Fix escaping issues in open-process on Windows.

This can now execute programs with spaces in their path names.
Arguments can contain embedded double quotes, and other characters
that are special to cmd.exe, like &, |, (, ), ^ and others.

* stream.c (string_extend_count, win_escape_cmd): New static functions.
(win_escape_arg): Fix and extend escaping scheme to cover not only
the argument processing scheme implemented by programs which use Microsoft's
C library, but also to smuggle the command line through cmd.exe.
(win_make_cmdline): Use win_escape_cmd to wrap the command.
Escape the quotes which are placed around arguments, so cmd.exe
doesn't interpret them, which will cause it to suppress its processing
of the caret escapes.
