0061db5503 Fix #77291: magic methods inherited from a trait may be ignored 
When adding methods from a trait, we must not assume that a method name
with the same length as the name of the using class is either a PHP 4
style constructor, or not a magic method at all – it may well be
another magic method.

We mostly preserve the spirit of the optimization which caused this
regression, and avoid string comparisons for all method names which can
never be magic methods.

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.

b4dff68379 Remove no longer necessary type-name special cases 
zend_get_type_by_name() now produces the correct value by itself,
so we no longer need these workarounds.

fcc08ce19f Prevent reference-counting on persistent zvals (internal constants, default properties and constants of internal classes). 
New macro ZVAL_COPY_OR_DUP() is used perform duplication, if necessary.
This should eliminate related race-coditions in ZTS build and prevent reference-counting bugs after unclean shutdown.

49ea143bbd Encapsulate reference-counting primitives. 
Prohibit direct update of GC_REFCOUNT(), GC_SET_REFCOUNT(), GC_ADDREF() and GC_DELREF() shoukf be instead.
Added mactros to validate reference-counting (disabled for now).
These macros are going to be used to eliminate race-condintions during reference-counting on data shared between threads.
