upmc: Updates for building C modules w/base UPM

Test commit for building C UPM modules.

    * Added C include directory
    * Added C utilities directory
    * Rename C++ upm.h -> upm.hpp to make room for C upm.h
    * Added upm_mixed_module_init function to src/CMakeLists.txt.  This
      function takes filesnames similar to upm_module_init and does a
      bit of processing before calling upm_module_init.
    * Added c example directory.  Changed c++ example names.
    * Added dfrph implemention for testing (C++ wraps C).  Added mraa
      to .pc requires for dfrph.  Tested against stand-alone project.
      Added dfrph c example.
    * Update implemention of pkg-config file generation.
    * Added two cmake cache variables: BUILDCPP and BUILDFTI
    * Removed src from swig_add_module calls, added libname to
      swig_link_libraries calls.  Shrinks swig'ed binaries by ~13%.
    * Added install target in upm/CMakeLists.txt to install C header,
      directory.  Is this where we want this?
    * C FTI header directory is include/fti
