VMInterface addition: Make native library names part of VMInterface

[Dalibor Topic]

Hi all,

One of the things I keep stumbling over whenever I merge code from 
Classpath into Kaffe is the different native library names. Would it be 
possible to separate those out into their own VMInterface class and use 
references instead?

I'd prefer something like

System.loadLibrary(VMNativeLibraries.IO);

to what we have now,

System.loadLibrary("javaio");

where library names are hardcoded in each class that needs to use them. 
Beside preventing errors the compiler can't catch, like misspelling a 
library name, it would make the code slightly cleaner in my opinion, as 
it would replace a hardcoded constant with a single occurence. If 
everyone agrees, I'd be happy to provide a patch, and an implementation 
of the VMNativeLibraries class with the current library names.

cheers,
