Sandia OpenSHMEM v1.3.2 RC1

• Enabled single-process, direct execution of SOS binaries with simple PMI
• Enabled VPATH builds
• Added argument error checking for all SHMEM routines, enabled at compile time
  via --enable-error-checking.
• Added new C and Fortrans bindings generator that generates all headers and
  bindings, including profiling interfaces.
• Added support for Fortran complex reductions API
• Updated SHMEM_DEBUG output to include detailed build information
• Added --enable-completion-polling build option to poll in quiet/fence
  operations rather than waiting. This can improve performance for libfabric
  providers that require software-generated progress.
• Update symmetric heap allocator to dlmalloc v2.8.6
• Update PMI-1 client library from MPICH
• Improved bandwidth efficiency and fixed bug in collect routines
• Fixed several bugs in tree-based collectives when using PE active sets
• Fixed several bugs in recursive-doubling reduction routine when using PE
  active sets and when source and target buffers overlap
• Fixed synchronization bug in memory management routines
