    Bug 21053: sh: Reduce namespace pollution from sys/ucontext.h
    
    The problem is basically that sys/ucontext.h is defining R0..R15
    which happens to conflict with some packages like Firefox when
    trying to build on SH.
    
    The very same problem existed on arm back then [1] and it was fixed by
    renaming R0..R15 to REG_R0..REG_R15.  This patch imploy a similar
    strategy for SH.
    
    Checked on sh4-linux-gnu with run-built-tests=no and I also got reports
    that it fixes Firefox build on Debian sh4.
    
    	* sysdeps/unix/sysv/linux/sh/sh3/ucontext_i.sym: Use new REG_R*
    	constants instead of the old R* ones.
    	* sysdeps/unix/sysv/linux/sh/sh4/ucontext_i.sym: Likewise.
    	* sysdeps/unix/sysv/linux/sh/sys/ucontext.h (NGPREG): Rename...
    	(NGREG): ... to this, to fit in with other architectures.
    	(gpregset_t): Use new NGREG macro.
    	[__USE_GNU]: Remove condition; all architectures other than tile
    	are unconditional.
    	(R*): Rename to REG_R*.
