App 2.43.5: update checks log what happens

Browse Source 
Each check writes down the networks Android sees, the server's name lookup,
how a failure happened and how many reports wait, and on a failure whether
the internet answers at all, to tell a SIM without data from a server that is
down. The report goes to a USB stick and, once online, the server. No address
or token is written. Tried on the emulator. Not tried on the car.
