Cristiano Giuffrida 6f912993ff Share exec images in RS.
RS CHANGES:
- RS retains information on both labels and process names now. Labels for boot
processes are configured in the boot image priv table. Process names are
inherited from the in-kernel boot image table.
- When RS_REUSE is specified in do_up, RS looks for an existing slot having the
same process name as the one we are about to start. If one is found with
an in-memory copy of its executable image, the image is then shared between
the two processes, rather than copying it again. This behavior can be specified
by using 'service -r' when starting a system service from the command line.
