This `std::vector` is allocated in `tmva/tmva/src/DataSetFactory.cxx`
(line 162) and then passed to `TMVA::Event::Event()`. Then it's up to
`TMVA::Event` to take care of releasing this memory.

This solves a small memory leak.

Added 'builtin_fftw3' option to build the FFTW static library that is used to build ROOT. The default is OFF.

Reduce the memory taken for re-creating Tormula objects with the same expressions by using a local static map to cache the function pointers.

The patch adds missing OpenSSL include directories. Otherwise the
ones from standard system location is being used, which might not
be installed. E.g., CMSSW provides their own build of OpenSSL and
build machines do not have OpenSSL libs and dev packages installed.

`OPENGL_FOUND` and `OPENGL_GLU_FOUND` are only available if
`find_package(OpenGL)` is used, which is not the case if you are
building without Cocoa on OSX.

Check for `OPENGL_LIBRARIES` which is set in both if-statement paths.

Changed the XROOTD version to 4.2.1 when using 'builtin_xrootd' option. A number of warnings had to be silenced.

This reverts commit 125a93e0.
It fails in the following case (roottest/root/io/evolution/pragma_read):
dictionary for a/b.h which includes a/c.h as #include "c.h"
This will add a fwd decl with annotation "c.h", but this header cannot
be found. Instead we'd need "a/c.h"...

Allow to bind http port with loopback address.
This restrict access to http server only from localhost.
One could either specify 'loopback' option in constructor:
  new THttpServer("http:8080?loopback")
or in clear text specify IP address to which http socket should be bind:
  new THttpServer("http:127.0.0.1?loopback")
If host has several network interfaces, one could select one from them

After reverting Tim patch in removing name in RooLinkedList  we can set again the name in the detailed output list of RooAbsStudy

Fix copy ctor of RooAbsAnaConvPdf. This problem was noticed by applying the previous patch of T. Adye in the RoolinkedList::Add to checking pointers added to the list.
Restore the _name data member of RooLinkedList. This fixes the detailed output functionality of PROOF

 Restores the speed of RooLinkedList lookups (and some other operations) to that from
  ROOT 5.34.17 and before. The hash table was used previously, but this was disabled in
  ROOT 5.34.18+ because it gave incorrect results when list entries were renamed.
  This patch allows the hash table to be used without risk of failure, improving the
  speed of operations that make heavy use of RooFit lists, such as combining and
  importing (eg. factor 3 on an import).

  Details from Tim Adye:

  An update (26/06/2014) included in ROOT 5.34.18 fixed name lookups with RooLinkedList::findArg()
  when a list element had been renamed, by disabling the hash table optimisation.
  There was still an issue with find(name) and when removing or replacing renamed elements.
  This patch should mostly restore (or even slightly improve on) the speed we had before that update
  (eg. in 5.34.17), but with corrected find, remove, and replace operations.

  For all this to work, I had to make a few changes to how the name registry is used.
  RooLinkedList now has _useNptr enabled by default, but only uses the name registry when it
  is safe and efficient to do so. If a RooAbsArg is ever renamed, a flag is set in the name registry
  (actually a bit in the new TNamed) to indicate that a hash table lookup may give a false negative
  for that name. That will permanently (for this job) prevent a quick lookup for that name,
  but that's OK since renaming is relatively rare.

  To speed up the name registry (which is now used more often), I increased its static hash table size
  from 31 to 100000. That might seem like a drastic change, but since this is a singleton it only
  adds 781 kilobytes to the total memory usage.

  This patch also includes a few minor fixes to RooHashTable: fix when a replaced element had a
  different name (slot), fix for find(TObject*) which always failed (but wasn't used),
  and a small optimisation for RooHashTable::findLinkTo().

  Several improvements to reduce the RooFit memory use, especially for the combined
  CMS Higgs coupling workspaces (eg. reduce the full CMS workspace requirements
  from 7.3 to 1.8 GB, with a more modest 5.3 to 4.6 GB improvement for an ATLAS workspace).

  Details from Wouter Verkerke:

  - For any RooSimultaneous component in which there is a pdf tagged with attribute
    "MAIN_MEASUREMENT", only that pdf is forwarded to the component calculator,
    thereby stripping of all subsidiary measurements (these are evaluated elsewhere anyway)
    This is already done automatically for ATLAS binned likelihood, where the BinnedLikelihood
    attribute has a similar effect.
    Since CMS attaches 2305 subsidiary measurements to each of their O(250) channels.
    this procedure avoids the replication of ~500,000 RooGaussians and 1.5 million associated RooRealVars.
 - The default buffer size allocation for TTree attached RooVectorDataStores is reduced from 4096 bytes per branch to 1024.
 - The initially reserved vector size of Roo(Obj)CacheManager for internally cached objects is reduced from 10 to 2.
 - The TNamed data member of RooLinkedList is removed (was only used in one very obscure place).
 - The chunk size for memory pools for RooLinkedListElems is reduced from 1M to 256K.

  To take advantage of this for the CMS workspace, the pdf terms should be tagged with the "MAIN_MEASUREMENT"
  attribute. If not already included, it can be added with the following code snippet.

  RooFIter iter = w->components().fwdIterator() ;
  RooAbsArg* arg ;
  while(arg=iter.next()) {
    if (arg->IsA()==RooAddPdf::Class() && TString(arg->GetName()).BeginsWith("pdf_")) {
      arg->setAttribute("MAIN_MEASUREMENT") ;
      cout << "component " << arg->GetName() << " is a cms main measurement" << endl ;
    }
  }

from Wouter: change components to return a RooArgList instead of a RooArgSet to not remove duplicates (e.g. RooProduct of x*x )

- Add Hash method to RooLinkedList otherwise it cannot be used correctly in THashList classes (e.g. when using it with PROOF)
- Fix seeding of random numbers when using it with PROOF (use the worker number in the seeding) to be sure different seeds ar generated for each worker

   - Introduce first moment as offset in calculation of second moment
     to promote numeric stability of calculation when first moment is large

 o RooCmdConfig

   - Increase length of string arguments allowed

 o RooCustomizer

   - When replace operations are executed with missing source or target expressions,
     ignore the offending operation with a warning message, rather than canceling the
     entire transaction

Speed up RooWorkspace::import by using a has table for the internal Workspace collection if size is > 1000 and by speeding up the removal of the set which is cloned in the import. We don’t delete the set which calls safeDeleteList. It is not needed, the set contains a list of all the nodes, so we simply delete just one by one.
