Summary issue for bug 2273 #12

This issue is intended as a meta issue for tracking problems related to bug 2273.

Individual problems will be described in other issues and add as dependency to this one.

Depends on following issues:

TDE/tdelibs#30 - this turned out to be an invalid issue
TDE/tdelibs#31 - dm plain disks won't be supported from GUI
TDE/tdelibs#32

Overview or additional required changes:

code individual device operation in tdestoragedevice (mount, unmount, lock, unlock) based on udisks2 dbus calls
udisks has been replaced by udisks2 and not available in many distros, so no support for udisks will be added
udevil does not support unlock/lock operations (only mount/unmount) so it is not possible to add support for unlocking /locking with udevil
consider adding support for pmount
~~add HAL-based support if possible (support is partial due to limitations in HAL)~~ HAL support in TDE will be removed in R14.1.0.
polkit GUI authentication agent to allow normal user to authenticate to perform some of the actions
bug fixes from TODO list

Required PRs are listed here:

Supported added in several commits.
