Memory leak in bupdater for PBS and LSF

Version 1.16.3 of BLAH is affected by a quite critical memory leak in the bupdater component for LSF and PBS. Because of that the usage of memory of the bupdater process will keep increasing till when it crashes/it is killed by OOM. It is then automatically restarted by blah.

SGE is not affected by this problem

For LSF and PBS, the workaround is to configure the blparser using the old method (see: http://wiki.italiangrid.it/twiki/bin/view/CREAM/SystemAdministratorGuideForEMI1#1_2_4_Choose_the_BLAH_BLparser_d) or to the restart from time to time the bupdater.

Relevant bug: https://savannah.cern.ch/bugs/index.php?89859

Problems starting the bupdater and bnotifier with (S)GE

With SGE, there is a problem when starting the bupdater and bnotifier: 

Starting BNotifier: /usr/bin/BNotifier: sge_helperpath not defined. Exiting
[FAILED]
Starting BUpdaterSGE: /usr/bin/BUpdaterSGE: sge_helperpath not defined. Exiting
[FAILED]

The workaround is to uncomment the variable: 

 sge_helperpath=/usr/bin/sge_helper

in the blah.config file.

No dynamic info published for one VOview

For one VOView the lcg-info-dynamic-scheduler doesn't publish information, and therefore the values defined in the static ldif file is used.
