Remodel exceptions based on Throwable interface

Added Throwable interface that exceptions must
implement in order to be thrown. BaseException
was removed, EngineException renamed to

renamed to TypeError and ParseError. Exception
and Error no longer extend a common base
class, rather they both implement the Throwable
interface.

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.

Convert fatal errors into EngineException

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

Fixed destruction of objects and iterators on unclean request shutdown and GC (few cases are still unfixed).
Now we destroy objects it two steps. At first - object properties of all objects and only then the objects their selves.
