Fix mcontext_t sigcontext namespace (bug 21457).
This patch completes the ucontext.h namespace fixes by fixing issues related to the use of struct sigcontext as mcontext_t, and inclusion of <bits/sigcontext.h> even when struct sigcontext is not so used. Inclusion of <bits/sigcontext.h> by <sys/ucontext.h> is removed; the way to get the sigcontext structure is by including <signal.h> (in a context where __USE_MISC is defined); the sysdeps/generic version of sys/ucontext.h keeps the inclusion by necessity, with a comment about how this is not namespace-clean, but the only configuration that used it, MicroBlaze, gets its own version of the header in this patch. Where mcontext_t was typedefed to struct sigcontext, the contents of struct sigcontext are inserted (with appropriate namespace handling to prefix fields with __ when __USE_MISC is not defined); review should check that this has been done correctly in each case, whether the definition of struct sigcontext comes from glibc headers or from the Linux kernel. This changes C++ name mangling on affected architectures (which do not include x86_64/x86). Tested for x86_64, and with build-many-glibcs.py. 2017-08-14 Joseph Myers <joseph@codesourcery.com> [BZ #21457] * sysdeps/arm/sys/ucontext.h: Do not include <bits/sigcontext.h>. * sysdeps/generic/sys/ucontext.h: Add comment about use of struct sigcontext and namespace requirements. * sysdeps/i386/sys/ucontext.h: Do not include <bits/sigcontext.h>. * sysdeps/m68k/sys/ucontext.h: Likewise. * sysdeps/mips/sys/ucontext.h: Likewise.
