auto merge of rust-lang#434 : alexcrichton/cargo/issue-433, r=huonw
All subprocesses will now be invoked with CARGO_MANIFEST_DIR pointing at the root of the source directory that they are working on (compiling). This commit also reorganizes the version environment variables to use the new infrastructure. Closes rust-lang#433
