b1fa25128a Make it possible to override the Mach fault recovery scheme through an
environment variable: SIGSEGV_MACH_FAULT. It can be set to "direct" to
assume the fault address comes from code[1] argument, or "slow" to use
the slow path through thread_get_status(EXCEPTION_STATE)->faultvaddr.

58ff9aba45 The Linux kernel actually allows to restart execution from the specified slot
in the bundle. This is faster and more accurate as this avoids emulation.

Also clean-up code so that to prepare the use of lib uaccess on hpux/ia64.
XXX: this will need explicit use of uint64_t to define registers because
HP/UX is ILP32 capable and all registers are 64-bit capable so "unsigned long"
won't fit.

57ae6ed470 Add initial support for instruction skipping on Linux/ia64. It was more
complex than expected but it was fun to play with. Who designed this ISA?
I'd love to see how the decoder is implemented in HW, by all means it is
not "simplified" unless I missed some pattern...

9fa1bbd972 According to kernel sources, that is XNU 344.49 (10.2.8), XNU 517.12.7 (10.3.9),
XNU 792.21.3 (10.4.10) and XNU 1228 (10.5.0), exception handler code[1] always
contains the fault address nowadays. So make it the default fast path but keep
provisions to check that at run-time first.

This yields a nearly 4x improvement in SIGSEGV recovery but MacOS X is still
suboptimal wrt. Linux, so VOSF is still not possible with frameskip == 0.

XXX: the ppc kernel had bugs that caused DAR (put into code[1]) to be incorrectly
decoded. This would need a broader test audience or more careful audit of the
sources changes.

9000d4f54c Rewrite ExtFS support for MacOS X. This implementation uses xattrs (metadata)
on Tiger+ to store FInfo and FXInfo. Otherwise, plain old .finfo/ helpers are
used. "Safe" flags and fields are always synchronized to/from MacOS X.

BTW, CFString leak was fixed at the same time.

ab86a395da Since Guest and Host OS may use different text encodings for filenames,
I am adding functionality to support this. For the moment, I've only
added the platform-specific conversion for MacOSX (ie: UTF8 -> MacRoman),
but others can be added later.
