c6c26ed781 Clean up property service initialization.
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.

9042cae40b Clean up init signal handling a little.
We can set it up earlier, and error reporting like this helped me find
the SELinux problem with the last change to this code.

c7ca9dd6c8 Revert "Revert "Remove now-unusable 'setcon' command.""
This reverts commit b862bd00a4.

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

f65730e620 Revert "Revert "Make init re-exec itself for its SELinux domain transition.""
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.

1225a61f0a init: consider all platform devices for find_platform_device
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.

4f673306fc Setup signal handler before any exec command
Fixes init deadlock when an exec command was called
in an on-init section.

The exec command handling relies on that the signal handler
mechanism is working to know when to continue executing
commands.

within our power to fix).

747383649c Fix clang build by removing unused locals.
Also don't manually set FD_CLOEXEC on a socket that's always opened
with SOCK_CLOEXEC. (None of the other callers to the function do this.)

Also move locals to where they're first used to help prevent more of this
kind of breakage.

da40c00137 Log more timing information from init.
Also make important events in init's life NOTICE rather than INFO,
and ensure that NOTICE events actually make it to the kernel log.

Also fix the logging so that if you have a printf format string
error, the compiler now catches it.

Also give messages from init, ueventd, and watchdogd distinct tags.
(Previously they'd all call themselves "init", and dmesg doesn't
include pids, so you couldn't untangle them.)

Also include the tag in SELinux messages.
