Rename struct ucontext tag (bug 21457).
The ucontext_t type has a tag struct ucontext. As with previous such issues for siginfo_t and stack_t, this tag is not permitted by POSIX (is not in a reserved namespace), and so namespace conformance means breaking C++ name mangling for this type. In this case, the type does need to have some tag rather than just a typedef name, because it includes a pointer to itself. This patch uses struct ucontext_t as the new tag, so the type is mangled as ucontext_t (the POSIX *_t reservation applies in all namespaces, not just the namespace of ordinary identifiers). Another reserved name such as struct __ucontext could of course be used. Because of other namespace issues, this patch does not by itself fix bug 21457 or allow any XFAILs to be removed. Tested for x86_64, and with build-many-glibcs.py.
