clean up logging, and add error reports to it too

The SSRF_INFO() macro is widely used, and there's a lot of confusion
about whether the newline at the end should be done by the SSRF_INFO or
be in the format string passed to it.  End result: we end up doing both,
and there are empty lines in the output as a result.

Clean this up by just using our existing 'strip_mb()' to strip any
whitespace at the end of the generated string, and then adding one final
newline when logging it.

Also, make sure to log our 'report_error()' messages, which apparently
only used to be showin in the red error bar on the display.
