Time to clean up (or throw out) some of the things I've been sitting on
for a while.  First off, the idea of only changing the OS version in a
single file.  Last I mentioned this, Chris Demetriou had some useful
input in cleaning up the script.  Perry had an objection:

We've never used those last two digits - is it likely that we ever will?

I've been using the following without problems since early May...  As I
said, time to bin it or keep it.  Opinions?


Here's what __NetBSD_Version__ would be defined as:

 *      #define __NetBSD_Version__ MMmmrrppRl
 *
 *      M = major version
 *      m = minor version
 *      r = release ["",A-Z but numeric]
 *      p = patchlevel
 *      R = release status (0 pre release, 1 released)
 *      l = (pre)release level (1 for alpha, 2 for beta, ...)
 *
 *      So:
 *           NetBSD-1.2D       = 102040000
 *      And:
 *           NetBSD-1.2.1_BETA = 102000102
 *      And:
 *           NetBSD-1.2.1      = 102000110

and here's the new osrelease.sh:
