Improve TranslateSocketError() to handle more Windows error codes.
The coverage was rather lean for cases that bind() or listen() mightreturn. Add entries for everything that there's a direct equivalentfor in the set of Unix errnos that elog.c has heard of.

48+
* Note: where there is a direct correspondence between a WSAxxx error code
49+
* and a Berkeley error symbol, this mapping is actually a no-op, because
50+
* in win32.h we redefine the network-related Berkeley error symbols to have
51+
* the values of their WSAxxx counterparts. The point of the switch is
52+
* mostly to translate near-miss error codes into something that's sensible
53+
* in the Berkeley universe.
