Returning anything else but NULL would suggest the caller's reference
might still be valid, but it isn't, because the caller just invoked
_unref() after all.
This turns the return value into a typesafe shortcut that allows
unreffing and resetting a reference in one line. In contrast to
solutions for this which take a pointer to a pointer to accomplish the
same this solution is just syntactic sugar the developer can make use of
but doesn't have to, and this is particularly useful when immediately
unreffing objects returned by function calls.

This extends 62678ded 'efi: never call qsort on potentially
NULL arrays' to all other places where qsort is used and it
is not obvious that the count is non-zero.

At the beginning move_later is set to -1, but it is set to different
value only if expression !move_later is true.

udev_device_get_subsystem() may return NULL if no subsystem could be
figured out by libudev. This might be due to OOM or if the device
disconnected between the udev_device_new() call and
udev_device_get_subsystem(). Therefore, we need to handle subsystem==NULL
safely.
Instead of testing for it in each helper, we treat subsystem==NULL as
empty subsystem in match_subsystem().
Backtrace of udev_enumerate with an input-device disconnecting in exactly
this time-frame:

We need to free udev-devices again if they don't match. Funny that no-one
noticed it yet since valgrind is quite verbose about it.
Fix it and free non-matching devices.

If a realloc() happens in syspath_add(), the move_later pointer could
point to an invalid memory region.
Let move_later store the array index, instead of the pointer to the
entry.
