Fixed compilation warnings

Combine HashTable.flags and HashTable.nApplyCount into single 32-bit word

Use ZEND_HASH_FOEACH_* instead of zend_hash_apply_*

More ZEND_HASH_FOREACH_* related changes

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

Add only_integer_keys option to zend_hash_reindex

This allows to either do a full reindex, or only reindex the integer
keys.

Add zend_hash_splice

This implements the original functionality of php_splice, but
as an in-place operation, thus avoiding copying the HT.

This is much faster (~10x) if the spli

Add zend_hash_splice

This implements the original functionality of php_splice, but
as an in-place operation, thus avoiding copying the HT.

This is much faster (~10x) if the splice removes a small portion
of the array and doesn't insert many elements.

Add zend_hash_reindex

The implementation differs from the original in array.c in that it
rehashes the hashtable in the same loop. This is approximately two
times faster (not counting

Add zend_hash_reindex

The implementation differs from the original in array.c in that it
rehashes the hashtable in the same loop. This is approximately two
times faster (not counting the rare case of a purely associative
array).

Refactored zend_hash_* iteration API zend_hash_fove_forward_ex(ht, pos) and family require second argument to be real pointer.
&(ht)->nInternalPointer should be passed instead of NULL.

&(ht)->nInternalPointer should be passed instead of NULL.
zend_hash_update_current_key() may work only with internal pointer.

Fixed extract() support IS_INDIRECT

Refactored IS_INDIRECT usage for CV and object properties to support HashTable resizing

Fixed serialize/unserialize problems

Fixed memory leak while add_mem faile

Removed unused "pHashFunction" argument in _zend_hash_init() and family (must be 99% source compatible)

Removed duplicated hash function implementation (100% source compatible)
