Bug #44653 (Invalid namespace name resolution)

MFH: Implemented "jump label" operator (limited "goto")
[DOC]

Removed unused variable

MFH:
- Renamed zend_do_fetch_class_name() to zend_do_build_full_name() (It is not used only for classes)
- Moved zend_resolve_class_name prototype to zend_compile.h

- Simplify

Removed hack (we don't need to modify class name).
(the problem is covered by Zend/tests/ns_056.phpt)

Implemented concept of "delayed early binding" that allows opcode caches to perform class declaration (early and/or run-time binding) in exactly the same order as vanila php.

Implemented concept of "delayed early binding" that allows opcode caches to perform class declaration (early and/or run-time binding) in exactly the same order as vanila php.
The following pseudo-code explains how it should be used in opcode cache.

function cache_compile_file($filename) {
if (!is_cached($filename)) {
...
orig_compiler_options = CG(compiler_optins);
CG(compiler_options) |= ZEND_COMPILE_IGNORE_INTERNAL_CLASSES |
ZEND_COMPILE_DELAYED_BINDING;
$op_array = orig_compile_file($filename);
CG(compiler_options) = orig_copiler_options;
...
} else {
$op_array = restore_from_cache($filename);
}
zend_do_delayed_early_binding($op_array);
}
