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.
