ENH: Remove jobserver thing, which was fixed in the build_tcltk.sh.in and remove a whole bunch of tests from memory checking

A new CVS repository was created on 2004-03-12 to fork ParaView during
transition to a new source tree layout.  The new repository was
created using a combination of directory-level server-side symlinks
into the old repository and copies of ,v files to preserve per-file
history.  This commit was manufactured during conversion from CVS to
represent the fork as a branch.

The new source tree layout added Utilities/IceT which was not
previously distributed as part of the source.  We represent this
addition by adding the IceT submodule.
