Make autodie's open honor the open pragma.

* This uses undocumented keys in the hint hash
* This does not work before 5.10 because you can't get at the hint hash
* This does not take into account the lexical leak guard wrapper
* sysopen might need it too, need to check
Add support for sysopen and read/write filehandles.
