KestrelHPC Svn

[FIXED] list_users() didn't list correctly the users: from the second name it only created a single comma separated list.

share/default.conf:
- Extracted some variables from default.conf like those related to kestrel dirs into an internal config file.

kestrel-lib:
- Splitted into:
- reconfigure-lib: Reconfiguration functions.
- node-status-lib: Node status functions.
- check_kestrel_daemon:
- Detects if kestrel is enabled
- Improved the failure messages
- New msg and warning functions
- New kestrel_dialog function

Note: This is an quite unstable and partial commit, part of a big refactoring.

kestrel-daemon:
- Set VERBOSE flag
- Use KESTREL_RPC_FIFO variable
- Use new node-status-lib (refactored from kestrel-lib)

kestrel-reconfigure:
- Added os detection when enabling KestrelHPC. Saves OS_* variables in ${KESTREL_SHARE}/default.d/internal_detected_os
- Added missed check_root

debian/control:
- Add lsb-release as a dependency

share/kestrel-lib
share/defaults-lib
- Fixed issue with list_users. Reported by Nathan Gosset.
- Moved RE definitions to defaults-lib from kestrel-lib
- Moved detect_ifca to defaults-lib from kestrel-lib

init.d/kestrel_daemon:
- Use detect_iface function to check if there is a network interface set up with the configure frontend ip

share/frontend/install.d/chromium-gl
- Deleted, unnecesary on chromium-opengl-* (1.9-1ubuntu11)
