is already properly
labeled. This doesn't speed up the restorecon on /sys,
but it should help when handling files on /data.

By default ueventd creates device nodes under /dev based on the ueventd
DEVPATH. Several subsystems have special rules which are hardcoded in
devices.c. Moving forward these special rules should go in ueventd.rc.
Special rules have the syntax:
subsystem <s>
devname (uevent_devname|uevent_devpath)
[dirname <dir>]
Devices matching SUBSYSTEM=<s> will be populated under <dir>. dirname
is optional and defaults to /dev. If dirname is provided, <dir> must
start with "/".
If devname is uevent_devname, ueventd will create the device node as
<dir>/DEVNAME. DEVNAME may include intermediate subdirectories, which
ueventd will automatically create.
If devname is uevent_devpath, ueventd will use the legacy behavior of
computing DEVPATH_BASE=basepath(DEVPATH), and creating the device node
as <dir>/DEVPATH_BASE.
The new parsing code is based on init_parser.c, with small tweaks to
handle commands which don't fall under a section header.

Under certain conditions, poll() may raise the POLLERR
flag along with POLLIN, in which case the check for
(ufd.revents == POLLIN) results in an endless busy loop.
The following fix was applied to
hardware/libhardware_legacy/uevent/uevent.c
to fix a similar bug:

Don't queue actions for "on property=*" if the property does not exist.
This fixes these errors on boot:
init: property 'sys.powerctl' doesn't exist while
expanding '${sys.powerctl}'
init: powerctl: cannot expand '${sys.powerctl}

The Linux kernel supports command lines up to 2048 bytes on x86,
see COMMAND_LINE_SIZE in asm/setup.h.
If any androidboot.xxxx arguments were past the 1024 byte limit
here, they were lost.

Create a new "androidboot.selinux" option, to control how userspace
handles SELinux. This kernel command line can have three options:
* disabled
* permissive
* enforcing
"disabled" completely disables userspace support for SELinux. No
policy is ever loaded, nor is the SELinux filesystem /sys/fs/selinux
ever mounted.
"permissive" loads the SELinux policy, but puts SELinux into
permissive mode. SELinux policy violations are logged, but not rejected.
"enforcing", the default, loads the SELinux policy, and places
SELinux into enforcing mode. Policy violations are rejected.
This change addresses post review comments for change
b710ed21de .

When init starts up, immediately put SELinux into enforcing mode.
This is currently a no-op. We currently have everything in the
unconfined domain, so this should not break anything.
(if it does, I'll roll it back immediately)
If the kernel doesn't have SELinux support compiled in, then
don't try loading a policy and continue without SELinux protections.
