    x86/fpu: Rename copyin_to_xsaves()/copyout_from_xsaves() to copy_user_to_xstate()/copy_xstate_to_user()
    
    The 'copyin/copyout' nomenclature needlessly departs from what the modern FPU code
    uses, which is:
    
     copy_fpregs_to_fpstate()
     copy_fpstate_to_sigframe()
     copy_fregs_to_user()
     copy_fxregs_to_kernel()
     copy_fxregs_to_user()
     copy_kernel_to_fpregs()
     copy_kernel_to_fregs()
     copy_kernel_to_fxregs()
     copy_kernel_to_xregs()
     copy_user_to_fregs()
     copy_user_to_fxregs()
     copy_user_to_xregs()
     copy_xregs_to_kernel()
     copy_xregs_to_user()
    
    I.e. according to this pattern, the following rename should be done:
    
      copyin_to_xsaves()    -> copy_user_to_xstate()
      copyout_from_xsaves() -> copy_xstate_to_user()
    
    or, if we want to be pedantic, denote that that the user-space format is ptrace:
    
      copyin_to_xsaves()    -> copy_user_ptrace_to_xstate()
      copyout_from_xsaves() -> copy_xstate_to_user_ptrace()
    
    But I'd suggest the shorter, non-pedantic name.
