func TrimmedCommandOutput

func TrimmedCommandOutput(ctx context.Context, commandName string, args ...string) (string, error)

TrimmedCommandOutput runs a command and returns its combined stdout and stdrerr (whitespace-trimmed), timing out after a period prescribed by commandTimeout. If the command returns a non-zero exit code, returned error is an exec.ExitError.

idevice commands tend to return everything--both errors and normal output--on stderr. However, they don't advertise that as part of their contract, so we take both stdout and stderr for durability.
