Add test coverage and generate report with lcov
Enable coverage with --enable-coverage. "make coverage" will create the report locally, "make coverage-sync" will upload the report to http://www.freedesktop.org/software/systemd/coverage/. Requires lcov version 1.10 to handle naming in systemd and to use the --no-external option. [zj: make the coverage at least generate something with separate build dir, simplify rules a bit: all errors are mine. ]
