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.

refactor: change `zend_is_true` to return `bool` (#14301)

Previously this returned `int`. Many functions actually take advantage
of the fact this returns exactly 0 or 1. For instance,
`main/streams/xp_socket.c` does:

sockopts |= STREAM_SOCKOP_IPV6_V6ONLY_ENABLED * zend_is_true(tmpzval);

And `Zend/zend_compile.c` does:

child = &ast->child[2 - zend_is_true(zend_ast_get_zval(ast->child[0]))];

I changed a few places trivially from `int` to `bool`, but there are
still many places such as the object handlers which return `int` that
should eventually be `bool`.

random: Pass algorithm and state together as `php_random_algo_with_state` (#13350)

* random: Remove `php_random_status`

Since 162e1dce9870168cb8c65c013f2b5a510b6536b1, the `php_random_status` struct
contains just a single `void*`, resulting in needless indirection when
accessing the engine state and thus decreasing readability because of the
additional non-meaningful `->state` references / the local helper variables.

There is also a small, but measurable performance benefit:

<?php
$e = new Random\Engine\Xoshiro256StarStar(0);
$r = new Random\Randomizer($e);

for ($i = 0; $i < 15; $i++)
var_dump(strlen($r->getBytes(100000000)));

goes from roughly 3.85s down to 3.60s.

The names of the `status` variables have not yet been touched to keep the diff
small. They will be renamed to the more appropriate `state` in a follow-up
cleanup commit.

* Introduce `php_random_algo_with_state`

Fix instable array during in-place modification in uksort

The array isn't just observable if the array has RCn, but also if it is inside a
reference that is RCn. By-ref parameters are always RCn and as such always
observable.

Fix iterator position resetting

Previously, when an array was converted from packed to hashed, iterators would
not be correctly reset to 0. Similarly, removing the last element from an array
would decrease nNumUsed but not actually fix the iterator position, causing the
element to be skipped in the next iteration.

Some code was also removed that skips over IS_UNDEF elements for
nInternalPointer and iterator positions. This is unnecessary, as this already
happens during iteration.

Fix GH-13094: range(9.9, '0') causes segmentation fault

`start_type + end_type < 2*IS_STRING` is not right, in this test case
the types are start_type==5 (IS_DOUBLE), end_type==7 (IS_ARRAY).
The IS_ARRAY type is a sentinel to disambiguate single-byte strings.
The path must be taken when one of the types is not a string nor a
single-byte string. Therefore, use < IS_STRING with an OR condition.

Closes GH-13105.
