0026936: Drawbacks of inlining in new type system in OCCT 7.0 -- manual

Browse Source 
Restored possibility to have out-of-line implementation of DynamicCast() and STANDART_TYPE():
- Macro STANDARD_TYPE() now resolves to function get_type_descriptor() of the class
- Macro DEFINE_STANDARD_RTTI is replaced by two variants:
  - DEFINE_STANDARD_RTTI_INLINE works as before, defining DynamicCast() and get_type_descriptor() as inline functions
  - DEFINE_STANDARD_RTTIEXT declares DynamicCast() and get_type_descriptor() as exported
- Macro IMPLEMENT_STANDARD_RTTIEXT provides definition of DynamicCast() and get_type_descriptor() for a class

Upgrade script amended to replace DEFINE_STANDARD_RTTI by pair of DEFINE_STANDARD_RTTIEXT / IMPLEMENT_STANDARD_RTTIEXT if source file with the same name as header is found in the same folder, and by DEFINE_STANDARD_RTTI_INLINE if either source is not found or class is defined in the source (i.e. not in header)

Upgrade tool improved to recognize include statements with path prefix, like #include <occt/gp_Pnt.hxx>
Code corrected to eliminate warnings reported by upgrade tool.
Template of CXX file for testing upgrade tool added.

Documentation of upgrade procedure updated.
