Russ Cox 9ad2319bbc cmd/buildid: add new tool factoring out code needed by go command ... This CL does a few things. 1. It moves the existing "read a build ID" code out of the go command and into cmd/internal/buildid. 2. It adds new code there to "write a build ID". 3. It adds better tests. 4. It encapsulates cmd/internal/buildid into a new standalone program "go tool buildid". The go command is going to use the new "write a build ID" functionality in a future CL. Adding the separate "go tool buildid" gives "go build -x" a printable command to explain what it is doing in that new step. (This is similar to the go command printing "go tool pack" commands equivalent to the actions it is taking, even though it's not invoking pack directly.) Keeping go build -x honest means that other build systems can potentially keep up with the go command.
