Last week Martin Vala from ALICE came to me with a problem that he had
while using the asynchronous prefetching. There were basically two
main problems:

1. Trying to read a root file from an archive. Here the problem was
that when reading from an archive there is an offset of the file which
was not taken into consideration when the file was saved in the cache.
And this lead to a miss when reading the file from cache. I fixed it,
but I had to expose the value of fArchiveOffset from TFile.

2. The second problem was when reading using a TChain. There were some
synchronization issues concerned to the asynchronous thread that
actually does the reading. All this was happening because in the case
of TChain there is only one file cache which is re-utilized as we move
from one file to another. This was a pretty tricky issue.

I attached a patch made against the current trunk which fixes both
this problems. I gave the patch first to Martin to test it, and he was
satisfied with it. There is a small delay when the TChain moves from
one file to another because I have to wait for the async thread to
finish it's worked but over all Martin said that the performance is
way better than before. When I initially did the asyn pre-fetching I
had no idea about these two use cases, so that's why they popped up
now.

In TSeqCollection::Merge adding a TList of objects without a Merge method (e.g. TObjString)
to the output list did *not* work properly, in the sense that all but one set of objects is lost. 
This is because TSeqCollection::Merge (used by TList) is ignoring non mergeable objects instead 
of just adding them to the original list as we do at higher level in PROOF. 
This patch update the behavior of TSeqCollection::Merge to append the non-mergeable objects.

      - Small adjustments in getVal() to make it faster in most cases

        operations
   

    o RooBanner

      - Increment version tag to 3.48


    o RooRealIntegral

      - Add (dummy) method callgrind_zero() and callgrind_dump() as hook functions
        to facilitate improved callgrind profiling

        RooAbsReal::getVal()


    o RooAbsOptTestStatistic

      - Implement new fast-attach mechanisms for pdf and datasets: only readjust the
        buffer pointers of the dataset to the pdf observables, rather than reattaching
        the pdf to the dataset observables. This results in a _much_ faster 
        operation of setData() and no longer entangles the test statistics with observables
        of datasets that may be deleted during the lifetime of the test statistic

 
    o RooSimultaneous
