changes:
- enable extras, this includes pci/usb and acl related utilities
- pci.ids automatic search doesn't work, specifying manually
- package udev glib binding into libgudev{,-dev,-dbg}
- libudev RDEPENDS on udev, this is somehow counter-intuitive:
libudev is the library to access udev information
- should RRECOMMENDS usbutils-ids and pciutils-ids
bug: RDEPENDS (RRECOMMENDS) on a specific version still doesn't work
