Integrate perlio:

[  9322]
Routine Win32 regen_config_h - no real changes.

[  9321]
PerlIO fixups for Win32:
- provide win33_popenlist() - non-functional as yet.
- avoid need for aTHX in PerlIO_debug calls - even if not 
enabled args are still evaluated so Win32 has trouble during fork().
- Add PerlIO/Scalar to list of extensions in win32/makefile.mk
- Fixup makedef.pl for latest set of symbols.

[  9320]
POSIX::getcwd XS code to call Cwd::cwd when HAS_GETCWD not defined
was gibberish - broke it on WIn32 at least.

[  9319]
Generated files.

[  9318]
Implement:
1.  open($fh,"+<",undef);  # add test to t/io/open.t
2.  open($fh,"+<",\$var);  # New test t/lib/io_scalar.t
