- jetlinkd is ancillary: a dead owner sends the drive back to the small
model and no longer blocks engaging
- a crashed owner now restarts, as porting.md asks
- Offroad_JetlinkUnavailable says why a Jetlink the user turned on cannot
run (jetlink's reason())
- JetlinkBigModel, JetlinkCatalog and JetlinkRuntime are no longer used
params_keys.h changed: libparams_c.so, libcommon.a and the prebuilt
manifest need regenerating with the prebuilt build. Until then the
tracked params library does not know Offroad_JetlinkUnavailable, so
hardwared skips that alert (logged once) and it stays inert.
