This adds some extra instrumentation to bessel_j0.hpp, everything else are fixes for the test programs.
The advantage of testing on this platform is that it has a true 128-bit long double which is a good test of our assumptions in code.
Add some extra jacobi, hankel and owens_t tests and fix resulting errors.
Allow remez code to work with expression template types.
Regenerate docs.
