PROBLEM: (90279) (PATCH ID: OSF520-784)
********
This patch fixes and improves the mcutil program by correcting how 
bus resets are handled by the program and enhancing its error reporting 
capailities.
The problem with the mcutil program is that if a bus reset occures before
a command is issued to a tape library, the device open call will fail, 
resulting in an "unknown error" reported to the program.

Reporting most errors as "unknown" is incorrect  as the unix error values 
returned from the changer driver are well defined. The mcutil program simply 
is not mapping error strings for the possible errors returned from the 
changer driver.
