Bugfix #27227 Mixed case class names causes Fatal Error in Constructor call

return by reference or not. It is NOT currently used

- 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.

Fix: <interface> [extends <interface> [, <ineterface>]* ]

Fix bug #26802 (the right aspects of it found by Marcus, anyway :)

Reinstate early-binding for classes.

Note that this is available for downwards compatibility only - and it doesn't
work if you use new features (namely, interfaces). Generally, people should
declare their classes before using them, but we just didn't want hell to break
loose (c)

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

Using clone directly is now done using

Clone methods must now be declared as follows:

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