Fixes to get html generation to work

* Rename @anchoridx{Data} to @anchoridx{DateTypes} in section 13 (duplicate
  with the same index in section 7)
* Remove @validatemenus not available after version 6.8 of texinfo
* Rename section "cobc - The GnuCOBOL Compiler - Runtime options" to
  "cobc - The GnuCOBOL Compiler"
* Add @Iftex around menu of section 7.8, as it makes makeinfo segfault and
  is not useful for HTML
* Small additional fixes for info generation to work
