Retired *Configure options, and a new header export

Detail:
  * As noted in recent commits to ADFS, the *Configure options Dir and NoDir
    haven't done anything since RISC OS 2, so ADFS has stopped reading the
    CMOS bit. Unusually, these options are implemented by the kernel, so this
    is the accompanying change to remove the *Configure options. This frees
    up a bit of CMOS for future re-use.
  * Now exports a C version of Hdr:ModHand.
Admin:
  Builds OK, but not tested in a ROM build yet (should be fairly safe though)

Version 5.35, 4.79.2.143. Tagged as 'Kernel-5_35-4_79_2_143'
