remove _Bessel functions

As per #16023 comment 8. kcrisman writes:

The Bessel functions weren't removed that long ago, and note that there is a LOT more to be removed - namely, the whole underscore versions of them, see https://github.com/sagemath/sagetrac-mirror/blob/develop/src/sage/functions/bessel.py?id=9db8c5c598ec9de953a33b14e531bee3c092c199#n1102 - basically to the end of the document.

This was originally deprecated in #4102, I believe; if we give it a year, which seems the least one could do here, looks like sometime late summer 2014 should be a good time to do this.

Was merged into #16737, so it's a duplicate now.
