this is a requirement to allow the TInterface to get rid of move
semantics in the interface and allow PyROOT to work.

Use a EStatusBits 'enum' instead of a 'constexpr static int' (allowing automatic checking for overlaps)

Following the observation from philippe: Macro named starting with underscore are technically reserved for/by the compiler

- Add a couple of missing #include <algorithm>
- Replace _N by _NN (_N is already defined and used in some system math headers on Windows)
- Add #define __thread __declspec(thread)

- add dependencied on Core and IO (needed to resolve the symbols at link time on Windows)
- add a few symbols to be exported
- use the ANSI version of system functions
- convert the backslashs to forward slashs in the rootmap file path

- Use TMath::Pi() instead of M_PI (undefined on Windows)
- Replace 'uint' with 'unsigned int'
- Fix error C2057: expected constant expression with newX and newY arrays

 - Fix error C2057: expected constant expression in several array declarations
 - Outline (move from header to source) the IsCandleScaled() and IsViolinScaled() to export them from DLL
 - In fontembedps.cxx, replace unsupported memmem() function by std::search()
