Fix #78650: new COM Crash

As of PHP 7.4.0, the `get_property_ptr_ptr` handler is mandatory; we
implement it to always return `NULL`, which is equivalent to not
setting the handler in former versions.

We add a portable and faster test case than what has been presented in
the bug ticket.

Comparison cleanup:

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

Don't set nullability flag for parameters without type

Use value 0 instead. To compensate we check in ReflectionParameter
allowsNull() whether the type is set at all: If it isn't, it always
allows null.

This removes a discrepancy between internal&userland functions:
For userland functions allowsNull() on untyped parameters returned
true, but for internal functions it returned false.

Change representation of zend_type from type code to MAY_BE_* mask

Change representation of zend_type from type code to MAY_BE_* mask

This switches zend_type from storing a single IS_* type code to
storing a MAY_BE_* type mask. Right now most code still assumes
that there is only a single type in the mask (or two together
with MAY_BE_NULL). But this will make it a lot simpler to introduce
union types.

An additional advantage (and why I'm doing this separately), is
that a number of special cases no longer need to be handled
separately: We can do a single mask & (1 << type) check to handle
all simple types, booleans (true|false) and null.

Remove get() object handler

Now that set() is gone, there is little point in keeping get(), as
it is essentially just a different way of writing cast_object()
now.

Firstly, we avoid returning NULL from the get_property handler, but
instead return an empty HashTable, which already prevents the crashes.
Secondly, since (de-)serialization obviously makes no sense for COM,
DOTNET and VARIANT objects (at least with the current implementation),
we prohibit it right away.

Remove unused Git attributes ident

The $Id$ keywords were used in Subversion where they can be substituted
with filename, last revision number change, last changed date, and last
user who changed it.

In Git this functionality is different and can be done with Git attribute
ident. These need to be defined manually for each file in the
.gitattributes file and are afterwards replaced with 40-character
hexadecimal blob object name which is based only on the particular file
contents.

This patch simplifies handling of $Id$ keywords by removing them since
they are not used anymore.
