Nick Kralevich f667a3247a init: get rid of the remaining double mounts 
Don't double mount /dev and its subdirectories anymore. Instead, the
first stage init is solely responsible for mounting it.

Don't have init prepare the property space. This is the responsibility
of the second stage init.

Don't have SELinux use the property space to determine how we should
be running. Instead, create a new function and extract the data we
need directly from /proc/cmdline. SELinux needs this information in
the first stage init process where the property service isn't available.

Nick Kralevich e34577ce1b init: use SELinux /dev/null if available 
SELinux provides it's own /dev/null character device at
/sys/fs/selinux/null. This character device is exactly the same
as /dev/null, including the same major/minor numbers, and can
be used wherever /dev/null is used.

Use /sys/fs/selinux/null instead of trying to create our own
/dev/__null__ device. This moves us one step closer to eliminating
all uses of mknod() by init.

/sys/fs/selinux/null is only available once the /sys/fs/selinux filesystem
is mounted. It's not available to the first stage init, so we
still have to fall back to mknod then.

Nick Kralevich 9dec93bfeb init: don't double mount /proc and /sys 
The first stage init mounts /proc and /sys, and then the second
stage init also mounts /proc and /sys on top of the existing mount.
Only mount these two directories once, in the first stage init.

Not yet fixed: the double mounting of /dev. Removing the double
mounting doesn't work right now because both init stages are trying
to create a property space, and if the double mount of /dev goes away,
the property service in the second stage init fails to work.

Nick Kralevich eedbe81f75 init: fix write_file checkreqprot logic error 
write_file() returned -errno on error, not -1. Callers who check for
-1 would falsely believe that the write was successful when it wasn't.
Fixup write_file so that it return -1 on error consistent
with other functions.

Not just because it's what the cool kids are doing --- it also lets us
simplify the inner loop and decouple it from whatever systems want to
be woken to perform some activity if there's data to be read on some fd.

Currently this is just used to clean up the existing signal handling,
keychord, and property service code.

All the code that was being delayed does is create a socket. We can
do that straight away, avoid the overhead, and simplify our main loop.

The keychord fd, on the other hand, seems a little tricky. It looks
like /dev/keychord isn't immediately available, at least not on N9;
we have to wait for ueventd to set us up the bomb.
