Parser::Scope versus Sema::DeclContext are now checked for cross-vailidity.
Emit the TU-transaction explicitly instead of relying on a first transaction.
The typename extraction now takes a stream instead of a string to write to.
The llvm::Linker has much reduced functionality; use llvm::sys::Path instead to find dynamic libraries.

the callbacks must be triggered for those, too.
As they are not part of a transaction (think "module") they are now sent to the deserialization listener.
This can be removed once the modules work.
Set the state of the transaction to Committing before the static init - which might trigger more decls even though CodeGen has been run over the decls.
Forward DeclCollector::HandleInterestingDecl() to DeclCollector::HandleTopLevelDecl() for decls from the AST reader / from headers describing libraries.
Empty transactions must be passed to TCling; they trigger the sending of deserialized decls to ROOT/Meta.
Don't start TCling's artificial TU Transaction if the transaction coming in is empty - we need a decl to get the ASTContext.
Swap the deserialized decls before handling them in TCling, such that nested calls don't see the same decls again.

Add comparison ops: I needed them for a dead end and now I have them and the compiler won't generate its own.

Rephrase !(a==b).
This file still needs major refactoring to remove code duplication.

collecting->completed->committing->committed
Make m_DeclQueue lazily allocated to reduce sizeof(Transaction) in an effort to make the TransactionRAII cheaper - second part is coming up.
Remove unused thus unneeded and annoying (non-const) iterator interfaces; they clash with the constness of the EmptyQueue.

The issue is that sometimes we don't have a begun transaction. This can happen
mostly in cases when the code doesn't come from text representation but:
* From lookup, where template is being instantiated
* From a PCH/PCM, where a decl was deserialized.
This patch solves the first case: When we do findScope we have to instantiate
the declaration if needed.
Every time there is a chance that generated code's declarations can be orphaned,
we have to explicitly push a transaction so that we can keep the integrity.

Some functions return temporary objects. Eg:
std::string getName() {
return "ROOT";
}
In that case the lifetime of the temporary variable is defined by the caller.
Such function called by TClingCallFunc would cause undefined behaviour, because
there is no actual caller and the compiler cannot define any lifetime.
In order to provide such concept we have implemented cling::StoredValueRef, which
is a reference counted cling::Value. As long as somebody "has" a copy of it, the
boxed value (and the occupied memory) will live.
However cling::Value and cling::StoredValueRef expose LLVM/clang/cling internals
to ROOT. We want to avoid for now exposing LLVM/clang/cling internals, so we have
TInterpreterValue, which makes cling::StoredValueRef opaque.
*New interface taking TInterpreterValue is added to the TInterpreter to allow the
users to manage the lifetime of the returned temporaries.
*Replace the occurrances of cling::Value with cling::StoredValueRef to avoid
any lifetime management issues.
*Minor optimizations of the existing implementation
*Tweaks to the build system so that TInterpreterValue.cxx could
#include cling/Interpreter/StoredValueRef.h
PLEASE NOTE: This is not the final implementation it needs polishing. Eg. there
is a bug that should be fixed soon, which doesn't allow to get the actual result
out of the TInterpreterValue.

Remaining:
* callfunc issues finding functions
* vtable issues (likely related)
* in stressHistogram: Test 3: Projection with Range for Histograms and Profiles................OK

Reshuffle gCling; definition is now provided by the Interpreter internally, not in any header.
This will cause missing symbols in libraries instead of silently creating dumplicated (JIT / library).
Still requires Vassil to add a parameter to LifetimeHandler() - but this will cause a cling test failure as a reminder.

That won't work for construction; so replace with placement new.
Also need default c'tor for Value() to initialize m_GV correctly.

This header gets included by enabling dynamic lookup, and by RegisterModule() of G__Meta.
We need the latter for the many-pcm case.
