maint: Move non-dynamically linked functions from DLD-FUNCTIONS/ to corefcn/ directory * __contourc__.cc, __dispatch__.cc, __lin_interpn__.cc, __pchip_deriv__.cc, __qp__.cc, balance.cc, besselj.cc, betainc.cc, bsxfun.cc, cellfun.cc, colloc.cc, conv2.cc, daspk.cc, dasrt.cc, dassl.cc, det.cc, dlmread.cc, dot.cc, eig.cc, fft.cc, fft2.cc, fftn.cc, filter.cc, find.cc, gammainc.cc, gcd.cc, getgrent.cc, getpwent.cc, getrusage.cc, givens.cc, hess.cc, hex2num.cc, inv.cc, kron.cc, lookup.cc, lsode.cc, lu.cc, luinc.cc, matrix_type.cc, max.cc, md5sum.cc, mgorth.cc, nproc.cc, pinv.cc, quad.cc, quadcc.cc, qz.cc, rand.cc, rcond.cc, regexp.cc, schur.cc, spparms.cc, sqrtm.cc, str2double.cc, strfind.cc, sub2ind.cc, svd.cc, syl.cc, time.cc, tril.cc, typecast.cc: Move functions from DLD-FUNCTIONS/ to corefcn/ directory. Include "defun.h", not "defun-dld.h". Change docstring to refer to these as "Built-in Functions". * build-aux/mk-opts.pl: Generate options code with '#include "defun.h"'. Change option docstrings to refer to these as "Built-in Functions". * corefcn/module.mk: List of functions to build in corefcn/ dir. * DLD-FUNCTIONS/config-module.awk: Update to new build system. * DLD-FUNCTIONS/module-files: Remove functions which are now in corefcn/ directory. * src/Makefile.am: Update to build "convenience library" in corefcn/. Octave program now links against all other libraries + corefcn libary. * src/find-defun-files.sh: Strip $srcdir from filename. * src/link-deps.mk: Add REGEX and FFTW link dependencies for liboctinterp. * type.m, which.m: Change failing tests to use 'amd', still a dynamic function, rather than 'dot', which isn't.
