Use __glibc_reserved convention in mcontext, sigcontext (bug 21457).
This patch implements the most straightforward part of fixing namespace issues for sys/ucontext.h and related headers: where fields in sys/ucontext.h or bits/sigcontext.h are named "reserved", "padding" or similar, they are renamed to use the __glibc_reserved* naming convention. It does not change fields with a leading underscore, or even those with a prefix such as uc_ or sc_. It only fixes a small part of bug 21457, so no XFAILs are removed. Tested for x86_64 and x86, and with build-many-glibcs.py. [BZ #21457] * sysdeps/unix/sysv/linux/mips/sys/ucontext.h [_MIPS_SIM != _ABIO32] (mcontext_t): Rename field reserved to __glibc_reserved1. * sysdeps/unix/sysv/linux/x86/bits/sigcontext.h (struct _fpx_sw_bytes): Rename field padding to __glibc_reserved1. (struct _fpxreg): Likewise. [!__x86_64__] (struct _fpstate): Rename field reserved to __glibc_reserved1. Rename field padding to __glibc_reserved2. [__x86_64__] (struct _fpstate): Rename field padding to __glibc_reserved1. (struct _xsave_hdr): Rename field reserved1 to __glibc_reserved1. Rename field reserved2 to __glibc_reserved2. * sysdeps/unix/sysv/linux/x86/sys/ucontext.h [__x86_64__] (struct _libc_fpxreg): Rename field padding to __glibc_reserved1. [__x86_64__] (struct _libc_fpstate): Rename field padding to __glibc_reserved1.
