exit_on_timeout patch

After the sigsetjmp change, this is patch #2 in an effort to get some
sanity restored to signal handling in PHP.

This patch does two things. First, it makes it possible to reset the
timeout without resetting the signal handlers. This is important for
cases where an extension may have deferred signals in its MINIT in order
to implement critical sections. It also lays the groundwork for cleaning
up our signal handling and perhaps eventually implementing our own
signal deferring mechanism so we can have true critical sections.

The second thing this does is to make it possible to terminate the current
child process (only for Apache1 at the moment) on a timeout. There are
a number of extensions that are unhappy about being longjmp'ed out of
and when this happens on a timeout they are left in an inconsistent state.
By turning on exit_on_timeout you can now force the process to terminate
on a timeout which will clean up any hanging locks and/or memory left
hanging after the longjmp.

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);

%v -> %s, this is 5_3

Fixed shared memory corruption of opcode caches

- MFH Add E_DEPRECATED (Lars Strojny, Felipe Pena, Marcus)
[DOC] Finally added deprecation messages

- MFH Add comment that explains why we need E_ERROR in those cases

- Fix flag handling in message generation

Fixed bug #43323 (Wrong count abstract methods). (Felipe, Dmitry)

Changed EG(argument_stack) implementation.

Added garbage collector

Changed exception handling. Now each op_array doesn't contain ZEND_HANDLE_EXCEPTION opcode in the end

- Fix the fix

- Fix memleak (found by colder)

Added missing warning message

MFH: Bump copyright year, 2 of 2.

Fixed bug #43651 (is_callable() with one or more nonconsecutive colons crashes)

Fixed bug #43344 (Wrong error message for undefined namespace constant)

Fixed bug #43128 (Very long class name causes segfault)

- MFH Improved version of ternary shortcut (Marcus)

Fixed bug #43136 (possible crash on script execution timeout. The EG(function_state_ptr) is completely removed, EG(current_execute_data)->function_state must be used instead)

- MFH from HEAD:
. Folding tags
. Parameter parsing
. SPL debug info
. array function improvements (not all yet)
. Improvements to function calling with call_user_* func

# I propably forgot already something but this all was pretty close tied
# to each other so it wasn't possible to do it in parts.

Reimplemented support for namespaces in indexes id constant arrays (removed zval.idx_type)

MFH: Added macros for managing zval refcounts and is_ref statuses

Fixed bug #42820 (defined() on constant with namespace prefixes tries to load class).
