Add support for tentative return types of internal methods

Property handle unset name on ReflectionClassConstant

While the typed property ensures that the value is a string,
we should make sure that we handle an unset property gracefully.

While the typed property ensures that the value is a string,
we should make sure that we handle an unset property gracefully.

Do this by throwing the same error we would normally throw if
you access an uninitializde typed property.

1. Update: http://www.php.net/license/3_01.txt to https, as there is anyway server header "Location:" to https.
2. Update few license 3.0 to 3.01 as 3.0 states "php 5.1.1, 4.1.1, and earlier".
3. In some license comments is "at through the world-wide-web" while most is without "at", so deleted.

Improve fiber backtraces

The start/resume/throw execute_data is now attached as the prev_execute_data to the bottom frame of the fiber stack when the fiber is running.

Filter return value of ReflectionClassConstant::getModifiers()

Don't return internal flags like IS_CASE.

Add ZEND_CLASS_CONST_FLAGS() macro

And drop Z_ACCESS_FLAGS(). We no longer store *only* access flags
in these.

Implement never return type

The never type can be used to indicate that a function never
returns, for example because it always unwinds.

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).

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.

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.

Fix build

We cannot `RETURN_THROWS()` here, since `return_value` is not defined.
