use it. It is not (yet) included in the build and won't break anything. As we now only have thin wrappers around the *Data() functions, the templatized implementation does not make much sense anymore and wouldn't work either. I started this new implementation to be as clean as possible. Instead of using a std::map and BDataBuffer it uses BList and BMallocIO. It passes the unit tests and it even seems to be a bit quicker in some tests (but not as quick as the R5 one). Flattening/Unflattening does not work yet so you can't use it under Haiku right now. It's completely work in progress (I started it just 4 hours ago). Shout if you see something completely broken, reviews welcome. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@13776 a95241bf-73f2-0310-859d-f6bbb57e9c96
