fork() subprocesses to handle uevents in parallel.
This reduces coldboot time on bullhead from ~446ms to ~230ms.
This reduces coldboot time on sailfish from ~690ms to ~360ms.
This reduces coldboot time on ryu from ~187ms to ~122ms.

devices.cpp handles too many things for creating one class. This
change breaks it up into various files and classes.
* Parsing is moved to ueventd_parser.cpp
* Reading from the uevent socket and Cold booting is moved to a
UeventListener class, in uevent_listener.cpp
* Firmware handling is moved to firmware_handler.cpp
* The remaining contents form a DeviceHandler class within devices.cpp

An forward declaration for a function that was removed in later
patchsets was merged anyway. Since it's not used anywhere, this CL
removes it.

Previously init_parser.cpp was made generic and capable of parsing any
number of differently named 'sections' or prefixed lines. We now use
these capabilities to do the parsing for ueventd.

Test: boot bullhead and ensure the right /dev nodes exist
with the right permissions set
Test: verify no boot time difference

in std::vector instead of the C list.

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.

- Clean up the paths for ro.revision and ro.hardware parsing
- Use ro.hardwre in ueventd instead of parsing the kernel command line
(cherry-pick of 38b340a52f8e864650db8bae1eb88d5c00485db0.)
