pgbouncer - pgbouncer: win32: simpler service handling, cleanups - one

Log Message:
-----------
win32: simpler service handling, cleanups

- one pgbouncer instance per service, in-process
- read service name from config file

cleanups:

- use FormatMessage for strerror()
- error out on wide-char build
- tag stdout/err _IONBF, they seem fully buffered by default
