#7867: Need to provide all CPU registers to signal handler

Comment (by bonefish):
Just extending the `vregs` structure will break binary compatibility
(there's the `_reserved_1` which can and should be used, but obviously
that isn't enough). You'll also have to introduce a binary compatible
version of the structure (`vregs_beos`) and adjust the
x86_signal_frame_function_beos() function (cf.
src/system/kernel/arch/x86/x86_signals_asm.S, and
src/system/kernel/arch/x86/asm_offsets.cpp for the assembly offset/size
macros).
