[oe] bitbake fetch vs fetchall?

[Chris Larson]

'fetch' fetches for the one recipe you're requesting.  If you bitbake -c
fetch busybox, it fetches busybox.  If you bitbake -c fetchall busybox, it
fetches busybox and all of busybox's dependencies.  This is the case for all
the tasks which end in 'all'.
