SLES resync

Hi Christophe,

here as some patches which accumulated in my SLES repository. Most are plain bugfixes, but there are some nasty issues fixed with this:
- The conversion to libudev was a bit overzealous; originally we'd be skipping all devices which don't have a SCSI ID. With libudev we'd be including even those, making multipath claiming even USB flash disks :-(
So I've implemented a new 'property' blacklist which will allow us to blacklist devices based on the udev property.
- dev_loss_tmo setting continues to be tricky, but this time I think we've got it sorted
- When using libudev to read attribute variables we'd be getting an automated caching from libudev. Which is nice, unless the data changed in between. So I'd have to go back an roll our own accessors, skipping libudev here.
- Ripping out 'getuid_callout' rendered all old configuration files still using in unworkable. So I've re-introduced it by marked it 'obsolete'.

As usual, comments etc are welcome.
