Repaces them with just doing the error check,
and a loop for available characteristic keys.

As part of this, refactored characteristic initialization into its own
function so it can be used by both templates and static info.

Fills in initial values for all required static info
fields for LIMITED devices. Currently fakes entries
that will eventually be queried from the device (open
bug https://b/29394024).

Since V4L2CameraHAL now populates its list of cameras,
also added a necessary piece of metadata that was
causing cameraservice to crash.
BUG: 29160300
TEST: Ran on rpi3. HAL finds dev/video* nodes. When a
sym link (/dev/video5 -> /dev/video0) was added, the HAL
correctly did not add a 3rd device.

Decent outline of an initial HALv3. Still a lot to be filled in.
Adapted from the reference implementation in libhardware.
BUG: 29006356
TEST: Ran simple test program. Connects to the HAL and then
fails because there are no cameras (expected behavior right now).
