psi: add support for complex numbers.
* libinterp/corefcn/psi.cc: add logic and input check to support complex
numbers (implementation is in lo-specfun.cc). Add tests.
* liboctave/numeric/lo-specfun.cc, liboctave/numeric/lo-specfun.h: add
template specialization to psi() for std::complex. It is mostly taken from
the implementation in XLiFE++ (also under GPLv3+, see b03c7cccadc2 commit
message for more details).
