Support of RoutingGauge, part 2.
In Katabatic & Kite, remove all hard-coded values related to track pitches.
* New: In <Session>, add more convenience function to access RoutingGauge
characteristics.
* New: In <AutoSegment>, <AutoContact>, add support for the "depth spin",
that is, if the source/target contacts are going "top" or "down".
Used to compute the perpandicular pitch. Need a small modification
of the revalidation mechanism. The observers of <AutoSegment> are
notified when the spin changes.
* New: In <AutoSegment>, the getPPitch() method allow to compute the
"perpandicular pitch". For now it is simply the greatest from the
source perpandicular pitch and the target perpandicular pitch.
Make uses of the "depth spin".
* New: In <TrackElement>, <TrackSegment>, cache the perpandicular pitch.
Updated through the notification from the observable.

bool TrackElement::isSameLayerDogleg () const { return false; }

Implementation of pre-routing support (for clock-tree compliance).
* New: In Katabatic, in <AutoContact>, this class is no longer derived
from ExtentionGo. With the simplificated AutoContacts, there is no
reason to do so, and it will save some QuadTree insertions/deletions.
New factory function AutoContact::createFrom(Contact*) which try to
build an AutoContact on top of a Hurricane::Contact. Of course that
base contact *must fit* into one of the predefined Contact
configurations (Terminal, Turn, HTee or VTee).
NOTE: This implies that the pre-routed segments & contacts *are*
correctly articulated, which is not the case when a Cell is read
from disk in "ap" format. The pre-routing feature must be used for
now without any re-read from disk. We will implement a re-articulating
pre-process in the future.
* Change: In Katabatic, in <AutoContact> derived classes, the ::updateCache()
method now display an accurate error message if a segment is connected
but has no AutoSegment conterpart (i.e. the lookup fails).
* New: In Katabatic, in <AutoSegment>, the ::computeOptimal() method is
short-circuited for pre-routed segments, the optimal axis position is
considered to be the one it is currently on (i.e. we trust the designer).
* New: In Katabatic, in <KatabaticEngine>, the ::loadGlobalRouting()
method now accept a map of excluded nets (same as Knik). This map is
the one of pre-routed nets.
* New: In Katabatic, in layer assignment, do not try to displace fixed
segments...
* New: In Katabatic, in <AutoSegment>, new flag SegUserDefined and related
methods to know if a segment comes from the global router (Knik) or
is pre-routed (supplied by the user).
* New: In Kite, In <BuildPowerRails>, support (exclusion) for pre-routed
nets.
* New: In Kite, In <GraphicKiteEngine> new menu entry for running the
router on pre-routed nets ("Detailed Pre-Route"), also integrated
in the all-on-one route command.
* New: In Kite, In KiteEngine, new method ::_initDataBase() that group
all the initialisation steps. It is a mix of calls between Knik and
Kite initializations which are intertwinneds (may have to devellop
a shared common base at a later point). It creates the Knik grid,
then the Katabatic grid, then load pre-routed wires and power rails
and protect isolated RoutingPads.
Add support for a map of pre-routed nets (to be excluded for
Knik calls).
The method "::run()" now uses function flags, firstly to know if
it is managing pre-routed wires or general purposes ones.
* New: In Kite, in <NegociateWindow>, the "::run()" methods has now two
modes. The normal one and the 'KtPreRoutedStage' that is for routing
pre-routed nets. When in pre-route stage, the wires are fixed at the
end of this step.
* New: In Kite, in <TrackElement> add decorator for AutoSegment
isUsedDefined().
* New: In Kite, in <TrackSegment>, the various ::canDogleg() methods
returns false for a pre-routed (user-defined segment).
* New: In Kite, in PyKiteEngine, added new method runNegociatePreRouted().
