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.

Prohibit direct update of GC_REFCOUNT(), GC_SET_REFCOUNT(), GC_ADDREF() and GC_DELREF() shoukf be instead.
Added mactros to validate reference-counting (disabled for now).
These macros are going to be used to eliminate race-condintions during reference-counting on data shared between threads.
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.
apache2filter was supported in PHP <= 5.6. This patch removes some old
apache2filter occurrences. Also FreeBSD warning therefore is not needed
anymore when building PHP with apache2filter and in later versions don't
need to set the --with-tsrm-pth option.
