First stage mount in init currently attempts to regenerate uevents for
specific devices to create the corresponding dev nodes. However, this
is racy as first stage mount happens early in the boot process and
it's possible that some of these devices have not yet been created by
the kernel.
To fix this issue, init will poll on the uevent socket for up to 10
seconds waiting for the kernel to create the required device. It will
return false and panic if this 10 second timeout passes.
Note that the same uevent socket is used in the uevent regeneration
and the polling code, so there is no race if the device is created
after the uevent regeneration and before polling starts; the first
poll will pick up the device.

I'll come back and remove klog_init when I've removed other calls to it.

Test: booted N9, looked at "adb shell dmesg" output.
Switch ueventd to use the grp.h and pwd.h family of
functions for converting strings to uids. This removes the
need for using android_filesystem_config.h.

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.
