The previous mechanism of determining TObject::IsOnHeap() was found to be inaccurate and thread unsafe. The new way is to fill the memory area returned by calls to TObject::new with a special value and as the first operation in TObject's constructor look to see if the uninitialized member data have that value set. If they do we assume the object was made via a call to 'new' and therefore is on the heap. The interface in TStorage used to implement the old mechanism has been declared obsolete via the use of ::Obsolete.
This is the only use of TStorage::IsOnHeap outside of TObject constructor. It appears to be checking to see if the object might not be available anymore and if so don't talk to it. This test is highly inadequate to answer that question and since we want to get rid of TStorage::IsOnHeap for other reasons, it was decided to remove its use here.
In order to avoid thread-safety issues, the static class member TClass::fgCallingNew is no longer a class member and is instead a file scoped static declared thread_local. It was necessary to not have it is a class member since CINT could not parse the new thread_local keyword.
Helgrind was complaining about a global being written without a lock. In this case, the global is not actually changed so we do a check to see if the old value was the same as the value we set and if so, we don't bother to change it.

Write special values into memory after TObject::new called in order to have TObject's constructor determine if the object was made on the heap.
Removed obsolete static member data and obsolete function bodies. Added ::Obsolete calls where appropriate.
Instead of having TObject's constructors know explicitly about how TStorage::ObjectAlloc works, we no encapsulate that knowledge into TStorage::FilledByObjectAlloc. Additionally, switched from fBits to fUniqueID when checking for assignment from 'new' in order to more easily create a valgrind suppression entry.
To determine if TObject is on the heap we read the value of a member data before it has been set by the constructor. If it was heap allocated the TObject::operator new will have filled special values into the memory area. However, for stack allocated it is unset. This makes valgrind report an error. Given we intend this behavior, we suppress the message.
Since TKeys can be made by different threads, it is necessary to protect the global used to assign the GUID of TKeys, keyAbsNumber so that we are guaranteed to get a unique value for each request. C++11 atomics give that guarantee.
The caching of TClasses by Cintext could be updated at anytime and therefore needs to be protected when running multi-threaded.
The zip functions use globals to hold state while calling from function to function. Such use is not thread safe. Given the globals are only used during a function call chain, it is safe to change them to thread local. Given this is compiled by a C compiler, we must use the gcc specific __thread keyword.
When new files are opened or closed, gROOT->GetListOfFiles() is updated. If the opening/closing happens on different threads then we need to serialize all access to that list. This changes uses gROOTMutex to serialize those accesses.
The list of TStreamerInfos held by a TClass can change while processing and therefore access to it must be protected when using multiple threads. The gCINTMutex is used for this purpose since the TClass is considered part of the CINT data model.
We now protect all threaded access to TClass::GetStreamerInfos. In addition this change properly handles updating the TStreamerInfo cache in a thread safe manner.
When running with multiple threads, we need to avoid unnecessary changes to TStreamerInfos. Therefore we check to see if the TStreamerInfo is optimized before setting it as unoptimized and rebuild it.
The following threading issues were corrected - TROOT::GetListOfClasses was protected via gCINTMutex - Access to TStreamerInfo lists were protected via gCINTMutex - Setting of the cache for current TStreamerInfo and for the list of conversion TStreamerInfos is protected via std::atomic<>
Several changes were needed to make this thread-safe for the I/O case 1) Protect the list of handlers with its own Mutex 2) Use a thread_local variable to hold the status of reading a directory 3) Use gCINTMutex to protect access to fBasesLoaded. Had to use gCINTMutex since we need threads trying to read the same dirs to wait for the first reader to finish so the lock has to be held over the whole call. In addition, gCINTMutex is sometimes taken before and sometimes during the call so using a different mutex would lead to a deadlock situation. NOTE: fReadingDirs is not used anymore but is still in the code to allow binary compatibility to easy testing. This should be removed in the future.
The order of locks between gGlobalMutex and gCINTMutex is undefined and TStorage::ObjectDealloc calls were involved in order reversal problems. As it turned out, there is no data structure that needs protecting in TStorage::ObjectDealloc so we do not need the lock.
TUUID used statics that were causing race conditions. The fix was to change the statics to thread_local.
-There was a potential deadlock situation between gErrorMutex and gCINTMutex. The fix was to limit the scope of gErrorMutex locks -Changed buffers from static to static thread_local. This allowed gErrorMutex to be more limited in scope.
This fixed a problem found by helgrind.

Before, MetaParser might have pointed to a StringRef whose storage
was gone, see asan failure in roottest/cling/other/runfileClose.C below.
This was caused by recursive uses of MetaParser; see stack trace below:
the inner recursion returned, but as the same MetaParser object was used
by both frames, the objects cursor now pointed to freed memory.
Instead, create a MetaParser (and MetaLexer) object per input. That way,
their lifetime corresponds to the lifetime of their input.

The test was dynamically allocating the array data members of the `Data` struct, but never deallocating them. This commit polishes the `Data` struct definition and ensures proper management of the data members. The previous way of writing data to the TTree was leading to a bad memory access in the ReadBasicPointer inlined function in TStreamerInfoReadBuffer.cxx while reading the `double*` array. In particular, the issue arises when accessing and then deallocating the array at the current index provided by the `TCompInfo` object. ``` Target 0: (repro.out) stopped.

The test was dynamically allocating the array data members of the `Data` struct, but never deallocating them. This commit polishes the `Data` struct definition and ensures proper management of the data members. The previous way of writing data to the TTree was leading to a bad memory access in the ReadBasicPointer inlined function in TStreamerInfoReadBuffer.cxx while reading the `double*` array. In particular, the issue arises when accessing and then deallocating the array at the current index provided by the `TCompInfo` object. ``` Target 0: (repro.out) stopped.
