757f849ad0 Optimize generated code to NQD & CheckLoad functions. They don't call into 
68k or MacOS code, so they don't need to be a termination point. i.e. don't
split into two basic blocks and thus avoid a full hash search.

Also add missing NQD_unknown_hook NativeOp from previous commit.

21f35a34f0 Add patches for native GetNamedResource() and Get1NamedResource(). This will 
be useful to fix a bug in the AppleShare extension (see DRVR .AFPTranslator
in Basilisk II)

Unrelated improvement: call sheepshaver_cpu::get_resource() directly, don't
get it through another global function.

f32e053178 Apply the no-stack-frame optimization in op_invoke_*() to MacOS X for Intel 
templates. This avoids mis-aligninment of the stack, and useless reservation
of space on it for function args. Indeed, we now pre-allocate 16 stack-slots
in op_execute() for this purpose.

6eacaf2e82 Fix asm clobbers for newer gcc 4.0.1, don't use -msse to enable xmm clobbers 
(likewise for -mmmx vs. mmx registers). Instead, since GCC won't generate
MMX/SSE code without explicit intrinsics use of vectorization, we know
those register won't be clobbered outside of the __asm__ code. So, it's safe
as is (we could also remove all sse/mmx clobbers).

97726bd1e7 Minor tweaks to support compilation of ether.cpp within MacOS. i.e. mostly 
migrate the Ethernet driver to the MacOS side. This is enabled for
DIRECT_ADDRESSING cases. I didn't want to alter much of ether.cpp (as it
would have required to support that mode). Of course, in REAL_ADDRESSING
mode (the default) and for debugging purposes, the old driver is still
available.

ec8661f431 Fix a damn silly bug. On some occasions, we could have spcflags() set to 
EXEC_RETURN | HANDLE_INTERRUPT. And then, we handled the interrupt, but
EXEC_RETURN was set so we returned very quickly without completing the
interrupt routine. As a side effect, this occasionnaly hung the emulator
most likely with {ethernet,audio}-based applications that trigger a lot
of interrupts.

The fix is to always honour EXEC_RETURN flag at first, of course.

08c5f8b713 Improve idle wait mechanism. Now, the emulator thread can be suspended

a thread wait/signal mechanism.

0db0d48bf0 Avoid the use of floating-point when loading/storing from/to memory. This 
could have caused some rounding thus alterations to integer registers on
context switches when lfd/stfd instructions were used. e.g. cygwin compilers
defaulted to i686 code generation and exhibed this behaviour, you could also
see this behavior with -march=i586 -mtune=pentiumpro. GCC is perfectly right
to do those optimizations.

of supposing it to be (BusClockSpeed/4), which is no longer true on G5 et al.

3e5c98c7d4 Performance of VOSF is heuristically determined at run-time, so have to 
initialize SIGSEGV handlers early, as in Basilisk II. Besides, also add
missing call to vm_init() in case host system doesn't have MAP_ANON.

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.

301d3a3192 STATS: Account for all interrupts, but still count native interrupts. It 
turns out that for a regular bootup sequence to the Finder, less than 30%
interrupts triggered were in native mode.

Default EMUL_TIME_STATS to 0, end user probably doesn't want garbage to
be printed to his console.
