configure: print proper message for test releases

* configure.ac: If the current release is detected to be a test
release or a development snapshot, print a proper warning for
the user.
* README-alpha: Delete, it's obsolete now (and in fact this file
hasn't been touched in eleven years, since release 1.4b or so).
* HACKING (Release procedure): Don't say to update README-alpha.
