Show a % when a volume is loaded in a drive.

For a status slots print a % when the volume is loaded into
a drive.

'@' - import export slot
'*' - data in backup catalog doesn't match
'%' - volume is loaded into a drive.
' ' - nothing special with volume just in slot and catalog info matches.

Add running jobs scheduled time in director status

Make compression context part of generic JCR.
Don't needlessly link binaries to compression libs.

When we link the compression libaries into the shared library

use dynamic linking. When you want static linking then you do
need to specify the compress libraries needed also for the
binary as it copies the object code into your binary.
