[libsigcplusplus/variadic_mem_fun3: 5/148] *mem_functor(): Remove the numbered versions, leaving just variadic ones.

commit 5d8b2cdcd524aed13c133116764e68e7b6c90c62
Author: Murray Cumming <murrayc murrayc com>
Date:   Thu Jan 7 17:14:14 2016 +0100

    *mem_functor(): Remove the numbered versions, leaving just variadic ones.
    
    Do not generate *mem_functor0 through *mem_functor7. Instead just
    generate variadic *mem_functor<>.
    We do still generate mem_functor, const_mem_functor and
    const_volatile_mem_functor, which seems messy.
