55f5e3a41b Fix CR save/restore in EmulOp thunk. I don't know what it fixes for real
but that was definitely wrong to only preserve CR2 there.

ea42af0568 Consume the packet even if we could not allocate a message block for it in
the Ethernet interrupt. The BeOS version does that, likewise for MOL. Otherwise,
we end up into an infinite loop reporting the memory allocation failure.

I think this is now the expected behavior as we wouldn't have stats
(num_rx_no_mem) for it if we couldn't get out of the EtherIRQ. ;-) Besides,
the packet will be resent for reliable networks.

38d03d02e9 The alternate stack trick never worked as you can't modify an active stack.
i.e. it returned EPERM and ran into stack corruption to eventually crash the
emulator. This is noticeable in !hw_mac_cursor_accl mode (e.g. fullscreen DGA).

In order to the sigalstack() to be effective, we must kludge the kernel to
think it's running on another stack. In practise, we provide another stack
for the SIGUSR2 handler. sigusr2_handler_init() fulfills that purpose.

I hope this fixes remaining issues forever. At some point, I had multiple
*_init() handlers in case this is necessary.

a8ba24aecf Use fast spinlocks only for small enough atomic operations. Otherwise, you
run into some performance problems in e.g. video graphics experience because
of busywaits in the current spin_lock() implementation.

52138d2014 We HAVE_PTHREADS even if we use our own pthreads implementation, this also

gbeauche
26ee263b6f Don't fake the TVECT value on non-BeOS native systems. This is important
for systems that use a global r2 as the TLS register, e.g. Linux/ppc with
newer glibc. Also remove the syscall junk which were simply workarounds
for this bug. Remove a duplicate r2 restoration in EmulOp.

BTW, it's possible to get SheepShaver running on Linux/ppc systems with
NPTL rather than SheepThreads.

0f4440f99f Handle "screen fbdev/WIDTH/HEIGHT" to force use of FBDev DGA instead of XF86
DGA mode. In other words, root user can now use FBDev DGA though it's always
recommended to run SheepShaver with a normal user. Increase "ramsize" bounds
in the GUI and fully migrate to new "screen" modes. Remove "windowmodes" and
"screenmodes" defaults.

d27832cb1c - Implement fullscreen DGA via fbdev access under Linux. Besides, r/w access
to /dev/mem is required on Linux to use XF86 DGA mode. Otherwise, there is
now a fallback to fbdev.
- Forward port some features from Basilisk II (set_window_name,
disable_mouse_accel).
- Don't SIGSTOP the emulation thread on suspend since that would completely
stop the process on Linux. Use a frame buffer lock instead (as B2 does)

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.

Colateral feature: SheepShaver should now run on Linux/ppc64 with relevant
32-bit runtime. Native Linux/ppc64 support is harder as low mem globals are
32-bit in mind and e.g. the TLS register there is %r13, %r2 is the TOC

73d51962f6 Merge in-progress PowerPC "JIT1" engine for AMD64, IA-32, PPC.
The merge probably got wrong as there are some problems probably due to the
experiment begining with CR deferred evaluation. With nbench/ppc, performance
improvement was around 2x. With nbench on x86, performance improvement was
around 4x on average.

Incompatible change: instr_info_t has a new field in the middle. But since
insertion of PPC_I(XXX) identifiers is auto-generated, there is no problem.
