Enable throwing custom exceptions from errors

Use ZSTR_ API to access zend_string elements (this is just renaming without semantick changes).

Use the new 'ZSTR' macros in the rest of the code.

Does not change anything to the generated code (thanks to compat macros) but cleaner.

Improve zend_string API

Add missing methods

show more ...

Drop superfluous __toString handling code

This is already covered by the cast_object invokation above it. We
do not use this kind of fallback in any other casting code anymore.

Avoid zval duplication in ZVAL_ZVAL() macro (it was necessary only in few places).
Switch from ZVAL_ZVAL() to simpler macros where possible (it makes sense to review remaining places)

micro-optimization

Fixed zend_update_class_constants() to always resolve all constants.
Call zend_update_class_constants() only when necessary.

Use zend_string to represent pdo_column_data.name and avoid duplication.

Micro optimizations

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.

Use fast method to check if first arguments should be passed by reference (not tested onbig endian).

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 Removed "Array was modified outside object and internal position is no longer valid" hack.

Always throw TypeException on throwing zpp failures

Introduces a ZEND_PARSE_PARAMS_THROW flag for zpp, which forces to
report FAILURE errors using a TypeException instead of a Warning,
like it would happen in strict mode.

Adds a zend_parse_parameters_throw() convenience function, which
invokes zpp with this flag.

Converts all cases I could identify, where we currently have
throwing zpp usage in constructors and replaces them with this API.
Error handling is still replaced to EH_THROW in some cases to handle
other, domain-specific errors in constructors.
