[perl #116467] Pod::Checker should be switched to use Pod::Simple

A few months ago, I posted a notice about some of this work:

http://markmail.org/thread/wwuo7gkjbaef6y6s

The biggest problem right now is that the Pod::Checker code is "acting weird" with the "garbled 
E<>" tests.  I'm not sure exactly what's going on, but I have a sneaking suspicion that if it's 
addressed, everything else will fall in line.

I have pushed a lousy "shove all Marc's work into the dist" here:

https://github.com/rjbs/Pod-Checker/commits/pod-simple-checker

Once that's done, the next steps are to release it to CPAN and to bring it into a branch in core.  
That will immediately fail all tests, but Marc's work (with some work from Karl) pointed at by 
previous commentary in this ticket is meant to deal with all those problems.

I expect there will be some bitrot! :-(

We'll need to get porting/podcheck.t passing with the new Pod-Checker before it can be cored.  
This is likely to be something to land immediately on 5.19.0, rather than 5.17.10, but I guess 
we'll see how quickly somebody can get this fixed.
