	(evaluate_subexp_standard): Handle values of type
	TYPE_CODE_INTERNAL_FUNCTION.
	* gdbtypes.h (type_code): Add TYPE_CODE_INTERNAL_FUNCTION.
	* parse.c (write_exp_string): Remove duplicate word in comment.
	* python/python-function.c: New file.
	* python/python-internal.h (gdbpy_initialize_functions): Add
	prototype.
	* python/python.c (_initialize_python): Call
	gdbpy_initialize_functions.
	* valprint.c (value_check_printable): Handle values of type
	TYPE_CODE_INTERNAL_FUNCTION.
	* value.c: Include "cli/cli-decode.h".
	(internal_function): New struct.
	(functionlist, internal_fn_type): New static variables.
	(lookup_only_internalvar,
	lookup_internalvar): Add const qualifier to name argument.
	(create_internalvar): Likewise.  Initialize new field.
	(set_internal_var): Fix typo in comment.  Don't allow assignment
	to canonical variable.
	(value_create_internal_function, value_internal_function_name,
	call_internal_function, function_command, function_destroyer,
	add_internal_function): New functions.
	(_initialize_values): Create `function' placeholder command.
	Initialize internal_fn_type.
	* value.h (lookup_only_internalvar, create_internalvar,
	lookup_internalvar): Add const qualifier to name argument.
	(internal_function_fn, add_internal_function, call_internal_function,
	value_internal_function_name): Add prototypes.
