libudev: enumerate - sort with qsort()
On machines with many thousands of devices:
$ time find /sys -name uevent | wc -l
74876
real 0m33.171s
user 0m3.329s
sys 0m29.719s
the current udevtrigger spends minutes sorting the device list:
$ time /sbin/udevadm trigger --dry-run
real 4m56.739s
user 4m45.743s
sys 0m7.862s
with qsort() it looks better:
$ time udev/udevadm trigger --dry-run
real 0m6.495s
user 0m0.473s
sys 0m5.923s
