[Ovmsdev] Some warning/error messages

[Stephen Casner]

The reason I encountered this error message was that I had to remove
the SD card in order to test ssh because otherwise there is not enough
free RAM for the connection to open when using v3.0 hardware with the
default configuration.

What the client sees in this case is just that the connection
immediately closes without becoming open first.  Unfortunately, the
error message that appears on the async console is "E (95787) ssh:
Error in reception: -29" which is not very clear.  I could provide the
text corresponding to that error number, but that is "crypto action
failed" which might be misleading.  The problem is that the memory
allocation failure occurs several layers down, so it gets hidden by
higher-level error returns.  I might be able to supply my own malloc
function that logs an error message if the actual malloc fails.

I did go back and reduce the configuration to remove (for now) the
MAX7317, EXT12V, OBD2ECU, RE_TOOLS, EDITOR, CANOPN and the V3 server
and all the vehicles other than null and Roadster.  That allows me to
open an SSH connection with the SD card installed.

My question for you guys is what items that are not part of OVMS could
we safely remove from the default configuration?  Do we need SPIFFS,
MBED_TLS, OPENSSL, PTHREADS?  I'm not sure what libraries are needed
for https.
