[rfc/rfa(DavidT?)] Move DOUBLEST to doublest.{h,c}

[Andrew Cagney <ac131313@cygnus.com>]

Hello,

(As they say, always have a plan B.  Plan A, reclaim floatformat, failed 
:-).

The attached patch moves all the floating point conversion routines to a 
single place - doublest.[hc].  It doesn't modify the actual code.  It 
updates all the missing include dependencies that I could find.  All the 
  buildable targets listed in the MAINTAINERS file still build.

Look OK?  I note this carves a chunk out of both utils.c and findvar.c

What's next?

I've a follow on patch to introduce two new functions 
extract_floatformat() and store_floatformat().  All th magic currently 
found in extract_floating() and store_floating() would be moved to these 
new functions.  All current calls to floatformat_from_doublest() and 
floatformat_to_doublest() would be replaced by those functions.  The net 
effect would be that all floating point conversions would go through a 
single path and always use the most exact mechanism available.

I've also a second patch to tweek the actual conversion code so that it 
isn't as lossy (use ULONGEST instead of unsigned long).

If anyone ever gets inspired they could then extend doublest.[hc] to 
implement portable floating point (using either gcc/real.c or 
sim/common/sim-fpu.[hc].

Yes looks good (anyone can change the NEWS file).
