Description:
------------
As all but the first parameter of mkdir are optional and non sequential, it makes sense to be able to pass NULL to each if a later param is required.

E.g. mkdir('some/path/foobar', null, true);

Reproduce code:

This patch adds this functionality:

I fail to see why `NULL` would be preferable to the more explicit
`0777` here.  IMHO: won't fix.

As of PHP 8.0.0 you can use named arguments[1], what seems to be a
good alternative to your suggestion.  If you still feel that there
should be a way to skip default parameters without using named
arguments, please raise that on the internals mailing list[2],
since this would need discussion and an RFC[3].
