Distribute the text of ec(3) to the individual EC manuals where it belongs.

Make sure EC_GROUP_new(3) points to all EC manuals and all EC manuals
point back to EC_GROUP_new(3), and add some other useful links as well.
Change all links to ec(3) to point to EC_GROUP_new(3) instead.

+The EC library provides functions for performing operations on

 Within the library there are two forms of elliptic curves that are of
 interest.
 The first form is those defined over the prime field Fp.
