The qos stuff belongs to qtest, so move it into that directory, too.

This removes the hardcoded I2C address from the tests.  The address
is passed via QOSGraphEdgeOptions to i2c_device_create and stored
in the QI2CDevice.

The i2c_send and i2c_recv functions, along with their wrappers,
therefore, can be changed to take a QI2CDevice rather than an
adapter/address pair.

Create an i2c-bus interface, corresponding to the I2CAdapter struct.
Wrap IMXI2C and OMAPI2C with a QOSGraphObject, and add the get_driver
function to retrieve the I2CAdapter.

The conversion is still not complete; for simplicity, i2c_recv and
i2c_send (along with their wrappers) still take an adapter/address
pair.  Fixing that would be complicated until the tests are converted
to qgraph, so it is left for after the conversion.

Provide *_init functions that populate an I2CAdapter struct without
allocating one, and make the existing *_create functions wrap them.

Because in the new setup *_create might return a pointer inside the
IMXI2C or OMAPI2C struct, create companion *_free functions to go
back to the outer pointer.

All this is temporary until allocation will be handled entirely by
qgraph.

The functions to read/write 8-bit or 16-bit registers are the same
in tmp105 and pca9552 tests, and in fact they are a special case of
"read block"/"write block" functionality; read block in turn is used
in ds1338-test.

Move everything inside libqos-test, removing the duplication.  Account
for the small differences by adding to tmp105-test.c the "read register
after writing" behavior that is specific to it.

This is a simple model supporting the basic registers for led and GPIO
mode. The device also supports two blinking rates but not the model
yet.
