[Patch, quadmath, committed] PR 46817: Add LGPL header to the files in libquadmath/*.[ch]

[Tobias Burnus <burnus at net-b dot de>]

I have committed the attached patch as obvious. Contrary to the source 
files under libquadmath/{math,gdtoa}/, the files libquadmath/*.[ch] did 
not have a copyright header. (Thanks Richard for pointing out.)

The files have been created by FX (and one by me) for GCC; thus, I added 
a LGPLv2.1 header (with FSF as copyright holder).

Committed as Rev. 167521.
