function had an invalid return. Any function call inbetween
will clear the error information.

Add optional second arg to unserialize()

Returns the number of bytes consumed by reference for
streaming unserialization.

Actual unserialization behavior is not modified at all.

The need for this came up while trying to parse SplDoublyLinkedList's
serialization format which uses a non-standard stream of serialized values.

Don't double-quote name of namespaced function.

ZEND_NS_NAMED_FE(ns, zend_name, name, arg_info)

was resulting in a function declaration of:

ns\"zend_name"()

including the errant quotes.

This diff corrects that.  There are currently no uses of ZEND_NS_NAMED_FE
in core and reason to believe that there are no uses in the wild either.
