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()

an array of type T* is stored in the returned column as
vector<T>: the ownership has to be transferred to the
"extracted column".

To implement this feature, these changes were applied:
- The Take action has been restructured in order to detect the
presence of the array_view<T> type as column type. The changes
are mainly confined to transformation of types at compile times.
- The TakeHelper template and its specialisations have been modified.
Now we not only take into account the case of returned collection
equal to to vector for optimisation, but also the case where the
column in the dataset is a C style array. The specialisations of the
TakeHelper template are now 4.
In addition, a bug was fixed: the Exec function was accepting the
value of the column for a certain entry as a value, therewith potentially
triggering expensive copies.
- Some static utilities have been added in the ROOT::Internal::TDF
namespace to factor out verbose operations linked to the points mentioned
above.

 - enclose min() and max() in parentheses to prevent the following compilation errors (min and max are defined as macros in Visual Studio):
     error C2589: '(' : illegal token on right side of '::'
     error C2059: syntax error : '::'
 - implement the basic_string_view operator == (for const char *) (was somehow not resolved by Visual Studio). Thanks Axel for fixing it

Use WIN32 instead of MSVC in cmake and avoid duplication of url and md5 for LZ4 (thanks Guilherme for the feedback)
