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.
