Log Message:
sbbs3,xpdev: enlarge socket-error message buffers from 128 to 256

On Windows, FormatMessageA() inside socket_strerror() can produce
descriptions longer than 128 bytes for some WSA errors. WSAESHUTDOWN's localized text is ~135 bytes ("A request to send or receive data was
disallowed because the socket had already been shut down in that
direction with a previous shutdown call."). When the buffer is too
small, FormatMessageA fails with ERROR_INSUFFICIENT_BUFFER and the
caller sees the fallback "Error 122 getting error description" instead
of the real message.

Bump the seven remaining call sites that still passed [128] to
SOCKET_STRERROR (main.cpp output_thread, services.cpp x3, multisock.c
x2, ini_file.c) up to [256], matching services.cpp's other buffers
(error[256] at lines 283 and 1940).
