Fixed string interning during constants substitution

Use interned strings for stream transports

Use interned strings for persistent stream wrappers and filters

Always calculate calculate string hash value on attempt of interning

Use internet strings for EG(ini_entries)

Encapsulate reference-counting primitives.
Prohibit direct update of GC_REFCOUNT(), GC_SET_REFCOUNT(), GC_ADDREF() and GC_DELREF() shoukf be instead.
Added mactros to validate reference-count

Added mactros to validate reference-counting (disabled for now).
These macros are going to be used to eliminate race-condintions during reference-counting on data shared between threads.

Constify key access for hash and formal params

Keys created in shared memory and won't be modified and are free'd on
restart. Otherwise, keys passed to functions should not be modified,

Extend zend_string API to avoid reallocation in zend_string_init_interned()

Moved ZCG(function_table) back into accel_acrivate. It should be unique per thread.

Move a part of opcache initialization into post_startup phase (when all extensions already loaded).

Backport 7ff13badda58b966ff8fbcc61add48bb5b14117b into 7.0+

Fixed required SHM memeory size calculation for scripts when opcache.revalidate_path is set.

Reuse interned strings from opcache SHM, if possible.

apache2filter was supported in PHP <= 5.6. This patch removes some old
apache2filter occurrences. Also FreeBSD warning therefore is not needed
anymore when building PHP with apache2filter and in later versions don't
need to set the --with-tsrm-pth option.

Move cwd_state and path related routines to size_t

Having `int` there is no real profit in the size or speed, while unsigned
improves security and overall integration. ZPP supplied strings can
be then accepted directly and structs can be still handled with smaller
unsigned types for size reasons, which is safe. Yet some related places
are to go.

basic move tsrm_realpath_r to size_t

fix conditions and sync with affected places

touch ocurrences of php_sys_readlink usage

follow up on phar path handling

Remove old references to SAPIs and extensions no longer in the core

Remove superfluous semicolons

shutdown_executor() refactoring (reuse opcache fast request shutdown code)

Setting CG(unclean_shutdown) in fast shutdown doesn't make a lot of sense (it was set to prevent memory leak messages, but we doesn't check memory leaks in RELEASE build anyway).

Clear alocated memory blocks, only if this is really necessary.

Introduced "zif_handler" type (zif = zend internal function).

Fixed bug #74663 (Segfault with opcache.memory_protect and validate_timestamp)

Fixed bug #74596 (SIGSEGV with opcache.revalidate_path enabled)

Yeah, no test script is provided.. I got some troubles to make a one

drop redundant checks

move to hash API
