Enable code coverage through the library 'python coverage'. In case the environment variable COVERAGE_PROCESS_START is present (one of the requisites for measuring sub-processes; the second one is including some coverage statements into the python sitecustomize.py file) it will be taken into account, otherwise it is exported with value '.coveragerc'. The latter value is a configuration file (also automatically created) with some default settings. Once tests are executed, a coverage report is shown on the log and the coverage output data is stored with name '.coverage.<args>' where '<args>' is the name of the unit tests executed or 'all_tests' when running with --run-all-tests. This output data can be latter used for better reporting using the same tool (coverage). As briefly indicate before, measuring sub-process implies setting the env variable COVERAGE_PROCESS_START (done automatically by the oe-selftest code with this patch if not already set) and creating a sitecustomize.py as explained on [1]. If either one of these is missing, complete coverage will be incomplete. Current measurements for 'oe-selftest --run-all-tests' indicate that current coverage is around 42 % taking into account BBLAYERS, bitbake and scripts folders. More details on [2], indicating the coverage per file/module.
