A large refactoring, but no behavior change;

replace all relevant ascii strxxx fn's with _tcsxxx macros and encode relevant text
with the _T() macro wrapper, permitting /D UNICODE builds in place of /D _MCBS
builds in use today.  This allows for internationalized unicode service names and
textual modification.  Since this is win32 only, using APR style utf-8-ization is silly.

Because today this module simply isn't loadable on Win95-ME, nobody has actually
complained, and we really have no desire to support such a dangerous OS in the
wild of the internet, the unicode build should become the default.
