In Inspect use TDataMember to get transient info.

To support the case where the information is past via
a xml selection file rather than looking at the comment
string, use TDataMember::IsPersistent.

Fix a typo.
Remove a couple of unused variables (thanks Olivier for the feedback)
Fix ROOT-5938: transform filenames into valid C++ variable names

o Small fix to documentation removing reference to genreflex.py
Remove code and leverage the ROOT::TMetaUtils::GetCppName function
fix warnings found by clang 3.5 and c++11 (fixes ROOT-5899).

Still auto_ptr deprecation has to be tackled.
Remove unused argument for CallShowMembers
Avoid spurrious errors message in BuildRealData

Do not attempt to create the real data for a class
where it might fail and where we do not really need
it (i.e. transient case when handling a data member
which is a collection and attempting to create the
real data for the class representing its content)
Start deprecation of ShowMember member function.

Bypass function call when we are sure of the
implementation (because we generated it!).
fprintf->Warning
In SavePrimitive(): make sure the vector names are all different (useful when saving multigraphs).
Enable CanSplit check with just a fClassInfo

ShowMember functions are going to be deprecated soon, so we must
also be able to check the value of CanSplit when we just have
the intepreter info.
No longer write external ShowMember function
New version of SavePrimitive()
Fix for FTGL library in CMake build (ROOT-5945)
fixed JIRA issue 5942 (division by zero)
removed dublicated code (coverity CID 54064)
New version of SavePrimitive()
Enable relocatable binaries (ROOT-5939).

Even if CLING_INCLUDE_PATHS is set, cling might end up elsewhere.
So always look for the include/ that's next to bin/cling.
Remove dict support for free standing ShowMember

Remove all traces/interface that were used to register free
standing ShowMember functions from the dictionary (and from
the TClass initialization).

The member function ShowMembers now most vestigial and is
solely an entry/top level interface and is not used
internally.
