wine-crossover: add noconflict variant that doesn't conflict with other wines

[cooljeanius (Eric Gallager)]

Some versions of wine-crossover, such as those bundled by ​WineSkin, prefix all of their files with "cx". I made a variant for the wine-crossover portfile that does the same thing:

variant noconflict description {Removes conflicts with the other Wine ports by adding a prefix to everything installed} {
    conflicts-delete        wine wine-devel
    post-destroot {
        xinstall -d ${destroot}${prefix}/libexec/cxwine
        file rename ${destroot}${prefix}/bin/wineloader ${destroot}${prefix}/libexec/cxwine/cxwine
        file rename ${destroot}${prefix}/lib/libwine.1.0.dylib ${destroot}${prefix}/lib/libcxwine.1.0.dylib
        system -W ${destroot}${prefix}/lib "ln -sfv ./libcxwine.1.0.dylib ./libwine.1.dylib"
        system -W ${destroot}${prefix}/lib "ln -sfv ./libcxwine.1.0.dylib ./libwine.dylib"
        file rename ${destroot}${prefix}/lib/libwine.dylib ${destroot}${prefix}/lib/libcxwine.dylib
        file rename ${destroot}${prefix}/lib/libwine.1.dylib ${destroot}${prefix}/lib/libcxwine.1.dylib
        system "install_name_tool -change @executable_path/../lib/libwine.1.dylib ${prefix}/lib/libcxwine.1.dylib ${destroot}${prefix}/libexec/cxwine/cxwine"

        file rename ${destroot}${prefix}/lib/wine ${destroot}${prefix}/lib/cxwine
        file rename ${destroot}${prefix}/include/wine ${destroot}${prefix}/include/cxwine
        foreach dll [glob ${destroot}${prefix}/lib/cxwine/*.so] {
            system "install_name_tool -change @executable_path/../lib/libwine.1.dylib ${prefix}/lib/libcxwine.1.dylib ${dll}"
        }
        foreach binary [glob ${destroot}${prefix}/bin/*] {
            file rename ${binary} [file dirname ${binary}]/cx[file tail ${binary}]
        }
        system -W ${destroot}${prefix}/bin "ln -sfv ./cxwinegcc ./cxwinecpp"
        system -W ${destroot}${prefix}/bin "ln -sfv ./cxwinegcc ./cxwineg++"
        foreach manpage [glob ${destroot}${prefix}/share/man/man1/*] {
            file rename ${manpage} [file dirname ${manpage}]/cx[file tail ${manpage}]
        }
        file delete ${destroot}${prefix}/share/man/man1/cxwinecpp.1
        file delete ${destroot}${prefix}/share/man/man1/cxwineg++.1
        foreach manpage [glob ${destroot}${prefix}/share/man/*.UTF-8/man1/*] {
            file rename ${manpage} [file dirname ${manpage}]/cx[file tail ${manpage}]
        }

        xinstall ${filespath}/wine.in ${destroot}${prefix}/bin/cxwine
        reinplace s|@PREFIX@|${prefix}|g ${destroot}${prefix}/bin/cxwine

        file rename ${destroot}${prefix}/share/wine ${destroot}${prefix}/share/cxwine
        xinstall -d ${destroot}${prefix}/share/cxwine/gecko

    }
}

I'm only posting this variant here instead of an entire diff or portfile because I made some other extraneous changes to the portfile, too, that I don't want to submit.

I'm not in favor of this being a variant. Either do it all the time, or make it a subport, or don't do it at all. I would be in favor of not doing this at all; the way it is now, wine-crossover acts as a drop-in replacement for wine, which is desirable, isn't it?

[jeremyhu (Jeremy Huddleston Sequoia)]

Yeah, I like these three ports (wine, wine-devel, wine-crossover) being essentially replacements for eachother. Is there a real benefit to having these co-exist?

Same reason WineSkin lets you install multiple versions of Wine: sometimes a program will work with one version of wine but not another.

[jeremyhu (Jeremy Huddleston Sequoia)]

But that's not limited to *just* the three versions we offer. Based on that reasoning, we should offer ports for 1.0.0, 1.0.2, 1.0.3 , ...

But of those, the Crossover version is the only that the prefix gets changed for. Well that and Crossover Games, which gets prefixed with "CXG" instead of just "CX", but wine-crossover-games has been replaced_by wine-crossover for a while now...
