Joseph Myers 251287734e 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.
