vty api: add vty_out_va()
Provide a va_list type vty_out() variant, to be able to pass on variable arguments from other function signatures to vty_out(). This will be used by Ibd6b1ed7f1bd6e1f2e0fde53352055a4468f23e5 for osmo_tdef. Change-Id: Ie6e6f11a6b794f3cb686350c1ed678e4d5bbbb75changes/73/12773/3
