Merge branch 'PHP-5.6'

* PHP-5.6:
Fix bug #67433 SIGSEGV when using count() on an object implementing Countable

Fix bug #67433 SIGSEGV when using count() on an object implementing Countable

Optimized for fast path

Fixed compilation warnings

Use reference counting instead of zval duplication

Optimized conditions order

Introduced immutable arrays. They don't need to be copyed and may be used directly from SHM.

Use specialized functions instead of macros

Fix in_array (strict) with references

Use optimized zend_array_dup() function. convert zend_hash_num_elements() and zend_hash_next_free_element() into macros.

Make they are in the same style of Z_ISREF

Split IS_BOOL into IS_FALSE and IS_TRUE

Replace more convert_to_* calls

Move more code to use zval_get_string

Merge mainstream 'master' branch into refactoring
During merge I had to revert:
Nikita's patch for php_splice() (it probably needs to be applyed again)
Bob Weinand's patch

Merge mainstream 'master' branch into refactoring
During merge I had to revert:
Nikita's patch for php_splice() (it probably needs to be applyed again)
Bob Weinand's patches related to constant expression handling (we need to review them carefully)
I also reverted all our attempts to support sapi/phpdbg (we didn't test it anyway)

Use ZEND_FETCH_FOREACH_* macros to iterate over HashTables instead of zend_hash_move_forward() and family.

Fixed zend_string/char mess
