Merged TMP and VAR specializations of ZEND_FETCH_OBJ_R.
Allowed dispatching to less specialized handelrs and helpers. (e.g. from OP_TMP_CONST to OP_TMPVAR_CONST).

Prevent reference-counting on persistent zvals (internal constants, default properties and constants of internal classes).

New macro ZVAL_COPY_OR_DUP() is used perform duplication, if necessary.
This should eliminate related race-coditions in ZTS build and prevent reference-counting bugs after unclean shutdown.

These macros are going to be used to eliminate race-condintions during reference-counting on data shared between threads.

Allow internal functions to return values by reference (this was disabled in implementation of DO_ICALL, but enabled in DO_FCALL).
...
However, don't require internal functions returning by reference to return a reference.
Mark unserialize() as returning by reference and remove unwrap_reference hack, to allow proper returning of self referenced arrays using a reference.
Currently unserialize() is the only internal function that may return a reference.
