Carry error status in printer list IPC message

[David Disseldorp]

Hi,

Currently the process forked to fetch printcap information from cups
does not include error status in its IPC message back to the parent.
As a result the parent is unable to differentiate between an empty
printer list and a failure to obtain the information from cups.

This patch-set converts the IPC message to an IDL defined format, which
includes the error status alongside the list of printers.

Cheers, David
