Merge remote-tracking branch 'origin/knepley/fix-plex-hdf5-label' into tisaac/dmforest

* origin/knepley/fix-plex-hdf5-label: (50 commits)
Plex: Fixed HDF5 output for DMLabel - The ISAllGather() was being called with an IS that had COMM_SELF - Also, we needed to protect for empty index arrays
superlu_dist: install target should first make sure prefix/[include,lib] dirs exist - similar to superlu
dm: add DMRemoveLabel() fortran interface
nightlybuilds: allocate more time to run arch-linux-xsdk-dbg build...
Remove superfluous information messages
Cannot have rank 1 print before parallel print since it may end up before or after the print from process 0. There change to have rank 0 print the sequential matrix
Bib: Added ref
Plex: Update ex12_5 with correct level-2 overlap
DMLabel: Add missing cleanup for DMLabelGather()
mpiuni: check for "long_long" before checking for "__int64" [as "typedef __int64" gives error with icc] Note: cannot use 'int64_t' as 'typedef unsigned int64_t foo' gives eror with icc
Add filter for solaris linker scope warning to master since that is used in nightly tests of next
Previous commit did not correctly handle downloading from --with-packages-dir
Use special error code of 10 for output list of needed downloaded package tarballs otherwise the outer configure.py script converts the error code to an error message we do not want.
Have ./configure return a nonzero exit code when --with-packages-dir detects missing packages so that calling scripts know this is occurred simplify some code
Completed support for --with-packages-dir=directory that allows --download-xxx features to be cleanly used behind firewalls etc also updated to docs to indicate this new feature
Adding supporting for --download-xxx to reported needed downloads when off line or behind a firewall and using local copies when available with the --with-packages-dir=directory option
Fix typos in linesearch impls:armijo, morethuente, owarmijo.
