Clearify the different method/class flags (as discussed with Andi).

- Nuke unused code.

- Typo fix (by Jan)

add ZEND_API there too for opcode handlers

Add some comments

- Improve ARG_INFO() macros to support supplying required_num_args
- Initial fix for foreach($o->mthd()->arr) crash (now leaks)

- Abstract methods cannot have defaults for arguments
- Make function foo($a, $b=null) satisfy both foo($a) and foo($a, $b)
prototypes

- Check return-by-reference bit when implementing interface prototypes
- Add infrastructure for built-in functions to hint whether they
return by reference or not. It is NOT currently used for anything,
except for interface prototypes (you can use it to request that the
function that implements your prototype returns by reference or
doesn't return by reference).
For downwards compatibility - by default, interface prototypes are
agnostic as to whether the function that implements them returns
by reference or not. Use ZEND_BEGIN_ARG_INFO_EX() with
ZEND_RETURN_VALUE/ZEND_RETURN_REFERENCE to change that.
- Fix ArrayAccess::getOffset() to conduct additional checks.
If your getOffset() should work with multidimensional arrays - it
must return by reference.

Rewrote exception support. Fixes a few limitations and bugs in the old
implementation, and allows exceptions to 'fire' much earlier than before.

Instructions on how to use the new mechanism will follow on internals@
shortly...

Note - this (most probably) breaks the current implementation of
set_exception_handler()

Redesign the clone() feature to fix some fundamental flaws in the previous
implementation.

Using clone directly is now done using
$replica = clone $src;

Clone methods must now be declared as follows:
function __clone($that)
{
}

Clone methods in derived classes can call the __clone method of their parent
classes using parent::__clone($that)

Switch from ZEND_ACC_DYNAMIC to ZEND_ACC_ALLOW_STATIC and disallow calling
internal non-static methods statically.
# As discussed with Zeev:
# - For BC standard userspace methods allow this with an E_STRICT message.
# - If you want to implement an internal method taht can be called both
# statically and non-statically then use flag ZEND_ACC_ALLOW_STATIC.
# - Magic user space methods __*() cannot and __construct, __destruct,
# __clone can never be called statically.

Simplify detection of methods that must be called dynamic (with object)

Disallow static declaration of clone

- Happy new year and PHP 5 for rest of the files too..
# Should the LICENSE and Zend/LICENSE dates be updated too?

- Fixed var_export() to show public, protected and private modifiers properly.
- Exported (un)mangle_property_name.

Sync: Export externally used functions.

Fix behavior of return-by-reference functions. Remove erroneous warnings,
add E_STRICT warnings in case you return something by reference that you're
not supposed to (anything that's not a variable, or a return-value of a
function that returned by reference).

- Fix __autoload() to preserve class case.
- Heads up, this patch might break stuff so please let me know if you
- bump into any problems.

Split isset/isempty for object property and object dimension hooking.

Expand Interface C API.
In short: zend_class_entry->interface_gets_implemented() allows to modify
the class entry of a class when an interface gets implemented.

Don't identify alias'ed functions

- Add fn_flag ZEND_ACC_ALIAS
- Unify way of function_entry generation by new macro ZEND_FENTRY

Internal classes can now have default properties.
