examples: C/C++ examples use transitive dependencies
Updated the examples to comprehend transitive dependencies. This means
that each example target will no longer have a giant list of -I includes
(the examples at the end of the list had includes for all previous
examples, upwards of 200 -I's on the command line).
* Created a CMakeLists.txt in the upm/examples directory, moved
common functionality to this level.
* C/C++ examples now look to the filename for their dependency
target name, ie; gas-mq2.cxx adds a dependency to the 'gas' target
* Updated a handful of C/C++ example names to reflect this
* Example CMake flow - glob the list of files, add targets for any
special case examples, then att targets for all the rest
