Improved shared interned strings handling. The previous implementation worked incorrectly in ZTS build. It changed strings only in function/class tables of one thread. Now all threads gets the same shared interned strings. Also, on shutdown, we don't try to replace SHM interned strings back to process strings, but delay dettachment of SHM instead.

Remove old SVN keywords substitutions

When the PHP source code was versioned in Subversion, there was
possible to substitute certain keywords such as $Id$ with revision
number, last change time and author name. Such approach is not used
in Git so this patch removes these outdated artifacts from source
code files.

Use zend_string_release_ex() instread of zend_string_release() in places, where we sure about string persistence.

Avoid useless checks, using zend_string_efree(), in cases where the string is known to be a temporary allocated zend_string.

micro optimization

Use "fastcall" calling convention

Removed commented unoptimized code

year++

Use GC_FLAGS_SHIFT in a few more places

Rather than hardcoding 8.

Implemented x86 and x86_64 assembler functions for zend_string equality check.
They take into account zend_string layout (value alignment and trailing padding) and perform comparison by double or

Implemented x86 and x86_64 assembler functions for zend_string equality check.
They take into account zend_string layout (value alignment and trailing padding) and perform comparison by double or quad words.

Use zend_string_equal*() API for zend_string equality check instead of direct memcmp() usage.

Added "argv" and "argc" as known strings.
Fixed incorrect "argc" update and corresponding phpdbg test.

Switch back from "request" interned strings storage to "permanent" in MSHUTDOWN

Use known strings for reflection properties

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

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

Extend zend_string API to avoid reallocation in zend_string_init_interned()

further sync for vim mode lines

Added ZEND_GET_CLASS, ZEMD_GET_CALLED_CLASS, ZEND_GET_TYPE instructions, to implement corresponding builtin functions.

Optimized parse_url() by using "known" strings

Interned strings unification for TS/NTS

Hereby, interned strings are supported in thread safe PHP. The patch
implements two types of interned strings

- interning per process, strings are not freed till process end
- interning per request, strings are freed at request end

There is no runtime interning.

With Opcache, all the permanent iterned strings are copied into SHM on
startup, additional copying into SHM might happen on demand.
