Miscellaneous sys/ucontext.h namespace fixes (bug 21457).
This patch fixes various miscellaneous namespace issues in sys/ucontext.h headers. Some struct tags are removed where the structs also have *_t typedef names, while other struct tags without such names are renamed to start __; the changes are noted in NEWS as they can affect C++ name mangling (although there seems to be little if any external use of these types, at least based on checking codesearch.debian.net). For powerpc, pointers to struct pt_regs (not defined in this header) are changed to point to struct __ctx(pt_regs), so in the __USE_MISC case those struct fields continue to point to the existing struct pt_regs type for maximum compatibility, while when that's a namespace issue they point to a struct __pt_regs type which is always an incomplete struct. Tested for affected architectures with build-many-glibcs.py. [BZ #21457] * sysdeps/unix/sysv/linux/m68k/sys/ucontext.h (fpregset_t): Remove struct tag. * sysdeps/unix/sysv/linux/mips/sys/ucontext.h (fpregset_t): Likewise. * sysdeps/unix/sysv/linux/nios2/sys/ucontext.h (mcontext_t): Likewise. * sysdeps/unix/sysv/linux/powerpc/sys/ucontext.h (pt_regs): Declare struct type with __ctx. [__WORDSIZE != 32] (mcontext_t): Use __ctx with pt_regs struct tag. (ucontext_t) [__WORDSIZE == 32]: Use __ctx with pt_regs struct tag and regs field name.
