psi: add support to compute the polygamma function (kth-derivative). * libinterp/corefcn/psi.cc: previously, only the digamma function, k == 0, was being computed. Add support for polygamma function, add tests, and improve documentation. * liboctave/cruft/slatec-fn/dpsifn.f, liboctave/cruft/slatec-fn/psifn.f: the two functions that actually compute the the polygamma functions, copied verbatim from SLATEC, and under public domain. * liboctave/cruft/slatec-fn/module.mk: add dpsifn.f and psifn.f to the build system. * liboctave/numeric/lo-specfun.cc: add new signature for function psi to compute polygamma function that wraps the Fortran DPSIFN and PSIFN functions. * liboctave/numeric/lo-specfun.h: declare new function and document all psi() with doxygen.
