It implements all the bits needed to do image activation, signal handling, stack management and threading. This allows us to get to the "Hello World" level. The arm and x86 code are now the same as in the bsd-user fork. For full context, the fork is at https://github.com/qemu-bsd-user/qemu-bsd-user/tree/blitz (though the the recent sig{bus,segv} needed updates are incomplete). v5 changes: o Moved to using the CPUArchState typedef and move set_sigtramp_args, get_mcontext, set_mcontext, and get_ucontext_sigreturn prototypes to bsd-user/freebsd/target_os_ucontext.h o Fix issues with arm's set_mcontext related to masking and remove an unnecessary check. We're down to only one hunk needing review: bsd-user/arm/target_arch_signal.c: arm set_mcontext Warnings that should be ignored: o make checkpatch has a couple of complaints about the comments for the signal trampoline, since it's a false positive IMHO.
