Don't allocate temporary file cache memory on arena During unserialization, static_variables and runtime_cache may be allocated on the arena, and then later freed when the checkpoint is released. As we're only doing a single large allocation here, simply move this to the normal allocator, so there is no interference with other arena allocations.

Fast Class Cache This is generalization of idea, that was previously usesd for caching resolution of class_entries in zend_type. Now very similar mechanizm is used for general zend_string into zend_class_entry resolution. Interned zend_string with IS_STR_CLASS_NAME_MAP_PTR GC_FLAG uses its refcount to adress corresponding zend_class_entry cache slot. The refcount keeps an offset to this slot from CG(map_ptr_base). Flag may be checked by ZSTR_HAS_CE_CACHE(str), cache slot may be read by ZSTR_GET_CE_CACHE(str) and set by ZSTR_SET_CE_CACHE(str, ce).

Reference dynamic functions through dynamic_defs Currently, dynamically declared functions and closures are inserted into the function table under a runtime definition key, and then later possibly renamed. When opcache is not used and a file containing a closure is repeatedly included, this leads to a very large memory leak, as the no longer needed closure declarations will never be freed (https://bugs.php.net/bug.php?id=76982). With this patch, dynamic functions are instead stored in a dynamic_func_defs member on the op_array, which opcodes reference by index. When the parent op_array is destroyed, the dynamic_func_defs it contains are also destroyed (unless they are stilled used elsewhere, e.g. because they have been bound, or are used by a live closure). This resolves the fundamental part of the leak, though doesn't completely fix it yet due to some arena allocations. The main non-obvious change here is to static variable handling: We can't destroy static_variables_ptr in destroy_op_array, as e.g. that would clear the static variables in a dynamic function when the op_array containing it is destroyed. Static variable destruction is separated out for this reason (we already do static variable destruction separately for normal functions, so we only need to handle main scripts). Closes GH-5595.

Fix static variable behavior with inheritance When a method is inherited, the static variables will now always use the initial values, rather than the values at the time of inheritance. As such, behavior no longer depends on whether inheritance happens before or after a method has been called. This is implemented by always keeping static_variables as the original values, and static_variables_ptr as the modified copy. Closes GH-6705.

Added Inheritance Cache. This is a new transparent technology that eliminates overhead of PHP class inheritance. PHP classes are compiled and cached (by opcahce) separately, however their "linking" was done at run-time - on each request. The process of "linking" may involve a number of compatibility checks and borrowing methods/properties/constants form parent and traits. This takes significant time, but the result is the same on each request. Inheritance Cache performs "linking" for unique set of all the depending classes (parent, interfaces, traits, property types, method types involved into compatibility checks) once and stores result in opcache shared memory. As a part of the this patch, I removed limitations for immutable classes (unresolved constants, typed properties and covariant type checks). So now all classes stored in opcache are "immutable". They may be lazily loaded into process memory, if necessary, but this usually occurs just once (on first linking). The patch shows 8% improvement on Symphony "Hello World" app.

Add system ID entropy API The `zend_system_id` is a (true global) system ID that fingerprints a process state. When extensions add engine hooks during MINIT/startup, entropy is added the system ID for each hook. This allows extensions to identify that changes have been made to the engine since the last PHP process restart. Closes GH-5871

Implement named parameters From an engine perspective, named parameters mainly add three concepts: * The SEND_* opcodes now accept a CONST op2, which is the argument name. For now, it is looked up by linear scan and runtime cached. * This may leave UNDEF arguments on the stack. To avoid having to deal with them in other places, a CHECK_UNDEF_ARGS opcode is used to either replace them with defaults, or error. * For variadic functions, EX(extra_named_params) are collected and need to be freed based on ZEND_CALL_HAS_EXTRA_NAMED_PARAMS.
