Rebase Joe's anon classes implementation

Don't propogate "fake" EX(called_scope) and EX(This) into each internal function.
They need quite seldom and it's cheaper to get them from corresponfing upper stack frame.

* master:
Fixed GOTO executor
Fixed typo
Changed ArrayIterator implementation using zend_hash_iterator_... API. Allowed modification of itterated ArrayObject using the same behavior as proposed in `Fix "foreach" behavior`. Removed "Array was modified outside object and internal position is no longer valid" hack.

Recalssify some E_ERROR into E_CORE_ERROR

Convert fatal errors into EngineExceptions
Make zval_update_constant_ex(), zval_update_constant(), zend_update_class_constants() and zend_ast_evaluate() return SUCCESS or FAILURE.

Use zend_error_noreturn() for fatal errors

Added missing zend_parse_parameters_none() to restore_error_handler() and restore_exception_handler() (Ferenc)

Minor cosmetics for our test functions in the debug build

Change "Cannot redeclare class X" into "Cannot redeclare class/interface/trait X", meaning that the following:

C:\> php -r "trait A { } trait A { }"

Will now properly print "Cannot redeclare trait A" instead of "Cannot redeclare class A" to make error messages a tiny bit clearer. Admittedly, a better solution can most likely be made by actually telling what the colliding object is a type of.

Internally this adds a new function:
zend_get_object_type()

DO_UCALL - for user functions
DO_FCALL_BY_NAME - plain, most probably user, funcstions (not methods)

CC_TRAIT valued as 0x120 is too magical to be comprehensible by others.
