Fix for building with xrootd. The FindXROOTD.cmake has been simplied and a single variable XRROTD_INCLUDE_DIRS returns the normal and private include dirs. The clients packages in ROOT proof, netx and proofx have been adapted.

When creating mergers, the code iterates over all slaves to figure out how
many workers should be assigned to each merger. This is usually fine,
unless not all are active. In that situation it creates mergers that wait
forever (or almost forever) for workers which will never connect, which
obviously screws up the job. The fix changes the merger creation to iterate
over fActiveSlaves instead of fSlaves.

[From B.Butler, M.Swiatlowski]

Provide git commit and branch info to the system. The methods:
   TROOT::GetSvnRevision()
   TROOT::GetSvnBranch()
   TROOT::GetSvnDate()
have been replaced by:
   TROOT::GetGitCommit()
   TROOT::GetGitBranch()
   TROOT::GetGitDate()
Also the RVersion.h has changed and:
   ROOT_SVN_REVISION
   ROOT_SVN_BRANCH
has been replaced by:
   ROOT_GIT_COMMIT
   ROOT_GIT_BRANCH

This patch is meant to fix an issue causing the PROOF progress bar to get
to 100%, then scroll at 100% for about the same amount of time again before
finishing. The problem was finally tracked down to a failure to update a
TProofProgressStatus object's fLastUpdate field on a worker before it is
sent to the client. The last update time was always the initial time,
causing the reported rate (and progress) to be about a factor of 2 too
large. The patch also includes a minor fix for the scrolling in general,
which is irritating (it can still happen with the bugfix a bit at the end
of the job if the estimate overshoots the total number of entries).

   - Set client flag so that VerifyDataSet can be submitted as parallel
   - SAve arguments to EnablePackage so that they can be used when replaying the issued commands
   - In stressProof: when in 'dyn' mode, skip some new tests which do not apply.

Replace all occurrences of strlen(x) == 0 with !x[0] which is far cheaper for long strings.

This patch adds support for XrootD 3.3.1 (out today) and higher. It
disables xrootd if the version is 3.3.0 (missing headers).

  Make sure that a selector passed by object is never destroyed.
  Fixes an issue when a automatic allocated selector is passed by reference
  reported on root-dev.

Unfortunately I forgot that there are AliEns around with old xrootd v3.0.4
which is intermediate and was not detected correctly after the patch.
Now I have checked with all possible variants: 3.0.4, 3.1.0, 3.2.x and trunk.
