Replace LD_* constants with DT_* constants

LD_* constants are basically like DT_* constants, except
for that both file and shared file were mapped to file.
In order to not having to maintain three slightly different
sets of disk-related constants (DT, LD and ST), we merge...

Index nodes by their UUID

No longer index nodes by their name but by their UUID in the cluster

hv_xen.py: make hvparams mandatory, remove fallbacks

This patch removes the fallback to the xen command from the
auto config and adds an exception instead. Also, the

Some methods still refered to 'xm', which is inaccurate now
that xen can also be run with 'xl'. No functional changes
otherwise.

Verify: xen toolstack, hypervisor and hvparams

This patch extends the node verification by:
- Adding a check for the xen toolstack when the hypervisor

hv_xen.py: rename GetXmList to GetInstanceList

Since one can retrieve xen's instance list via both 'xm'
or 'xl', it is no longer appropriate to call the function
'GetXmList'. This patch renames it to 'GetInstanceList'.
Other than that, there are no functional changes....

Unit tests for hv_xen._GetCommand

This patch adds unit tests for the current state of the
'GetCommand' method. The tests are rather trivial, but
having tests before starting to refactor seems to be
a good idea.

Stash Xen config file after a failed startup

This is a fix for a minor bug.
Currently, a failed Xen VM start results in a stale config file left
behind on the filesystem.
This change introduces a new log directory, where the Xen VM config
file is moved after a failed startup....
