    nvmm: Make FPU state more OS-indenpendent
    
    * Introduce an OS-indenpendent 'nvmm_x64_state_fpu' structure, derived
      from NetBSD's current FPU implementation.
    * Also introduce the 'nvmm_x86_xsave' structure, containing the FPU area
      and the XSAVE header.
    * Add the 'nvmm_x86_xsave_size()' that determines the XSAVE area size to
      simplify the code.
    * Rename gfpu -> gxsave, for clarity.
    * Define 'CTASSERT' because 'nvmm.h' and 'nvmm_x86.h' headers will
      be used by libnvmm(3), but <sys/cdefs.h> only defines 'CTASSERT' for
      kernel.
    * Update libnvmm.3 man page accordingly.
