Fix GH-11956: PCRE regular expressions with JIT enabled gives different result

The code in the attached test used to work correctly in PHP 8.0, but not
in 8.1+. This is because PHP 8.1+ uses a more modern version of pcre2
than PHP 8.0, and that pcre2 versions has a regression.

While upgrading pcre2lib seems to be only done for the master branch, it
is possible to backport upstream fixes to stable branches. This has been
already done in the past in for JIT regressions [1], so it is not
unprecedented.

We backport the upstream pcre2 fix [2].

Fix filter_var with callback and explicit REQUIRE_SCALAR

For some reason, FILTER_CALLBACK disables the FILTER_REQUIRE_SCALAR flag that is
normally set by default. While surprising, this is not something we can change.

However, even specifying FILTER_REQUIRE_SCALAR explicitly does not corrently set
this flag. This is because FILTER_CALLBACK zeroes the flags after they have been
populated from the parameters.

We reverse the checks to make explicitly specifying the flag behave as expected.

Fix GH-11878: SQLite3 callback functions cause a memory leak with a callable array

In this test file, the free_obj handler is called with a refcount of 2,
caused by the fact we do a GC_ADDREF() to increase its refcount while
its refcount is still 1 because the Foo object hasn't been destroyed yet
(due to the cycle caused by the sqlite function callback).
Solve this by introducing a get_gc handler.

Fix persistent procedural ODBC connections not getting closed

Like oci8, procedural ODBC uses an apply function on the hash list to
enumerate persistent connections and close the specific one. However,
this function take zvals, not resources. However, it was getting casted
as such, causing it to interpret the pointer incorrectly. This could
have caused other issues, but mostly manifested as failing to close the
connection even fi it matched.

The function now takes a zval and gets the resource from that. In
addition, it also removes the cast of the function pointer and moves
casting to the function body, to avoid possible confusion like this in
refactors again. It also cleans up style and uses constants in the
function body.

Fix GH-11972: RecursiveCallbackFilterIterator regression in 8.1.18

When you do an assignment between two zvals (no, not zval*), you copy
all fields. This includes the additional u2 data. So that means for
example the Z_NEXT index gets copied, which in some cases can therefore
cause a cycle in zend_hash lookups.
Instead of doing an assignment, we should be doing a ZVAL_COPY (or
ZVAL_COPY_VALUE for non-refcounting cases). This avoids copying u2.

clang and newer gcc releases support byte-sized atomic accesses on
riscv64 through inline builtins. In both cases the hard dependency on
libatomic added by GH-11321 isn't useful.

Stop using AC_CHECK_LIB() which is too naive to notice that libatomic
isn't needed. Instead, PHP_CHECK_FUNC() will retry the check with -latomic
if required.
