Use ucontext_t not struct ucontext in linux-unwind.h files. Current glibc no longer gives the ucontext_t type the tag struct ucontext, to conform with POSIX namespace rules. This requires various linux-unwind.h files in libgcc, that were previously using struct ucontext, to be fixed to use ucontext_t instead. This is similar to the removal of the struct siginfo tag from siginfo_t some years ago.
