[OpenBIOS] PATCH: Rework CIF interface to handle parameters in reverse order

Hi all,

This patch is an attempt at reworking the CIF so that it can be called 
correctly from both Fcode (Forth) and C. Currently the C arguments are 
pushed into the stack in reverse order, rather than forward order which 
is required by Forth words calling the CIF.

In order to fix this, we correct the order in which C arguments are 
placed on the Forth stack by pushing the parameters in forward order. 
However, this has the side effect of reversing the order in which the 
parameters to the CIF Forth words are expected and so these must also be 
altered to take this into account.

This patch works as expected from Forth Fcode, but I would like to put 
it out for testing before I commit to the repository. Blue Swirl/Laurent 
- please can you test on your setups again?
