Fix uouv in array_column

column_long and index_long might not be set, but are still used as arguments.
They are not actually used if column_str is set, but it's better to initialize
them anyway, if only to make MemorySanitizer happy.

Avoid crash for reset/end/next/prev() on ffi classes (#9711)

(And any PECLs returning `zend_empty_array` in the handler->get_properties
overrides)

Closes GH-9697

This is similar to the fix used in d9651a941915eb5fb5ad557090b65256fd8509b6
for array_walk.

This should make it safer for php-src (and PECLs, long-term) to return
the empty immutable array in `handler->get_properties` to avoid wasting memory.
See https://github.com/php/php-src/issues/9697#issuecomment-1273613175

The only possible internal iterator position for the empty array is at the end
of the empty array (nInternalPointer=0).
The `zend_hash*del*` helpers will always set nInternalPointer to 0 when an
array becomes empty,
regardless of previous insertions/deletions/updates to the array.

Fix GH-9296: `ksort` behaves incorrectly on arrays with mixed keys

The comparator function used at ksort in SORT_REGULAR mode
need to be consistent with basic comparison rules. These rules
were changed in PHP-8.0 for numeric strings, but comparator
used at ksort kept the old behaviour. It leads to inconsistent
situations, when after ksort the first key is GREATER than some
of the next ones by according to the basic comparison operators.

Closes GH-9293.

Fix GH-9244: Segfault with array_multisort + array_shift

After restructuring non-packed arrays, we either need to pack them if
possible, or to rehash them.

Closes GH-9247.

Avoid unnecessary comparison

The first element of the `arrays` serves as base for the comparison, so
there is no need to compare it to itself.

Closes GH-9246.

Remove `->last_unsafe` from php_random_status (#9132)

Whenever ->last_unsafe is set to `true` an exception has been thrown. Thus we
can replace the check for `->last_unsafe` with a check for `EG(exception)`
which is a much more natural way to ommunicate an error up the chain.
