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).
These are deprecated in favor of date()/DateTime::format() (for
locale-indendent formatting) and IntlDateFormatter::format()
(for locale-dependent formatting).

This deprecates passing null to non-nullable scale arguments of
internal functions, with the eventual goal of making the behavior
consistent with userland functions, where null is never accepted
for non-nullable arguments.
This change is expected to cause quite a lot of fallout. In most
cases, calling code should be adjusted to avoid passing null. In
some cases, PHP should be adjusted to make some function arguments
nullable. I have already fixed a number of functions before landing
this, but feel free to file a bug if you encounter a function that
doesn't accept null, but probably should. (The rule of thumb for
this to be applicable is that the function must have special behavior
for 0 or "", which is distinct from the natural behavior of the
parameter.)

Closes GH-6475.
* Remove usage of strftime() in favor of date() in cases where
we are not specifically testing strftime(). We implement
date() ourselves, and as such are insulated from implementation-
defined behavior.
* Add skipif for broken strftime() %Z support. We have decided
not to work around the issue for musl using manual expansion,
as people should not be using this function anyway, and it is
slated for future deprecation.
* Don't test strftime() with invalid format specifier. The
behavior is implementation-dependent.
Also fixes similar issues for DateTimeImmutable::createFromFormat,
DateTime::createFromImmmutable, DateTime::createFromInterface,
DateTimeImmutable::createFromMutable, and
DateTimeImmutable::createFromInterface.
Userland classes that implement Traversable must do so either
through Iterator or IteratorAggregate. The same requirement does
not exist for internal classes: They can implement the internal
get_iterator mechanism, without exposing either the Iterator or
IteratorAggregate APIs. This makes them usable in get_iterator(),
but incompatible with any Iterator based APIs.
A lot of internal classes do this, because exposing the userland
APIs is simply a lot of work. This patch alleviates this issue by
providing a generic InternalIterator class, which acts as an
adapater between get_iterator and Iterator, and can be easily
used by many internal classes. At the same time, we extend the
requirement that Traversable implies Iterator or IteratorAggregate
to internal classes as well.
Closes GH-5216.
