0029940: The method TPrsStd_AISPresentation::SetSelectionMode() seems useless for transactions

A boolean parameter is added with a default value to the method TPrsStd_AISPresentation::SetSelectionMode().
By default, behavior of the method is not changed. But if the parameter's value is changed to FALSE, change of selection mode for the object will not influence the transaction. In other words, the attribute will not set modified and will not put into transaction delta. This behavior suits the usual notion of the object in an application: the object has color, material, transparency, but selection mode is not a property of the object. It is a property of an operation involving the object. Therefore, it has sense to remove the method SetSelectionMode() from TPrsStd_AISPresentation. For a while, it is marked as obsolete.

0029711: General Fuse operation produces invalid result

The following improvements have been introduced in Boolean Operations algorithm s:
1. UBTree is replaced with EBTree in Boolean operations to be able to add/remove elements into the tree of bounding boxes.
2. Repeated (nested) intersection of sub-shapes is performed with argument vertices whose tolerances increased during the operation.
3. The algorithms of Edge/Edge and Edge/Face intersection have been improved for the cases when the intersection point is located close to the edge boundaries .
4. New procedure has been implemented to ensure forced creation of Edge/Face common blocks in cases when the edge is really close to the face.
5. Post-processing of Face/Face intersection results has been improved.
6. Extension of the planar faces for Plane/Plane intersection is avoided.
7. Builder Face now better classifies potentially internal edges relatively to new faces with filtering by bounding boxes.

Side effect changes:
1. IntTools_ShrunkRange now keeps the length of the valid range of the edge.
2. The method BOPDS_DS::UpdateEdgeTolerance() has been removed as unused (replaced by the BOPAlgo_PaveFiller::UpdateEdgeTolerance()).

Thread Pool assigns a serial number for each thread allowing Multi-Threading algorithm to allocate thread-local storage variables as an array whose size is the same as the number of threads.

OSD_ThreadPool also redirects exceptions to a thread calling parallel execution and consistently initializes FPE exception handling.

New class Standard_Condition provides a platform-independent  tool similar to Event in WinAPI.

A new auxiliary function Standard_Atomic_CompareAndSwap() has been introduced
for performing atomic compare and swap of integer number.
Standard_Atomic_Increment/Standard_Atomic_Decrement fallback implementation

instead, it is expected that GCC should be properly configured targeting modern x86 architectures.

OSD_Signal now declares fFltExceptions as thread_local variable accessible through OSD::ToCatchFloatingSignals() property.
Standard_THREADLOCAL macro (wrapping thread_local attribute) has been moved to public header Standard_Macro.hxx.
