I did today an initial code for basic NatFeats support:
It implements the basic id/call and name/version/stderr/shutdown
functionalities and there's --natfeats command line option &
bNatFeats configuration file option to enable/disable it.
I've modeled it on how it works in Aranym. I'm not sure whether
the status register stuff is needed, but as it was used in Aranym,
I added it here also.
It doesn't yet raise bus error / priviledge exception in case
the arguments or supervisor mode isn't correct. How I can invoke
those in Hatari?
(Some review on code in general wouldn't be bad either.)

Aranym's clipboard NatFeat could be useful too.

Current option is bool, it can be changed later on to take a list
of values like --trace, if more features get added to it.
The "name" Native Feature function is now the long asked way for
code to know that it's running under Hatari. User just needs to
use "--natfeats yes" for that detection to work. ;-))
