Test commands for #23952 refactored to:
- avoid interaction with Tcl interpreter from thread functions (fixes sudden crash)
- get shapes outside of the thread functions (keeping only code being tested inside)
- run 100 threads instead of 2 (increases chance for data race to exhibit if present)
Linux compilation problems fixed.
Main changes are in "IntWalk_IWalking::TestDeflection(...)" function (IntWalk_IWalking_5.gxx).
Some test cases were corrected according to their new behavior.
AdvApp2Var_SysBase::mcrgene_ size reduced from 1000 to 32 elements, and each element reworked into typed structure.
fixed IntAna_Curve.cxx to prevent access to #NAN# SigneSqrtDis
fixed alignment of doubles by 8 bytes, and minor corrections
Minor correction: static const N given more specific name (MAX_ALLOC_NB)
Added QAcommands OCC23952sweep and OCC23952intersect
Added test cases bugs/modalg_5/bug23952_1 bug23952_2
