abort2: Generate a core dump
Call sigexit rather than exit1 so that a core is generated. If running the SIGABRT handler is desired, this would need to use kern_psignal() instead. In that case a userspace wrapper in libc would be needed to force an exit if the handler doesn't exit. Given that abort2(2)'s intended use case is when userland is in a sufficiently bad state such that it can't safely call syslog(3) before abort(3), a userspace abort2(3) wrapper in libc might be dubious.
