For setups having limitations with open ports, such as in some cases PoD, xproofd provides the
possibility to serve the files produced during running via the same port. This was implemented
by starting a rootd process upon an incoming request for a file. The use of xrootd for this
purpose was not possible with earlier versions of XRootD (up to 3) because the file serving
protocol was not available as separate plug-in.
This patch enables the use of xrootd for this purpose and deprecates the use of rootd .

Plug-in versions have been introduced in XRootD version 3.3.0 .
Should fix issue in EC builds, where XRootD 3.2.7 is still picked-up from AFS. Should update this.

This patch - together with  cc884ecb832f025af4dd5eea0eb27ad017e76b0d - adds support fro XRootD version 4.
The bulk of the patch copes with the changes in the XRootD network classes to support IPv6. The rest is mostly
handling of the changes in packaging.
The PROOF part still uses the old XrdClient (still delivered with XRootD).

Conflicts:

	proof/proofd/src/XrdProofdNetMgr.cxx

The changes are all related to the use of gendered or binary language in
the comments, messages, and documents (e.g. referring to the user explicitly
as "he" or "he/she").  I searched for thse instances and changed them to
the gender-neutral singular they (http://en.wikipedia.org/wiki/Singular_they).
In the process I fixed quite a few typos that would show up in the
auto-generated documentation.

By Jean-François Caron jfcaron@phas.ubc.ca).

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).

   Fixes in xproofd:
   - Make sure that unused XrdProofdResponse objects are properly invalidated instead of deleted;
     this avoids improper usage of invalid instances and subsequent crashes.
   - Fix problem with two variables being initialized only once in recurrant loops; this prevented
     proper Reset of XrdProofdProofServ instances and proper active session accounting (and session
     cleanup).

  Patch implementing an interface to start proofserv processes with an external launcher
  and an implementation using 'system' instead of 'fork', as done in PROOF-Lite. The goal
  is to consolidate the startup process, avoiding the problems related to forking in a
  multi-thread process.
  For the moment the new startup is disabled by default and can be enabled via a new
  switch 'userfork' in the 'proofservmgr' directive:

                  xpd.proofservmgr usefork:0

  Add the possibility to access the files on the workers via the same port used
  by PROOF. This is useful for cases when it is not possible to start a file server
  daemon on a different port (because, for eample, of a firewall or just inconvenience)
  and workers do not share a file system.
  Internally this works by forking a 'rootd' after identifying a file request and
  trasferring the connection to it. The client side is a TNetFile and it is triggered
  by the protocol "rootd://" (the just implemented etc/plugins/TFile/P120_TNetFile.C
  includes this protocol).
  On the server-side this new service is disabled by default and requires the directive
  
       xpd.rootd allow

  to be active. By default the 'rootd' is started in 'read-only' mode and no authentication.
  This can be change with some switches supported by the directive; for example
 
       xpd.rootd allow auth:full mode:rw

  starts 'rootd' in 'read-write' mode and authentication controlled by etc/system.rootdaemonrc .
  The list of avaialbe switches is documented at

       http://root.cern.ch/drupal/content/configuration-reference-guide#rootd

  The directive 'xpd.rootdallow' can be used to define the list of hosts allowed to use
  this service: see

       http://root.cern.ch/drupal/content/configuration-reference-guide#rootdallow

  The default setting of the environment variable LOCALDATASERVER has been changed to be
  "rootd://<host>:<proof_port> if file-serving via 'rootd' is enabled. In this way 
  TProofOutputFile automatically sets the correct default URL for further access from the
  master or other workers.
  The can always be overwritten with a dedicated 'xpd.putenv LOCALDATASERVER=<my_setting>'
  directive .

   Save the status of a 'proofserv' session into a new file in the 'activesessions' area.
   The full path of the new file is

          <admin_path>/.xproofd.<port>/activesessions/<user>.<group>.<pid>.status

   The status indicates whether the session is idle, running or queued.
   The status is updated every 'checkfq' secs (see xpd.proofservmgr; default 30 s).
   The status is dumped by the reader thread of TXProofServ and therefore its r/w access
   is protected.

   This change is needed for PoD optimizations.

   Build also a binary named 'xproofd' which runs a xrootd daemon with only the XrdProofdProtocol

  Patch adding support for session queuing in the scheduler (from Jan and me).
  This allows to control the number of sessions allowed to process queries concurrently.
  The feature is enabled by a new parameter 'queue:fifo' in the 'xpd.schedparam'
  directive.

  In case of static worker assigment (default, random, round-robin) the max number of
  running sessions can be limited by another new parameter 'mxrun'; for example
  'xpd.schedparam default mxrun:3 queue:fifo' will run concurrently only 3 sessions.
  Additional requests are queued and run as soon as one of the running sessions goes idle.
  The current policy is FIFO, so that there is a rotation among queued sessions.

  In the case of load-based worker assignement, the max number of running queries is
  determined dynamically.

  This option requires dynamic, per-job scheduling.
