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.

We can set it up earlier, and error reporting like this helped me find
the SELinux problem with the last change to this code.

This reverts commit b862bd00a4.
This change was fine but an earlier change it depended on was broken.
That change has been fixed and resubmitted.

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.

- On a N9 64-bit benchmark, the __android_log_is_loggable overhead
is roughly 500ns (1/2 of a syscall?)

The umount2 call was using the magic constant 2 which is
has a defined and proper macro in mount.h as MNT_DETATCH.

Certain platforms list their platform devices with a path other than
the current /devices or /devices/platform. Additionally, sometimes
these paths are a platform device themselves. An example are devices
with a path /devices/soc.0/... where /devices/soc.0 is also a platform
devices.
Instead of continuing to special case these path prefixes, we can
consider the entire path, given that no mmc or usb devices create
platform devices as subdevices, which they should not by their very
nature.
This keeps the symlinks for block devices named identically for
current platform devices and places them in /dev/block/<full path to
device> for devices in locations other than /devices or
/devices/platform, eg /dev/block/platform/soc.0/7824900.sdhci
This keeps the symlinks for character deviced named identically for
all cases.

Per-UID quota has a threshold of 12.5% of the total log size.
If less than that space is taken by the UID, then we
will not engage the pruning based on worst UID.

This doesn't fix the bug, but it does flatten the bug to the well-known
and long-standing "adb shell" doesn't return exit statuses, so when we
fix that, this one will fix itself.
