Fix net_test_bluetooth

Test: net_test_bluetooth
Change-Id: I8c84f0db3ce0e4f6efbd6d7d3cdc794be8fb7faa

Fix net_test_bluetooth

* net_test_bluetooth should try to load Bluetooth library from
  system/lib/hw or system/lib64/hw if it cannot find it from default
  path
* Also replaced legacy logging macro with libbase logging statements

test_vendor: Add base implementation

test_vendor: Add Device and Beacon classes
Device contains properties to be modeled.  Beacon
is a simple class that inherits from Device.

test_vendor: Add a Device factory
The device factory calls the constructors and initializes
the devices.  The controller uses the factory to instantiate
devices.

test_vendor: Add a Keyboard class
Add a connectable LE device.

test_vendor: Add BrokenAdv device
Generate random broken advertisements.

test_vendor: Add scanning and connections
Add a connection class to handle data transfer.
Add scanning and connections in the controller.

Test: Compiles

Loosen libhardware dependency

In most places we don't really need the libhardware library, just the
headers.

Use one type for UUID (1/5)

Currently, we have few different representations for UUID in stack:
tBT_UUID, tSDP_UUID, bt_uuid_t, bluetooth:UUID, or uint8_t*.

Additionally, tBT_UUID and bt_uuid_t are used to hold UUID as 128bit
as Little Endian or Big Endian, depending on which part of stack (GATT
or SDP) is using it.

This patch is creating one type, bluetooth::Uuid, that will replace all
other types.
