[ci skip] Refactor libgd docs

Changes to simplify managing libgd docs a bit:
- Move copyright statement and licensing info to common redistributable
  bins file. All previous notices left intact and updated with the
  upstream info.
- Remove unsynced and difficult to track README file compared to
  upstream README.md file available at https://github.com/libgd/libgd

-This directory contains the GD library available from 
-http://www.boutell.com/gd/
-
-The inclusion of this library with PHP is in response to the 
-popularity of the GD extension and the GD library itself.  We felt
-it would be worthwhile to make sure everyone had access to the
-features of GD and by bundling GD with PHP we have a known target to
-work against.
-
-In addition to the above, a number of motivated PHP hackers have
-expressed an interest in extending the functionality of the PHP-GD
-combination.  By putting a version of GD into PHP CVS we have provided
-a sandbox for them to throw sand at each other in.  Any and all
-improvements we make to the GD library will be contributed back to the
-original maintainers of this library at boutell.com.
-
-The following statement is from the original GD package:
-
-  Credits and license terms
-  
-   In order to resolve any possible confusion regarding the authorship of
-   gd, the following copyright statement covers all of the authors who
-   have required such a statement. _If you are aware of any oversights in
-   this copyright notice, please contact Thomas Boutell who will be
