The cake traffic-shaper qdisc omne stop solution knows how to handle
link layer adjustments for ATM and can account for per packet overhead.
This commit adds cake as link layer adjustment mechanism in the GUI and
passes numerically specified overhead as well as the ATM linklayer
keywords on to cake. This change also passes the "advanced option strings"
from the Queue Discipline tab to cake. But as before no error checking.
This needs testing, as I have no working cake qdisc available so
caveat emptor...

Make clear that configuration options guarded by checkboxes are only
effective as long as those boxes are checked.
The sqm gui has giarded some advanced configuration options behind exposing
checkboxes, meaning these optiopn's values were only used as long
as those boxes were checked. This commit just improves the description of
the checkboxes to included this useage instruction...

The SQM gui has confused its users with an enable button, that only served to
selecively activate/de-activate sqm instances instead of controlling sqm's
initscript (which needs to be enabled so the sqm properly starts up after a reboot
and also for hotplug to work properly). luci-app-sqm will now enable sqm's
initscript when a single sqm instance get enabled. It also informs the user about
this fact in the top margin of the sqm page. Note sqm will not disable the
initscript behind the user's back if sqm instances get disabled.
While I would have prefered this notice to be more prominent an attentive user
should notice, and most users should not care anyway. This also increases the
package release number.

sqm-scripts for a long time interprets a "Down- or Upload speed" of zero as
an indication that the shaper should be disabled. Note that really shaping
an individual direction down o zero will make the link effectively dead
for tcp (think reverse ACK traffic). Son instead of allowing the user to
configure something broken, 0 was "over-loaded" to denote no shaping
since several years, but that information has not been documented visibly
to the users. This commit aims at fixing that oversight.

Alan Jenkins noted a bug in the smq luci GUI that effectively
erased several configuration paramters if two checkboxes were deselected.
This behaviour seems consistent in luci but certainly has the potential
to confuse users. While confusion can not really be avoided generally
it seems wise to change the default interpretation for empty or non-existent
itarget and etarget variables from the qdisc's default (5ms in the case of
one of the codels) to automatic determination of tghis variable dependent on
the configured bandwidth, as codels target variable should be large enough
to contain at least one full packet. With this change sqm-scripts will
do the right thing by default, but will yet allow the user to specify
over-ridding values (as long as the user does not un-check the
entry-field exposing check boxes). Survives light testing...
This change set also changes the sqm-scripts luci gui to note the user
of the change. For compatibility with existing setups sqm-scripts
will still honor "auto" as an alternative explicit way of requesting
automatic target selection. This might turn into a warning in the future
and might be phased out...
