init: poll in first stage mount if required devices are not found
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.

Move restorecon() of /sys from init to ueventd.
ueventd already does restorecon() for /sys/{block,class,devices}, so
instead of duplicating this effort with init, move the restorecon()
that init does for all of /sys to ueventd.

ueventd: parallelize uevent handling
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.

ueventd: Break devices.cpp into discrete classes
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
