Restore old pgwin32_message_to_UTF16() behavior outside transactions.
Commit49c817e replaced with a harderror the dubious pg_do_encoding_conversion() behavior when outside atransaction. Reintroduce the historic soft failure locally withinpgwin32_message_to_UTF16(). This fixes errors when writing messages inless-common encodings to the Windows event log or console. Back-patchto 9.4, where the aforementioned commit first appeared.Per bug #13427 from Dmitri Bourlatchkov.
