Modified Files:
	src/sbbs3/js_global.c main.cpp services.c src/xpdev/ini_file.c multisock.c sockwrap.c sockwrap.h
Log Message:
Make socket errno and string descriptions easier to get/use

Add/use SOCKET_STRERROR which gets the description of the *last* socket
error.

We should start using socket_errno(true) in place of ERROR_VALUE (horribly
named macro) for comparing last socket error nubers against values/macros
from errno.h.

Eliminate get_socket_errno(), unused and redundant with socket_errno().
