Spencer Nelson 867910ea17 cmd/vet: Use function signature to find format string index.
cmd/vet's printf checker currently uses a hardcoded map of function
names to expected positions of format strings. We can be a bit more
precise than this by looking up the signature of the function, which
helps when libraries implement functions like Errorf or Logf with
extra arguments like log levels or error codes.

Specifically, the format string param is assumed to be the last string
parameter of the called function.

Fixes #12294.

Our canonical Git repository is located at https://go.googlesource.com/go. There is a mirror of the repository at https://github.com/golang/go.

Go is the work of hundreds of contributors. We appreciate your help!

To contribute, please read the contribution guidelines: https://golang.org/doc/contribute.html

Binary Distribution Notes

If you have just untarred a binary Go distribution, you need to set the environment variable $GOROOT to the full path of the go directory (the one containing this file). You can omit the variable if you unpack it into /usr/local/go, or if you rebuild from sources by running all.bash (see doc/install-source.html). You should also add the Go binary directory $GOROOT/bin to your shell's path.

For example, if you extracted the tar file into $HOME/go, you might put the following in your .profile:

export GOROOT=$HOME/go
export PATH=$PATH:$GOROOT/bin

See https://golang.org/doc/install or doc/install.html for more details.
