examples: Remove heap allocation from C++ examples
Cleanup of UPM C++ examples. Switched from heap allocation to stack allocation when possible. This simplifies the samples since it removes the need for explicit memory management. A script was used to identify and replace pointer use. To simplify the replace script, I re-formatted the C++ examples using the UPM .clang-format file. Unfortuantely this changes the look of the UPM C++ examples to a large degree. However, examples will now have a standard look/feel and uniform formatting. * Ran clang-format w/provided UPM .clang-format file * Removed new's/delete's whenever possible (left those in interface examples) * Added IIO sensor library implementation of callback void* arg * Converted all sleeps to upm defined delays (added header when necessary) * Scrubbed CXX example includes Signed-off-by: Noel Eck <noel.eck@intel.com>
