If a (nested) unserialize() call fails, we remove all the values
that were inserted into var_hash during that call. This prevents
their use in other unserializations in the same context.
Don't call __destruct() on an unserialized object that has a
__wakeup() method if either
a) unserialization of its properties fails or
b) the __wakeup() call fails (e.g. by throwing).
This basically treats __wakeup() as a form of constructor and
aligns us with the usual behavior that if the constructor call
fails the destructor should not be called.
The security aspect here is that people use __wakeup() to prevent
unserialization of objects with dangerous __destruct() methods,
but this is ineffective if __destruct() can still be called while
__wakeup() was skipped.
The (UN)SERIALIZE_INIT/DESTROY macros now go through non-inlined
functions, so any changes to them will apply to extensions without
rebuilds.
Additionally, the (un)serialize_data structures are now no longer
exported.
This means that we are allowed to change these structures in patch
releases without breaking the ABI.
These are either in debug code (fix them), commented out (drop
them) or in dead compatibility macros (drop them).
One usage was in php_stream_get_from_zval(), which we have not used
since at least PHP 5.2 and, judging from the fact that nobody
complained about it causing compile errors in PHP 7, nobody else
uses it either, so drop it.
There are still remaining uses in mysqli embedded and odbc birdstep.
These probably need to be dropped outright.

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.
