rename OCTAVE_USE_DEPRECATED_FUNCTIONS macro and attempt to make it work
For ordinary functions declared in a header file and defined in a
corresponding source file, it should be OK to omit the declaration in
the header file based on the value of
OCTAVE_PROVIDE_DEPRECATED_SYMBOLS. But it is an error to attempt to
define a member function that has not been declared in the class
declaration. So for these, we rename the original function to be
FOO_deprecated and then provide a wrapper function called FOO that is
completely defined in the header file and simply calls the
FOO_deprecated function.
* mk-octave-config-h.sh, oct-conf-post.in.h
(OCTAVE_PROVIDE_DEPRECATED_SYMBOLS): Rename from
OCTAVE_USE_DEPRECATED_FUNCTIONS. Change all uses. For deprecated
member fucntions, use private FOO_deprecated member functions and
conditionally defined inline public wrappers to allow declarations of
deprecated symbosl to be omitted if OCTAVE_PROVIDE_DEPRECATED_SYMBOLS
is not defined.
