Add function to get the moves between two configurations
Add a function that, given two adjacent cluster configurations ofa balancing sequence, computes the moves that led from the firstto the second configuration.

In the list of involved nodes, drop "no secondary"
When grouping moves into jobs, a new job set is started, if the newmove involves a node also touched by a previous move. When computingthe list of involved nodes, the new primary and secondary nodes of the...
Merge 'EvacNode' and 'NodeEvacMode'
Merge 'EvacMode' and 'NodeEvacMode' which are associated with theduplicated constants 'IALLOCATOR_NEVAC_*' and 'NODE_EVAC_*'. Thismerge moves the type 'EvacMode' to 'Ganeti.Types' in order to avoid acircular dependency between 'Ganeti.HsConstants' and...

Support big-step shrinking in tiered allocation
In tiered allocation, if by shrinking only a single resource a validallocation can be found, shrinking is bound to shrink on this resource.Of course, after shrinking that resource a little bit without finding...
Index instances by their UUID
No longer index instances by their name but by their UUID in the clusterconfig. This change changes large parts of the code, as the followingadjustments were necessary: * Change the index key to UUID in the configuration and the...

In tiered allocation, cut non-promising shrinking tries
The heuristics for tiered allocation has been improved in that itchooses to shrink such a resource next where by shrinking only thisresource a valid allocation can be made, if such a resource exists....

Improve hspace shrinking strategy
In tired allocation, hspace shrinks that resource of the instancenext, that causes failure on most nodes. While, this is not a badstrategy in general, it can lead hspace into a dead end if for a largenumber of nodes a particular resource blocks any further allocation of...

hspace prints info about spindles
Statistics about spindles are tracked. In human-readable output, spindlesare printed only when used (i.e., exclusive storage is enabled). Formachine-oriented output, they are always there.

Check real spindles in ipolicies
When exclusive storage is enabled, the spindles in instance disks are usedto check the instance policies (as outlined in design-partitioned.rst).

Remove use of 'head' and add hlint warning for it
Since 'head' is unsafe to use in most cases, this patch removes itsuse from most of the code, adds a lint warning for it (and for tail aswell), and adds override annotations in the few cases where it'sactually OK to use it (mainly when using head over the result of...

Rename htools/ to src/
Per offline discussions, this is the first patch of therenames. Tested with "make distcheck", seems to work fine.
The only change outside of the renaming is a bit of simplification inthe .gitignore rules; otherwise, simply s/htools/src/....
