Rework J1939 and ISO TP feature enablingjellyfish_9.99.4jellyfish_9.99.3jellyfish/9.99.4jellyfish/9.99.39.99.49.99.3
Rework the J1939 and ISO TP feature enabling logic in config.cmake to:
- define WITH_FEATURE_J1939 and WITH_FEATURE_ISOTP to default to off,
thus requiring explicit enabling. This is safer than making
assumptions based solely on the presence of the headers at build
time.
- honor WITH_FEATURE_* definitions given on the cmake command-line;
the checks for header presence only over-ride an "ON" value if the
required header is not present.
