Integrate perlio:
Jarkko Hietaniemi [Fri, 17 May 2002 19:13:18 +0000 (19:13 +0000)]
[ 16657]
Fix the crlf.t buffer leak
- actually a generic PerlIOBuf_xxx derived leak-on-pop, but :crlf
flagged it because it is more often popped without stream
being closed.
- Define non-noop PerlIOBuf_popped(), use it and export it.
