Do not pass "/usr" or "/usr/local" as path to configure

Add packages c-blosc and hdf5-blosc

Add variant for boost graph and parallel graph

Make Boost an optional feature of Trilinos.

Package serf also depends on zlib.

Add patch to compile pcre with Intel 16.0.3 compiler

Use https for github in Caliper package

c-blosc provides the Blosc compression filter, and hdf5-blosc provides a plugin for HDF5 to use that filter.

I have been unable to build Boost with some toolset/platform combinations. The
users I support don't need the Boost features in Trilinos, so I have been
manually hacking trilinos/package.py to disable boost. I would like to propose
that these changes be added to the released version.

+ Add boost as a variant, default to true so there is no change to existing
  behavior.
+ Move the CMake configure options related to Boost into a conditional block
  that is triggered by "if '+boost' in spec".
