One bit fields need to be unsigned, otherwise there is no storage for
the sign bit

"A signed bit field has a length of 1 bit."

Add logical XOR, proves to be quite useful lately

ntroduce infrastructure for supplying information about arguments,
including:

- Whether or not to pass by ref (replaces the old arg_types, with arg_info)
- Argument name (for future use, maybe introspection)
- Class/Interface name (for type hints)
- If a class/interface name is available, whether to allow a null instance

Both user and builtin functions share the same data structures.

To declare a builtin function that expects its first arg to be an instance
of class 'Person', its second argument as a regular arg, and its third by
reference, use:

ZEND_BEGIN_ARG_INFO(my_func_arg_info, 0)
ZEND_ARG_OBJ_INFO(0, someone, Person, 1)
ZEND_ARG_PASS_INFO(0)
ZEND_ARG_PASS_INFO(1)
ZEND_END_ARG_INFO();

and use my_func_arg_info as the arg_info parameter to the ZEND_FE() family
of macros.

The first arg to each ZEND_ARG_*() macro is whether or not to pass by ref.

The boolean arg to ZEND_BEGIN_ARG_INFO() tells the engine whether to treat
the arguments for which there's no explicit information as pass by reference
or not.
The boolean argument to ZEND_ARG_OBJ_INFO() (4th arg) is whether or not to allownull values.

Add exec_finished() callback for modules - this is the last place where the
modules may touch the symbol table reliably

Remove namespace leftovers

Fix the HPUX alloca fix as suggested by Sascha

- Don't use alloca on HP-UX (Moriyoshi Koizumi <moriyoshi@at.wakwak.com>)

updating license information in the headers.

rm namespace leftovers

MEGA-patch: namespaces are R.I.P.

- Revert my symbol fix patch, and merge in Stas' fixes to Zend Engine 1.

- MacOSX also prepends the _ before symbols in bundles

Multi-purpose patch:
- The fields of zend_namespace were not completely initialized which
led to a variety of problems.
- The occurrence of class/interface/namespace definition is no

Multi-purpose patch:
- The fields of zend_namespace were not completely initialized which
led to a variety of problems.
- The occurrence of class/interface/namespace definition is now
captured.
- Functions/classes/interfaces/namespaces can be preceded by doc
comments which are stored for use by extensions.

Add support for interfaces

Avoid using a C++ reserved word

Implement simple stream support in the ZE scanners.

Namespace patch. Big changes:
1. Nested classes are gone.
2. New syntax for namespaces:
namespace foo {
class X { ... }
function bar { ... }
var x = 1;

Namespace patch. Big changes:
1. Nested classes are gone.
2. New syntax for namespaces:
namespace foo {
class X { ... }
function bar { ... }
var x = 1;
const ZZ = 2;
}
3. Namespaced symbol access: $x = new foo::X; - etc.
For now, namespaces are case insensitive, just like classes.
Also, there can be no global class and namespace with the same name
(to avoid ambiguities in :: resolution).

Centralize class initialization

Rework static class properties - now supports access restrictions

Reimplement PPP properties

- Added some missing CVS $Id$ tags, headers and footers.

Revert commit which turned the lengths of strings into zend_uint.

RIP handle_* functions. ZE2 will use __ handlers instead.
# Yes, I know this will break some things. I will fix those I can find shortly.
