split "mandatory" field into "recognition-mandatory" and "presence-mandatory"

};
};
=== Loader Config Keys ===
=== Loader Config Keys ===
A loader key can be mandatory or not mandatory.
A loader key can be marked as recognition-mandatory or not recognition-mandatory in its <code>Flags</code> field.
The presence-mandatory field is part of the specification and does not go in the <code>Flags</code> field, but any complying loader must pass all fields specified to be presence-mandatory.
If an (at the time) mandatory unknown key is encountered, the program should jump to [[#LoaderReturnAddr]] with <code>result_code=346 | ((100 + key) << 9);</code>.
If a key is marked as recognition-mandatory and is not recognized by the application, the program should jump to [[#LoaderReturnAddr]] with <code>result_code=346 | ((100 + key) << 9);</code>, as the default behaviour may be unsafe.
If a key that is mandatory is not found (for example with an outdated loader), use <code>result_code=346 | ((200 + key) << 9);</code>.
If a key that is presence-mandatory is not found (for example with an outdated loader), use <code>result_code=346 | ((200 + key) << 9);</code>.
