Adjust tests to be compatible with PHPUnit 10 (#998)

This avoids warnings on PHPUnit 10, without actually
switching to PHPUnit 10.

Add missing void return types (#997)

Allow passing visitors to NodeTraverser constructor

Add support for NodeVisitor::REPLACE_WITH_NULL

Fixes #716.

Call leaveNode() on visitors in reverse order

Node visitation is now properly nested. The call sequence will
now be

$visitor1->enterNode($n);
$visitor2->enterNode($n

Call leaveNode() on visitors in reverse order

Node visitation is now properly nested. The call sequence will
now be

$visitor1->enterNode($n);
$visitor2->enterNode($n);
$visitor2->leaveNode($n);
$visitor1->leaveNode($n);

rather than

$visitor1->enterNode($n);
$visitor2->enterNode($n);
$visitor1->leaveNode($n);
$visitor2->leaveNode($n);

Fixes #899.

Ensure removing visitor does not leave holes

Move constants from NodeTraverser to NodeVisitor

These are really part of the NodeVisitor API. Retain aliases for
compatibility.

Use PHPStan level 5

Support array return from enterNode()

This uses the same semantics as arrays from leaveNode(), i.e. the
returned nodes will not be visited by other visitors. This is open
to change t

Support array return from enterNode()

This uses the same semantics as arrays from leaveNode(), i.e. the
returned nodes will not be visited by other visitors. This is open
to change though (but probably should change for both enterNode()
and leaveNode() if it does change?)

Support REMOVE_NODE from enterNode()

Rename Scalar\LNumber to Scalar\Int_

Rename Scalar\DNumber to Scalar\Float_

Format tests as well

The unnecessary parentheses for "new" are a bit annoying, but I
can live with it...

Remove last uses of MockBuilder

Avoid most MockBuilder uses in NodeVisitor testing

This removes all the warnings about at() usage ... even though
it is still used. Apparently warnings don't get emitted if the
at()

at() usage is inside a data provider?
