* Change: In Hurricane::SharedPath, the hash for the shared pathes, which serves for Map<> storing, were computed "on the fly" at each ::getHash() call, and were involving recursive calls of all the hashes along the components of the shared path. This is terribly slow especially in a design with a deep hierarchy (typical case LS180). Now, at the cost of one supplemenental unsigned long in each SharedPath, it is only computed once in the constructor, and is no longer recursive (only access the *first* tail, if any). As a consequence, the re-display computation delay becomes bearable. But also speed up any transhierarchical walkthough.

* Change: In Etesianengine::toHurricane(), no longer call interTies(). This *should* no longer be needed as almost all standard cells (SxLib & FlexLib) already contains polarisation contacts. So do not need to disturb the placement. Secondly, in presence of a H-Tree, when there is not enough space to insert a sufficient number of tie cell, the lefmost one in the sub-row is shifted to left, overlaping the H-Tree buffer cells. This is a bug (even signaled by a warning). But as this part is disabled, I won't correct it soon...

* Change: In Cumulus/plugins.block.Block, for standalone block, the external Pin where created non-square, the "perpandicular" side made a half wire width. But in case the wire width was an odd number of physical grid, it was leading to offgrid screaming in the GDS driver. Now, just make them square...

* Bug: In CRL::GdsDriver::GdsStream::operator<<(Cell*), when looking for layer names ending with ".pin", must also check that the string is at least 4 characters long.

The CMake version set was so old that obsolete policies were being enabled and breaking FindPython. 2.8 should still be old enough not to cause problems for any current users. Signed-off-by:

* Bug: In KatanaEngine::annotateGlobalGraph(), the minimum track reservation was not applied correctly. Instead of adding the *difference* between the minimum and the current reservation, the minimum was simply added. Leading to too high reservation. And loss of control about what we were doing on the edges capacities... Really stupid.

large enough instead of creating one big via along the horizontal cell power lines, we create one big VIA at each end. To avoid to create too massive obstructions. But the thresold was too high for cmos45, leading to short with the clock tree trunk.

* Change: In bootstrap/coriolisEnv.py, when all tries to locate the installation root in predefined locations, try the directory the script is installed in. This allows for a user to use an installation made in another user's account.

* Bug: In Anabatic::_desaturate(), the set of invalidated GCells was never cleared between iterations of desaturated GCells. This was not a memory leak per se because, in the end, the set was freed. But it did induce a gigantic bloating in memory. This finally explain the strange slow down in that stage. Detected in ls180+cmos45. * Change: In Anabatic::GCell, add a flag for each depth to avoid desaturating twice the same GCell (maybe not needed now that the bug is corrected, but it ensure a no-looping).

* Bug: In cumulus/plugins.block.configuration.GaugeConf.expandMinArea(), The minimal length of the segment intermediate wires where computed for the minimal area using an integer division ( // ), which is stupid for less than 1.0 values. They are real quantities at this point... This was making the DRC of ls180 failing.

Note: We don't suppress warnings due to unused variables or functions, as we may need them later or in debug mode... * Change: In Hurricane::DBo::~DBo, add a noexcept(false) because constructed by default destructor of derived classes seems to loosen it. The right solution whould be to explicitely define all virtual destructors (too lazy for now). * Change: In Viewer::Script, replace the deprecated PyModule_GetFilename() by PyModule_GetFilenameObject(), Unicode support again...

* Change: In bootstrap/coriolisEnv.py, the script was looking to pythonX.Y (like "python2.7" or "python3.6") only. Now added "major" only directories like "python2" or "python3".
