pointer to this linked-list of "layers".
It should be noted that because of the double indirection in a C<PerlIO *>,
-a C<< &(perlio->next) >> "is" a C<PerlIO *>, and so to some degree at least
-one layer can use the "standard" API on the next layer down.

A "layer" is composed of two parts:
=item PERLIO_F_CRLF
-Layer is performing Win32-like "\n" => CR,LF for output and CR,LF =>
-"\n" for input. Normally the provided "crlf" layer is the only layer
-that need bother about this. C<PerlIO_binmode()> will mess with this

flag rather than add/remove layers if the C<PERLIO_K_CANCRLF> bit is set
for the layers class.
