Two Problems
1. Upgrade wizard failed to retrieve path to service executable,
if it contained non-ASCII.
Fixed by setlocale(LC_ALL, "en_US.UTF8"), which was missing in upgrade wizard
2.mysql_upgrade_service only updated (converted to UTF8) the server's sections
leaving client's as-is
Corrected typo.
3. Fixed assertion in my_getopt, turns out to be too strict.
CreateServiceA, OpenServiceA, and couple of other functions do not work
correctly with non-ASCII character, in the special case where application
has defined activeCodePage=UTF8.
Workaround by redefining affected ANSI functions to own wrapper, which
works by converting narrow(ANSI) to wide, then calling wide function.
Deprecate original ANSI service functions, via declspec, so that we can catch
their use.
