implemented again zend-multibyte for PHP 5.3

Lazy EG(active_symbol_table) initialization

Fixed bug #44226 (Throwing an exception causes crash in multithreaded SAPI)

Optimized ZEND_RETURN opcode to not allocate and copy return value if it is not
used.

Make the sigsetjmp change more robust. On systems that don't have
sigsetjmp use setjmp. Windows is of course weird in that it seems to
have sigsetjmp but not sigjmp_buf (??) so force it to

sigsetjmp use setjmp. Windows is of course weird in that it seems to

Use sigsetjmp and siglongjmp instead of setjmp/longjmp in order to be

Use sigsetjmp and siglongjmp instead of setjmp/longjmp in order to be
consistent in how we deal with the signal mask. POSIX doesn't specify
what to do with the signal mask in setjmp/longjmp which has resulted in
the signal mask getting saved on *BSD and not getting saved on Linux.
Making the behaviour explicit via sigsetjmp/siglongjmp gives us
consistency and saves expensive sigprocmask() syscalls on *BSD.

MFH: Dropped zend.ze1_compatibility_mode

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);
