bd4fce4f6f Fixed bug #78986 
Don't assume that handlers live in the arena, they may also be in
SHM.

0f2cdbf214 Introduce extra counter to avoid RTD key collisions 
Also generate a fatal error if a collision occurs in zend_compile.

This is not perfect, because collisions might still be introduced
via opcache, if one file is included multiple times during a request,
invalidate in the meantime and recompiled by different processes.

This still needs to be addressed, but this patch fixes the much
more common case of collisions occuring when opcache is not used.

Fixes bug #78903.

f1848a4b3f Fix bug #78226: Don't call __set() on uninitialized typed properties 
Assigning to an uninitialized typed property will no longer trigger
a call to __set(). However, calls to __set() are still triggered if
the property is explicitly unset().

This gives us both the behavior people generally expect, and still
allows ORMs to do lazy initialization by unsetting properties.

For PHP 8, we should fine a way to forbid unsetting of declared
properties entirely, and provide a different way to achieve lazy
initialization.

bebcdcc745 Remove legacy AC_CHECK_TYPE calls for uint and ulong 
The AC_CHECK_TYPE was refactored in more recent versions of Autoconf
and the call with two arguments is obsolete and not recommended anymore.

This patch also refactors some leftovers of using ulong and uint which
are not standard nor common usages of types in C.

The ulong can be used as zend_ulong and uint usage is actually
`unsigned int`.

The usage of HAVE_ULONG removed since it is not used in current code
base.

Legacy edgecase for some legacy HPUX systems removed:
- sys/stream.h header is not checked and the HAVE_SYS_STREAM_H is
  not defined with current build system.

- flags are unsigned int
- max_allowed_packet changed to unsigned int

2543e61aed Fixed bug #76509 
In PHP static properties are shared between inheriting classes,
unless they are explicitly overwritten. However, because this
functionality was implemented using reference, it was possible
to break the implementation by reassigning the static property
reference.

This is fixed by switching the implementation from using references
to using INDIRECTs, which cannot be affected by userland code.
