    go/build: replace FindTree, ScanDir, Tree, DirInfo with Import, Package · ebe1664d
    Russ Cox authored
    This is an API change, but one I have been promising would
    happen when it was clear what the go command needed.
    
    This is basically a complete replacement of what used to be here.
    
    build.Tree is gone.
    
    build.DirInfo is expanded and now called build.Package.
    
    build.FindTree is now build.Import(package, srcDir, build.FindOnly).
    The returned *Package contains information that FindTree returned,
    but applicable only to a single package.
    
    build.ScanDir is now build.ImportDir.
    
    build.FindTree+build.ScanDir is now build.Import.
    
    The new Import API allows specifying the source directory,
    in order to resolve local imports (import "./foo") and also allows
    scanning of packages outside of $GOPATH.  They will come back
    with less information in the Package, but they will still work.
    
    The old go/build API exposed both too much and too little.
    This API is much closer to what the go command needs,
    and it works well enough in the other places where it is
    used.  Path is gone, so it can no longer be misused.  (Fixes issue 2749.)
    
    This CL updates clients of go/build other than the go command.
    The go command changes are in a separate CL, to be submitted
    at the same time.
