Merge gdtoa-20110304.

Import gdtoa sources dated 2011-03-04. This version includes a number
of bugfixes, although I believe we already have local patches for the
ones people are likely to notice.

Per a request from arundel@, I also added the vendor's change log,
which is available separately from ftp://ftp.netlib.org/fp/.
