Add ability to disable JIT for a particular auto global

- Fix problem when using old-style constructors it wasn't being inherited
correctly.

Clearify the different method/class flags (as discussed with Andi).

- Nuke unused code.

- Fix some small problems I introduce in last patch.

- Finally fix the following:
$xml_mem = simplexml_load_string('<bookbody><part><chapter><page>1</page></chapter></part></bookbody>');
/* The following works fine */
foreach ($xml_mem->par

- Finally fix the following:
$xml_mem = simplexml_load_string('<bookbody><part><chapter><page>1</page></chapter></part></bookbody>');
/* The following works fine */
foreach ($xml_mem->part as $part) {
foreach($part->chapter->page as $page) {
print $page;
}
}
/* The following segfaults */
foreach ($xml_mem->part as $part) {
foreach($part->chapter as $chapter) { // Difference here from previous example
print $chapter;
}
}

Disallow redefining ctors and cleanup

- Fix leaks (although there might be still a problem here).

- Fix crash in:
<?php
class Foo {
public $attributes= array();

function export() {
foreach ($this->attributes as $name => $attr) {
}
}

- Fix crash in:
<?php
class Foo {
public $attributes= array();

function export() {
foreach ($this->attributes as $name => $attr) {
}
}
}

$f= new Foo();
$f->export();
?>

- Change prototype isA check not to check the constructor.
- Only give an E_STRICT for non-isA compliant code as opposed to
E_COMPILE_ERROR.

Fixes for abstract classes/methods

Fix leak in foreach ($o->mthd()->arr)

- Improve ARG_INFO() macros to support supplying required_num_args
- Initial fix for foreach($o->mthd()->arr) crash (now leaks)

- Rename compatiblity mode to zend.ze2_compatibility_mode (it doesn't only affect auto-clone).
- Perform implementation checks even with simple inheritance (off when
compatibility mode is

- Rename compatiblity mode to zend.ze2_compatibility_mode (it doesn't only affect auto-clone).
- Perform implementation checks even with simple inheritance (off when
compatibility mode is enabled).
- Restore default arguments in interfaces and handle it correctly.
- Move registration of internal classes later in the startup sequence
in order to have INI options available.

- Abstract methods cannot have defaults for arguments
- Make function foo($a, $b=null) satisfy both foo($a) and foo($a, $b)
prototypes

Bugfix #27227 Mixed case class names causes Fatal Error in Constructor call

- Check return-by-reference bit when implementing interface prototypes
- Add infrastructure for built-in functions to hint whether they
return by reference or not. It is NOT currently used

- Check return-by-reference bit when implementing interface prototypes
- Add infrastructure for built-in functions to hint whether they
return by reference or not. It is NOT currently used for anything,
except for interface prototypes (you can use it to request that the
function that implements your prototype returns by reference or
doesn't return by reference).
For downwards compatibility - by default, interface prototypes are
agnostic as to whether the function that implements them returns
by reference or not. Use ZEND_BEGIN_ARG_INFO_EX() with
ZEND_RETURN_VALUE/ZEND_RETURN_REFERENCE to change that.
- Fix ArrayAccess::getOffset() to conduct additional checks.
If your getOffset() should work with multidimensional arrays - it
must return by reference.

Fix: <interface> [extends <interface> [, <ineterface>]* ]

Fix bug #26802 (the right aspects of it found by Marcus, anyway :)

- Nuke more unused code

- Remove junk

Fixed bug #27145 (Unmangle private/protected property names before printing
then inside error messages).
