Merge Carp::Heavy into Carp

I've reported the issue in
https://rt.cpan.org/Ticket/Display.html?id=49617

Sorry for the delay, apparently I forgot to inform p5p about it at that
time.

Another victim is Test::Warn 0.21. The number of dependencies on these
two modules is huge, CPANTS says >600, http://ali.as/top100/ volatile
100 list scores them together with >3300 points.

I'm not sure why Carp::Heavy should go, maybe it is not worth breaking
such a large portion of CPAN?

The thread that led to it is here:

http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2009-06/msg00978.html

The bug report (#42329) is older.

The gist of the bug is that the old structure of Carp/Carp::Heavy meant that
when an error occurred, Carp would need to use *more* resources to report the
error, and if the resource allocation failed, then Carp would fail to report
the error. This is extremely undesirable.

So, yes, sadly, it is a necessary fix.

That leaves 2 modules on CPAN that need adapting. Although it's unclear to
me why they are sensitive to the internals of Carp.

That was the first question that came to my mind.

Me too, a superficiail review shows nothing obvious at all.
