Fix leak in DateTimeImmutable::modify()

Fix leak in DatePeriod construction with invalid format

Same issue as I fixed in DateInterval construction before.

Fix rel_date leak on DateInterval construction failure

Make error messages more consistent by fixing capitalization

Closes GH-5066 As a first step, let's capitalize their initial letter when it is applicable.

Adding DateTime(Immutable)::createFromInterface()

These are like

DateTime::createFromImmutable()
DateTimeImmutable::createFromMutable()

but accept any DateTimeI

Adding DateTime(Immutable)::createFromInterface()

These are like

DateTime::createFromImmutable()
DateTimeImmutable::createFromMutable()

but accept any DateTimeInterface instead.

Closes GH-5016.

Fix #79015: undefined-behavior in php_date.c

We check that the given microsecond fraction is in the valid range
[0, 1000000[, and otherwise mark it as invalid. We also drop the
useless do loop; a plain block is sufficient here.

Use RETURN_THROWS() after zend_parse_method_parameters()

Use RETURN_THROWS() after zend_throw_error()

Use RETURN_THROWS() during ZPP in the date, dba and dom extensions

Support single class unions in gen stubs

Fix DateTimeImmutable stubs

These were referencing the arginfo from the functions, instead of
the methods, which isn't right, as the functions have return types.

Add missing ZPP checks

Closes GH-4878.

Cleanup return values when parameter parsing is unsuccessful

Add Z_PARAM_STRING/ARRAY_OR_NULL convenience macros

Fix #78751: Serialising DatePeriod converts DateTimeImmutable

When getting the properties of a DatePeriod instance we have to retain
the proper classes, and when restoring a DatePeriod instance we have to
cater to DateTimeImmutable instances as well.

Fix #70153 \DateInterval incorrectly unserialized

Added a separate macro for reading 'days' property, so that bool(false)
is correctly converted to the proper internal representation.

Comparison cleanup:

- introduce zend_compare() that returns -1,0,1 dirctly (without intermediate zval)
- remove compare_objects() object handler, and keep only compare() handler

Remove most uses of ZEND_PARSE_PARAMETERS_END_EX()

As ZPP now throws, it makes no sense to specify an explicit return
value.

Remove mention of PHP major version in Copyright headers

Closes GH-4732.

Fix typo

`sizeof("data")-1` and `sizeof("date")-1` are both 4, so no change in behaviour

Update the date class arginfo the new format

Make uninitialized DateTime an Error

This avoids many spurious false return values.

Generate arginfo from PHP stub files

Signature stubs for internal functions are specified in xyz.stub.php,
from which we generate actual arginfo structures in xyz_arginfo.h.

Generate arginfo from PHP stub files

Signature stubs for internal functions are specified in xyz.stub.php,
from which we generate actual arginfo structures in xyz_arginfo.h.
This file then needs to be included in the implementation appropriately.

Arginfo from stubs can be regenerated using scripts/dev/gen_stub.php.
However, this should also automatically happen when the stub file is
modified.

Fix #65547: Default value for sunrise/sunset zenith still wrong

The value of the zenith angle to calculate sunrise and sunset times is
commonly defined as 90°50', and is "obtained by adding the average
apparent radius of the Sun (16') to the average amount of atmospheric
refraction at the horizon (34')", according to
http://aa.usno.navy.mil/faq/docs/RST_defs.php.

This value is also used for the Sunrise/Sunset Algorithm published in
the Almanac for Computers, 1990, see
