Log Message:
Sync all resumecontext.c versions with the changes originally made
by Matthias Drochner to i386 and alpha:

-check for a NULL uc_link before calling setcontext(2); do a real exit(3)
 instead with exit handlers and all that
-If setcontext(2) returns (which it shouldn't), do an _exit(-1) rather
 than relying on a sensible return value to use as exit code. Makes
 it less likely that an ucontext corruption goes unnoticed.
