Review request for Plasma and Solid.


Repository: plasma-workspace


Description
-------

An attempt to implement feature from [bug 96107](https://bugs.kde.org/show_bug.cgi?id=96107) (see summary).

On umount/eject error it runs "lsof" executable, gets PIDs of blocking processes and obtains names of processes via KSysGuard::Process machinery. Finally it appends obtained information to error message which is shown in tooltip of Device Notifier applet.

Testing
-------

Tested unmount on busy device with several processes blocking it. Did not test eject, since I have no optical disc drive :(
