Avoid unnecessary reference-counting on strings.

RC manipulation cleanup

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.

Allow internal functions to return values by reference (this was disabled in implementation of DO_ICALL, but enabled in DO_FCALL).
However, don't require internal functions returning by reference to return a reference.
Mark unserialize() as returning by reference and remove unwrap_reference hack, to allow proper returning of self referenced arrays using a reference.
Currently unserialize() is the only internal function that may return a reference.

Always use IS_CONSTANT_AST (IS_CONSTANT is removed).

This patch however does not drop support for the BeOS compatible variant, Haiku, see Github PR #2697 which is currently a WiP

I intentionally left out some fragments for BeOS in the build system for that seems to be bundles

Kill compiler warnings in ext/standard

remove casts

move zend_ato*() to size_t and remove casts

Only compute callback name in error cases

Mostly the callback name is only used to report an error. Try to
avoid calculating it if no error occurred.

Avoid useless dereferences and separations during paramter passing.

Fixes bug #74708 reflection signatures for random_bytes+random_int

They have 1 and 2 required parameters, respectively
See https://secure.php.net/manual/en/function.random-int.php

Use interned empty and "one char" strings.

Fix bug #74409

Don't retain mt_rand() seeds across requests

In particular, this prevents manual seeding of mt_rand() to leak
across requests.

Return FALSE if error_log fails to write all bytes
