Fix for challenge string length pointed out by Kalle Nielsen
Fix #64780 (PHP 5.5 builds are broken with GCC 3)

A recent change (by me) introduced a call to __builtin_offsetof()
into zend_operators.h which is not defined by GCC prior to
version 4.

Changed the code to use offsetof() instead: this is defined in
<stddef.h>, so #include this header conditionally (#ifdef GNUC)

Fixed bug #64769 mbstring PHPTs crash on Windows x64

The tricky business going there in oniguruma is saving a pointer
in an int variable, passing that variable into a function and making
it a pointer again. On 64bit windows casting a pointer to a 32 bit
int will truncate that pointer. This kind of things won't work on
Windows x64.

[SNIPPET]
unsigned long ul0[2], ul1, *ul2;

ul0[0] = 42uL;
ul0[0] = 24uL;

ul1 = (unsigned long)ul0;
ul2 = (unsigned long *)ul1;

/* now it's broken, accessing ul2[0] will crash. */
[/SNIPPET]

To make it portable, ULONG_PTR should be used in this case.

In oniguruma this behaviour is to see at least in the following
codepath:

ext/mbstring/oniguruma/enc/unicode.c:10938
ext/mbstring/oniguruma/st.c:308
ext/mbstring/oniguruma/enc/unicode.c:10859

Fixed bug #64821 Custom Exceptions crash when internal properties overridden

If user inherits Exception and overrides the properties to arbitrary data types,
or simply doesn't run parent::__construct(), here we go. Just convert everything
to the appropriate data type, like Exception::__toString() does.
