gfan shar file

The two ports are related logicaly but there is no dependency between them.

The port math/cddlib is a needed dependency not yet committed to the port tree. You can find it here: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=231161 .

I am porting gfanlib because I am working at porting CoCoA, which has gfanlib as optional dependency.

Corrects first gfanlib shar file by adding missing headers.

I moved the headers from include to include/gfanlib for better compatibility with software such as CoCoALib.

I have done some style corrections based on the suggestions I received on bug #231807.

Log:
  New ports: math/gfan, math/gfanlib

  Gfan is a software package for computing Groebner fans and tropical
  varieties. These are polyhedral fans associated to polynomial ideals.
  The maximal cones of a Groebner fan are in bijection with the marked
  reduced Groebner bases of its defining ideal. The software computes
  all marked reduced Groebner bases of an ideal. Their union is a
  universal Greobner basis. The tropical variety of a polynomial ideal
  is a certain subcomplex of the Groebner fan. Gfan contains algorithms
  for computing this complex for general ideals and specialized
  algorithms for tropical curves, tropical hypersurfaces and tropical
  varieties of prime ideals.  In addition to the above core functions
  the package contains many tools which are useful in the study of
  Groebner bases, initial ideals and tropical geometry.
