Trevor Woerner 6ddb9bc4bb psplash (sysvinit): add textual updates

The psplash program contains a hidden text box immediately above the
progress bar. Any text sent via a "MSG" command through psplash's fifo will
be displayed, centred, above the progress bar. Add the ability to show
which startup script is currently running, in sync with updates to the
progress bar. If a startup script takes a bit longer than others and the
progress bar stops momentarily, this allows the user to know which script
is responsible.

This feature is added with a knob, default off, for enabling or disabling
this feature. The knob is in the form of a PACKAGECONFIG against the
sysvinit recipe: psplash-text-updates

NOTE: this knob can be changed in the filesystem at runtime by editing
/etc/default/rcS regardless of how it is set in the build.
