Nikita Popov b10416a652 Deprecate passing null to non-nullable arg of internal function
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.

<?PHP
class cat {

}
}
$cat = new cat();
$cat->show_output('Files: ', trim((string) `cd .`)); // this gives invalid args to shell_exec
$cat->show_output('Files: ', `cd .`); // this causes a segmentation fault
