Remove unused variables throughout the code base and enable the
`-Wunused-variable` warning flag globally to prevent new unused

of the clGetDeviceInfo return value was added.

Fix various memory leaks around events.
Convert test to use supplied typewrappers
to avoid memory leaks. Also use error helper
functions to reduce code size.
Use stringstreams to synthesize kernel sources, and
raw c+11 string literals.
