A lot of code touched because low level functions needed to pass up
error messages reliably, and this had to propagate up the entire
driver hierarchy.
Tested OK *in English* on:
> Linux
> OSX 10.10.x
> Windows VS2017
> Windows mingw64
I have no way to test on Android, but it might work.
TODO: Needs testing in other languages to verify proper UTF8 error messages,
esp. with Windows VS, due to complexities with FormatMessage() -- see get_ms_errmsg()
