Export fast *rint* functions

[Dave Korn]

    Hi gang,
 
  This patch exports all the new _f_*rint* functions from newlib, adds aliases for
the non-_f_* names, and redirects the exports for the existing functions
(rint/rintf/lrint/lrintf) away from the current slow soft float implementation and
toward the _f_ versions.  The slow soft float implementation is still linked
internally in the dll against some functions such as nearbyint(), pow(), powf(), and
a few others.

  As far as I can see, there's no reason not to get rid of the old slow soft-float
implementations altogether, and that will be the subject of a follow-on patch to
newlib, but it'll have to wait for Jeff to get back from holiday now.

  Oh, and Happy Christmas! to the MPlayer and ffmpeg teams :)
