According to historical device trees, pre-iMac Macs do not seem to
have the /rtas node.
Make /rtas conditional to NewWorld Macs for now, while allowing to
extend this to future CHRP machines.
This means that the ppc-softmmu would by default not have it,
except when using -M mac99. ppc64-softmmu would get it by default.

On ppc64, cell size is 32 bits but pointers are 64-bit.
Thus, direct casts result in warnings, treated as errors.
Use [u]intptr_t cast or cell2pointer and pointer2cell macros as necessary.
v2:
* Drop changes related to physical addresses since physical addresses may be
wider than pointers (e.g., 36 bits on sparc32, as pointed out by Blue).
* Drop changes to cell2pointer() and pointer2cell() for now.

RTAS had to be enabled via EXTRACFLAGS=-DUSE_RTAS.
Use the config file instead.

are not in forth stack order but in reversed (heh!) order. Our implementation
confused this.
This second patch is fairly straightforward; probably the only unexpected part is
the need to rename the existing /openprom/client-services "claim" and
"release" words to "cif-claim" and "cif-release" respectively. This is
because we need to use the "claim" and "release" words in
forth/system/ciface.fs to reverse the argument order before calling the real
underlying words.

The current implementation of the milliseconds prom call on PowerPC is
totally buggy:
- The timer frequency returned by get_timer_freq() does not correspond
to the timer which is read.
- The dividend and the divisor of the division are swapped
- If called very often, this function is not precise
- Depending on the timer frequency and of the frequency of the calls,
the variable overflow after a few dozen of seconds.
Please find in this patch a totally new implementation. This fixes the
problem observed with the quik when a timeout is defined.
The timer frequency is defined using #define, I wonder if there is a
better place to put it.
It reads both low and high part of the timer to make sure there is no
overflow. It also removes the function that returns 0 on the first call
as this is not needed according to IEEE 1275-1994. Finally it computes
the real value of the timer each time, instead of adding a small value
to a variable at each function calls, in order to get a correct
precision if this method is call very often.

This patches copies all needed ppc files to qemu and modifies them.
The generated OpenBIOS image must be loaded at adresse 0xfff00000 by Qemu.
It is able to load Yaboot from disk and Yaboot is able to load Linux, but Linux hangs somewhere... of course it needs more work (but this cleans up my patch queue).
Thank you to Blue Swirl and Aurelien Jarno for their help.
