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

Optimize int to string conversion

Probably platform depedentant, but for me snprintf is terribly
slow.

The code for the long printing is taken from the smart string
API.

Assert that EMPTY_SWITCH_DEFAULT_CASE() cannot be reached in debug

C89 compat

Added vstrpprintf strpprintf to avoid duplicate string

(the function name maybe improvement)

Fix identical comparison of arrays with references

Also commit a test I forgot.

Fix SXE->string cast for __toString in inheriting class

This issue was originally hacked around in zend_make_printable_zval.
I've now moved the overridden __toString() handling into the

Fix SXE->string cast for __toString in inheriting class

This issue was originally hacked around in zend_make_printable_zval.
I've now moved the overridden __toString() handling into the SXE
cast_object handler, so everything invoking that handler
(zend_make_printable_zval, convert_to_string, zval_get_string,
and various other more obscure usages) see the same behavior.

Avoid superflous allocations in convert_to_string

Taken from zval_get_string.

Split IS_BOOL into IS_FALSE and IS_TRUE

Add dst parameter to convert_object_to_type macro

Avoids a ZVAL_DUP in the zval_get_* functions.

Also improve object-to-array cast a bit by initializing the array
with correct n

Add dst parameter to convert_object_to_type macro

Avoids a ZVAL_DUP in the zval_get_* functions.

Also improve object-to-array cast a bit by initializing the array
with correct number of elements and not doing a alloc-init-free
cycle when convert_object_to_type succeeds.

Use convert_scalar_to_array only for arrays

Align zval_get_long/double with zval_get_string

Fixed compilation warnings

Use shorter call chain

Convert zval_get_string() into "fast path" macro and "slow path" function

Use zval_get_string in a few more places

Bring zval_get_string implement in line with make_printable_zval

As make_printable_zval is the "main" string cast, match that one.

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

Add functions for extracting long/double/string from zval

These function get the long / double / string value of a zval with
usual cast semantics, but without actually modifying the zval

Didn't go on a killing spree for convert_to_* yet...

Cleanup (1-st round)

Fixed zend_object_get_t in simpleXML

Fix ZTS build

This only makes it compile, it doesn't actually work, presumably
because interned strings are assumed in some places.

Refactored ZVAL flags usage to simplify various checks (e.g. Z_REFCOUNTED(), candidate for GC, etc)

Changed data layout to allow more efficient operations

STR_DUP() doesn't duplicate interned strings anymore. In case new string is required STR_INIT() or STR_ALLOC() should be used.
