Fixed bug #67725 (now we create immutable arrays only in SHM)

Fixed string destruction (class_name might be reused and stored somewhere in __autoload()).

Removed EG(called_scope) and use corresponding value from EG(current_execute_data)

Removed EG(in_execution). If EG(currentent_execute_data) is not NULL we are executing something.

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

Don't use cast (compiler friendly)

Optimized constant lookup

Fixed compilation warnings

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

Moved zend_literal->cache_slot right into zval.
It should be accessed using Z_CACHE_SLOT() macro.
zend_literal structure is removed.
API functions that accepted pointer to zend_literal no

Moved zend_literal->cache_slot right into zval.
It should be accessed using Z_CACHE_SLOT() macro.
zend_literal structure is removed.
API functions that accepted pointer to zend_literal now accept pointer to zval or cache_slot directly.
Calls of such functiond that now accept cache_slot need to be changed to pass -1 instead of NULL.

Cleanup (2-nd round)

Cleanup (1-st round)

Fixed interface constants inheritance.
Now we use IS_REFERENCE for inhereted class constants.
I might miss some edje cases.

Removed useless void* parameter and replaced with zend_bool on zval_update_constant* functions

Fix copying of constants for ZTS

Just a quick hack, should probably add an internal_copy_ctor
function for this.

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

Use STR_COPY() instead of STR_DUP() where possible

Fixed invalid free

Fixed __COMPILER_HALT_OFFSET handling

Fixed constant name construction
