Nested functions and functions with nested functions can be evaluated by the
VM.

* libinterp/corefcn/call-stack.cc: Push bytecode frame for nested functions
* libinterp/corefcn/call-stack.h
* libinterp/corefcn/stack-frame.cc: Support saving bytecode frames,
frameoffset ...
* libinterp/corefcn/stack-frame.h
* libinterp/octave-value/ov-fcn-handle.cc: Compile nested function handles
                                           Refactor VM call and is compiled
check.
* libinterp/octave-value/ov-fcn.cc: Refactor compiled check and VM call
* libinterp/octave-value/ov-ref.cc: New ref octave_value_ref_ptr for nested
frames
* libinterp/octave-value/ov-ref.h
* libinterp/octave-value/ov-usr-fcn.cc: Refactor vm call and compiled check
* libinterp/octave-value/ov.h: octave_value_ref_ptr friend to call is_ref()
and ref_rep ()
* libinterp/parse-tree/pt-bytecode-vm.cc: Function caches might be written to
refs
                                          New vm::call () and
vm::maybe_compiled_or_compile ()
                                          Call bytecode for command functions.
* libinterp/parse-tree/pt-bytecode-vm.h
* libinterp/parse-tree/pt-bytecode-walk.cc: Compile nested functions, set up
variables
* libinterp/parse-tree/pt-bytecode-walk.h
* libinterp/parse-tree/pt-bytecode.h: New opcode ENTER_NESTED
* libinterp/parse-tree/pt-eval.cc: Push nested frame, refactor how VM is
called
* libinterp/parse-tree/pt-eval.h
* test/compile/bytecode.tst: Tests added
* test/compile/module.mk
* test/compile/bytecode_nested.m
* test/compile/cdef_bar.m: Self-counting test class
