NCollection containers update:
- NCollection_Array1 - updated functionality
- NCollection_Array2 - NCollection_Array1 as a wrapper for 2array
- NCollection_Vector -> NCollection_DynamicArray was renamed and reworked.
TCollection:
- Use static empty string to avoid allocations on empty string
NCollection allocators update:
- NCollection_Allocator - allocator that used Standard::Allocate
- NCollection_OccAllocator - allocator-wrapper that used OCC BaseAllocator objects
- NCollection_IncAllocator - rework to increase performance
Standard:
- Rework functionality to use different allocation libs
- Implement basic of new way to wrap allocations tools
- Define 4 ways to allocation (defines in configure stage)
Additional changes:
- Hash function uses std::hash functionality
- size_t as a hash value
- New HashUtils with Murmur and FVN hash algo for x32 and x64
- Deprecated _0.cxx and .gxx DE classes reorganized
- Create own utility for std memory
- Update Standard_Transient to be more platform-independent
Math TK changes:
- math_Vector -> match_BaseVector<>
- Buffer decreased to cash 32 elements instead of 512
