0dcb2b4516 SDL support in SheepShaver too, though it doesn't work in native mode 
on Linux/ppc as libSDL is pulling in libpthread which conflicts with
our sheepthreads.

e0a76f9e38 Don't handle XLM_IRQ_NEST atomically in emulated mode. That's useless since 
this variable is modified only within a single thread and interrupts are
not handled asynchronously.

f2324520b7 Improve timing of periodic threads (from Basilisk II), aka. make 10 seconds 
really last 10 seconds, not 18. ;-)

a533a9c455 Enable DR emulator with OldWorld ROMs too. It turned out that translated 
code was also trying to access Serial memory.

Note however that I noticed some rare crashes with the DR emulator.
Probably caused by nested runs from EmulOps? We'd really want a native
68k emulator too for Execute68k() things.

Also add bus-frequency and timebase-frequency values to the Name Registry.

123a5210e4 Fix nested ppc_interrupt() stack corruption problem by allocating yet 
another stack when next signal is triggered. I am still unsure if
even MacOS would normally handle nested calls to NanoKernel interrupt
routine.

0665ab1139 No need to map ROM executable on emulated/ppc. Make sure to detect unaligned 
EA for lmw/stmw with real addr instead of relying on the signal number.

dd3a208906 Emulated lmw/stmw with unaligned EA. e.g. for BBEdit under MacOS 8.6. 
This may be due to some switch mode that needs to save r13 and upwards.
The faultive code seems to explicitly add 0xee to r1, which causes it to
be unaligned for upcoming lmw/stmw.

e291c6d065 Add fast X11 display locking routines based on spinlocks, or on pthreads 
in the worst case. Optimize out GetScrap() case when we already own the
selection. i.e. make it smoother. Use our own XDisplay{Un,}Lock() routines.

a42281aad1 Implement partial block cache invalidation. Rewrite core cached blocks 
execution loop with a Duff's device. Gather some predecode time statistics.
This shows that only around 2% of total emulation time is spent for
predecoding the instructions.

b8b139faf2 - Share EmulatorData & KernelData struct definitions 
- Introduce new SheepShaver data area for alternate stacks, thunks, etc.
- Experimental asynchronous interrupts handling. This improves performance
  by 30% but some (rare) lockups may occur. To be debugged!

cb1dd6dac5 - Integrate new NativeOp instructions to be used as trampolines to call 
native functions from ppc code.
- Little endian fixes in emul_op.cpp
- Add new 'gpch' 750 patch to workaround crash with MacOS 8.6
- Don't crash in Process Manager on reset/shutdown with MacOS 8.6
- We also have an experimental interrupt thread in emulation mode

9e7670c922 Import VOSF from Basilisk II for faster and more accurate video refresh. 
There may be some bugs left though. Rework sigsegv_handler() a little to
accomodate VOSF way of life.
