4bd22cf1c1 Improved zend_string API (Francois Laupretre) 
Squashed commit of the following:

commit d96eab8d79
Author: Francois Laupretre <francois@tekwire.net>
Date:   Fri Jun 26 01:23:31 2015 +0200

    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.

commit b352643910
Author: Francois Laupretre <francois@tekwire.net>
Date:   Thu Jun 25 13:45:06 2015 +0200

b97df475df Fixed crash in Zend/tests/bug69891.phpt on x86 (32-bit). 
compare_function() now has to be compatible with binary_op_type (use fastcall convention).
Introduced new zval_compare_function() to be used as zval comparison callback instead of compare_function().

fb346c8f93 Support references in convert_to_* 
conver_to_* functions now accept REFERENCE values, which will be
unwrapped before performing the usual conversion. This is consistent
with convert_scalar_to_number and matches the expected behavior in
a couple random use-sites I checked.

Also includes a couple fixes/cleanups elsewhere and two tests for
cases that previously didn't work (though the reference issue existed
all over the place).

5d3cf577aa Make convert_to_* safe with rc>1 
This only involves switching zval_dtor to zval_ptr_dtor for arrays
and making the convert_to_object for arrays a bit more generic.

All the other changes outside zend_operators.c just make use of
this new ability (use COPY instead of DUP).

What's still missing: Proper references handling. I've seen many
convert_to* calls that will break when a reference is used.

Also fixes bug #69788.

e10e151e9b Merged zend_array and HashTable into the single data structure. 
Now each HashTable is also zend_array, so it's refcounted and may be a subject for Copy on Write
zend_array_dup() was changed to allocate and return HashTable, instead of taking preallocated HashTable as argument.

31e842472f Make number printing functions less generic 
Now that zend_ulong is 64bit on 64bit platforms, it should be
sufficient to always use it, rather than supporting multiple
types.

API changes:
 * _zend_print_unsigned_to_buf and _zend_print_signed_to_buf
   no longer exist.
 * smart_str(ing)_print_long and smart_str(ing)_print_unsigned
   no longer exist.
 * Instead of all these, zend_print_ulong_to_buf and
   zend_print_long_to_buf should be used.
 * smart_str_append_generic_ex no longer exists.
 * smart_str(ing)_append_off_t(_ex) no longer exists, use
   smart_str(ing)_append_long(_ex) instead.
