o RooAbsArg

    - Defer reading of RooRefArray::_proxyList to phase 2 of workspace I/O
      to avoid potential read-order dependencies

  o RooBinnedGenContext

    - Eliminate phase-2 correction for Asimov datasets as these may
      duplicate correction factors
Improved ROOTConfig.cmake to support COMPONENTS and TOOLS. Fixes ROOT-5371 and ROOT-5787.
Additional documentation to commit a689d03
Fix: http://root.cern.ch/phpBB3/viewtopic.php?f=3&t=17382
The TMathText case should be taken into account in GetBoundingBox, GetXsize and GetYsize.
Do not ignore Mode and ForceUpdate in AliEn dsets
Hidden interface by making a method protected
Faster AliEn dir verification code
Improved AliEn dataset retrieval with run ranges

Since run ranges usually contain many "holes", yet they are more
convenient to use than specifying a list of runs manually, a
preventive check to prune invalid run numbers is performed: AliEn
queries on non-existing runs are consequently avoided.
Added option pythia6_nolink (CMake) to postpone linking with pythia6 library. Fixes ROOT-5802
For label axis, when setting a new label the THashList (fLabels) need to be rehashed
(fix ROOT-5025)
Prevent propagation of user flags to bundled autotools projects

autotools allows to set site-wide flags to configure by reading from the
file pointed to by the environment variable CONFIG_SITE, see e.g.

  https://www.gnu.org/software/automake/manual/html_node/config_002esite.html

Since we try to set consistent compiler and linker flags in bundled
autotool projects ourself, letting flags from CONFIG_SITE leak can lead
to an inconsistent build (e.g. `./configure` on a 64-bit platform and
CONFIG_SITE with CXXFLAGS=-m32).

Since the configure of bundled projects is run in the build and not the
configure phase unset CONFIG_SITE prevents propagation of any user
flags.

update for iOS 7 support.
Fix for a root view controller not set (was fixed for iOS 6 many years ago??? where is it??)
Implement TProfile::SetBinLength  to update the profile structure when the number of bins has changed.
This fixes the problem callingTProfile::Rebuild (fix ROOT-5611)
