add support for AF_UNIX SOCK_DGRAM

[GoogleCodeExporter]

This is needed to write to syslog (/dev/log).

Just try to open socket as SOCK_STREAM, and if it fail then try again as 
SOCK_DGRAM.

People adding things to Unix later never really quite understood 
device-independent IO, did they?

i've also included a change to allow implementation of osdisksize, so that stat 
of a (host) device file representing a disk can return its length (size). 
usually the host systems require the file to be open for reading, so it's not 
as helpful as i'd like, but does allow disk/fdisk and disk/prep to run on (say) 
user-writable usb drives.
