Apparently, people can be mislead by these ancient papers that no longer
represent the direction that we want to take in terms of GDB development,
so Daniel suggested that we remove them.

Attached is a patch that removes the links to the papers on libgdb.
We can also delete papers/libgdb and papers/libgdb2 which are the
papers themselves.

(note that papers/index.html seems to be orphaned)

  * documentation/index.html: Remove a reference to a libgdb paper.
  * papers/index.html: Remove references to both libgdb papers.
  * papers/libgdb: Delete this directory.
  * papers/libgdb2: Delete this directory.

Any objection?

PS: I made a change to documentation/index.html just earlier today,
    so the last-changed date does not change.
