Change all Unix systems to use stackt for the alternate signal stack (some were using sigaltstackt). Add OS-specific setSignalstackSP function to handle different types for ss_sp field, and unify all OS-specific signalstack functions into one. Unify handling of alternate signal stack in OS-specific minit and sigtrampgo functions via new functions minitSignalstack and setGsignalStack.

(see defs.c and defs1.c) don't work here, so this is yet another
