Title: allocate alternate signal stack, change of sigaction flags for sigterm

Allocate and set stack for SIGSEGV/etc handler (currently NOSTACK was used, but by default alternate stack is not set)
And also don't use nodefer, nostack and resethand for SIGTERM, so receiving second TERM wouldn't kill redis in unclean way.
