Allow NULL, too

Fix fn_flags handling

Add property read code and use that in default exception class

Internal classes can now have default properties.

- Flag ctor/dtor methods
- Use this to prevent memleaks when an exception gets thrown in ctors.

If ce not given than any object would do

Paramspec 'O' / zend_parse_method_params(): only if given check the class type

Improve tracking

- Show class names in error messages when dealing with methods
- Mark class as abstract if it gets an abstract method

Simplify abstract method declaration

- Show classes in case of methods
- Using sprintf here was a bad idea

Ensure functions have a valid access level

Default to public

Not needed, will be copied from ptr->flags later

ntroduce infrastructure for supplying information about arguments,
including:

- Whether or not to pass by ref (replaces the old arg_types, with arg_info)
- Argument name (for future use, maybe introspection)
- Class/Interface name (for type hints)
- If a class/interface name is available, whether to allow a null instance

Both user and builtin functions share the same data structures.

To declare a builtin function that expects its first arg to be an instance
of class 'Person', its second argument as a regular arg, and its third by
reference, use:

ZEND_BEGIN_ARG_INFO(my_func_arg_info, 0)
ZEND_ARG_OBJ_INFO(0, someone, Person, 1)
ZEND_ARG_PASS_INFO(0)
ZEND_ARG_PASS_INFO(1)
ZEND_END_ARG_INFO();

and use my_func_arg_info as the arg_info parameter to the ZEND_FE() family
of macros.

The first arg to each ZEND_ARG_*() macro is whether or not to pass by ref.

The boolean arg to ZEND_BEGIN_ARG_INFO() tells the engine whether to treat
the arguments for which there's no explicit information as pass by reference
or not.
The boolean argument to ZEND_ARG_OBJ_INFO() (4th arg) is whether or not to allownull values.

No need for this initialization - this function initializes all of the
elements of zend_internal_function

Initialize all struct members: Necessary for reflection

fix usage of instanceof here too

better fix...

Fix "O" format for zend_parse_parameters

Use instanceof_function()

Add exec_finished() callback for modules - this is the last place where the
modules may touch the symbol table reliably
