nan: Relicense under LGPLv2+

nan: Relicense under LGPLv2+

[Bruno Haible]

The module 'nan' (previously tests/nan.h, now lib/nan.h) defines functions
for getting a NaN value reliably. This module is, so far, under GPL,
because historically only the tests use it.

I would like to use it under LGPLv2+, for the modules 'setpayload*'
and 'getpayloadl' (functions defined by ISO C 23 and implemented in glibc).

Can I have your agreement to relicensing your contributions to this
module under LGPLv2+, please?

Yes, I have no problems with my contributions being LGPLv2+ on this
module.

Thanks to you all for approving it. (Daniel Richard G.'s approval reached me
by private email.)

With this, we can relicense 'nan' under LGPLv2+.

And 'signed-nan' as well, to which I am the only relevant contributor.

And 'snan' as well, to which I am the only relevant contributor. (The
contribution by Ulrich Weigand to test-isnanl.h [1] is not relevant per [2].)

And 'signed-snan' as well, to which I am the only relevant contributor.
