- Fixed bug #80998 (Missing second with inverted interval).
- Speed up finding timezone offset information.

BP_VAR_UNSET should not result in undefined warnings.

This is relevant wrt. case insensitive identifiers.

Closes GH-7391.

We need to run the full `php_cli_server_request_shutdown()` in case of
failing `php_cli_server_request_startup()`.

Patch contributed by @cataphract.

Closes GH-7322.

Normally the filename is the current filename, but when traits
are involved, it might be a different one.

Add a new interned string handler that fetches an interned string
if it exists, but does not create one if it does not (and instead
returns a non-interned string).

This fixes bug #81142, by preventing the creating of new interned
strings for unserialized array keys.

Closes GH-7360.

S->cols is already freed in the statement destructor and since
caa7100 the column data is only
populated on the first execute() which means that on subsequent
execute()s after closeCursor was called, all meta-data for column types
was removed and never restored

Closes GH-7355.

The ascii to wchar was reporting errors using conv_illegal_output,
while it should have been using WCSGROUP_THROUGH. Effectively that
replaced illegal characters with '?' for the purpose of
identification.

Allow arbitrary whitespace, not just horizontal spaces.

Fixes:
- Bug #80998 (Missing second with inverted interval). (Derick)
- Bug #81106 (Regression in 8.1: add() now truncate ->f). (Derick)

Fixes among others:
. Bug #79580 (date_create_from_format misses leap year).
. Bug #80974 (Wrong diff between 2 dates in different timezones).
. Bug #81097 (DateTimeZone silently falls back to UTC when providing an offset with seconds).
. Bug #81273 (Date interval calculation not correct).

Creation of the filter may fail for some special encodings, for
which detection is not supported.

Use ZEND_MM_ALIGNED_SIZE for the extra size information.
I don't have a relevant system to test, but this should fix the
issue as long as required alignment is detected correctly.

This has also been fixed by 3eb97a4.

When running without opcache, static_members_table is shared with
default_static_members_table. This is visible in reflection output,
because ReflectionProperty::getDefaultValue() will return the
current value, rather than the default value.

Address this by never sharing the table, which matches the behavior
we already see under opcache.

Fixes bug #80821.

Closes GH-7299.

* PHP-8.0:
  Fixed Bug #80959 (infinite loop in building cfg during JIT compilation)

* PHP-8.0:
  Fixed Bug #81255 (Memory leak in PHPUnit with functional JIT)

The empty array has refcount > 1, so we should indicate this in
func info. In most cases this renders the func info redundant,
so drop it entirely.

…with JIT)

* PHP-7.4:
  Revert "Fix #79908: json_encode encodes negative zero as int"
