Add complex erf,erfc,erfcx,erfi,dawson routines from Faddeeva package.
* libinterp/corefcn/mappers.cc: Add erfi and dawson mapper functions,
and add complex-argument test cases for erf, erfc, erfcx, erfi, and
dawson.
* libinterp/octave-value/ov-base.cc, libinterp/octave-value/ov-base.h:
Add erfi and dawson mapper functions.
* libinterp/octave-value/ov-complex.cc, libinterp/octave-value/ov-cx-mat.cc,
libinterp/octave-value/ov-cx-sparse.cc, libinterp/octave-value/ov-float.cc,
libinterp/octave-value/ov-flt-complex.cc,
libinterp/octave-value/ov-flt-cx-mat.cc,
libinterp/octave-value/ov-flt-re-mat.cc,
libinterp/octave-value/ov-re-mat.c,
libinterp/octave-value/ov-re-sparse.cc,
libinterp/octave-value/ov-scalar.cc,
libinterp/octave-value/ov.h:
Support erf, erfc, erfcx, erfi, and dawson mapper functions for
real and complex matrices and scalars.
* liboctave/cruft/Faddeeva/Faddeeva.cc, liboctave/cruft/Faddeeva/Faddeeva.hh:
liboctave/cruft/Faddeeva/module.mk, liboctave/cruft/Makefile.am:
Add Faddeeva package (from http://ab-initio.mit.edu/Faddeeva) to
libcruft, to provide the various complex-argument error functions.
* liboctave/numeric/lo-specfun.cc, liboctave/numeric/lo-specfun.h:
Add complex-argument erf, erfc, erfcx, erfi, and dawson functions
to liboctave API. Delete previous real-argument erfcx implementation
in favor of Faddeeva::erfcx (which seems to be slightly faster
in gcc/x86-64 benchmarks, with similar accuracy).
* doc/interpreter/arith.txi: Include erfi and dawson documentation.
