change name to TFormula::SetParameters(double*,int)  since it conflicts with TFormula::SetParameters(double,double)

the system will not find the associated pcm.

Based on #pragma cling load("libEvent") but compiler-compatible.
Fixes OrcJIT issue with availability of Event::Reset() which OrcJIUT needs to
have defined during object emission. Providing it as part of static init is thus
too late.

This also needed the implementation of rollback of nested transactions, so here
it comes.

Extremely handy for sources that require certain libraries to be loaded;
it's similar to MSVC's #pragma comment(lib"libToLink").

Add a backward compatible template constructor taking name of functor object and member function name (needed for CINT). Remove  instead the names from the new template constructor taking the function dimension.
