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.
htools cluster score takes spindles into account
When exclusive storage is enabled, spindles are used instead of disk spaceto compute the cluster score.
Comments and variable names in computePDsk has been changed to match theactual code.
Update spindles when moving instances in htools
Spindles get updated, and errors raised when not enough free spindlesexist. No new error is raised when exclusive storage is disabled.
Unit tests included.
Load node spindles data in htools
The data structure for nodes gets a new field for free spindles, and theexisting field for total spindles gets renamed to avoid identifying it withthe node parameter that had the same name. These fields get filled with...

Support construction of the graph of all reboot constraints
For online rolling reboots, there are two kind of restrictions. First,we cannot reboot the primary and secondary nodes of an instancetogether. Secondly, two nodes cannot be rebooted simultaneously, if...
Extend the Node in the htools to allow adding node tags
Since hroller (and probably other tools in the future) will supportnode selection based on node tags, extend the node data structure toallow adding this information.

Make mkNodeGraph ignore edges to non-present nodes
Change the behavior of mkNodeGraph to tacitly ignore all instanceswhere one of the nodes is not in the list of nodes. In this way, wecan construct sub-graphs by filtering the nodes and ignoring anypossibly added isolated nodes for the missing indexes....
Extend the node description by isMaster
Extend the description of the node by the propertyof being the master node; also provide and appropriatesetter function. This property will be used, e.g., byhroller to schedule reboot of the master last.
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/....
