fftw's library name depends on the precision option. Consequently,
it's possible to install multiple flavor on the same target.
This patch breaks fftw quad precision into a new package and:
- makes BR2_PACKAGE_FFTW_PRECISION_QUAD select BR2_PACKAGE_FFTW_QUAD
to keep compatibility with packages that use
BR2_PACKAGE_FFTW_PRECISION_QUAD. This option will be removed in a
follow-up commit;
- makes fftw depend on fftw-quad when this package is enabled.

[Yann/Thomas:
- Force --disable-quad in FFTW_CONF_OPTS, just for the sake of
clarity (fftw is no longer going to build the quad variant)
- Use FFTW_QUAD_DL_SUBDIR to avoid downloading fftw multiple times
- Minor reformatting tweaks in fftw-quad.mk
- Do not deprecate BR2_PACKAGE_FFTW_PRECISION_QUAD and instead
make it select BR2_PACKAGE_FFTW_QUAD, so that packages using
BR2_PACKAGE_FFTW_PRECISION_QUAD continue to work.]
