Version 3.4

Added

• PAPI support for TALP metrics
• libdlb_mpic.so and libdlb_mpic_*.so are C MPI only libraries
  that may be built using --enable-c-mpi-library at configure time
• Functions to reset, stop, start and report monitoring regions now
  accept the special argument DLB_MPI_REGION for the implicit region
• Function DLB_TALP_QueryPOPNodeMetrics for third-party applications
  to query pop metrics. Requires --talp-external-profiler.
• Named barriers and several API functions to manage them
• Added --lewi-barrier and --lewi-barrier-select to fine-tune
  which barriers activate LeWI.
• Added --lewi-color to select specific key only for LeWI

Changed

• libdlb_mpif.so and libdlb_mpif_*.so are no longer built by default,
  only if --enable-fortran-mpi-library is set at configure time
• Flag --quiet now only suppresses INFO and VERBOSE, added new flag
  --silent to keep the old functionality to suppress all messages
• Refactor DLB_TALP_CollectNodeMetrics to
  DLB_TALP_CollectPOPNodeMetrics and add communication efficiency
• TALP now appends to CSV files if they already exist

Fixed

• Fixed wrong generated code for MPI_Initialized and MPI_Finalized

Deprecated

• --lewi-ompt no longer accepts "mpi" nor "aggressive" as values.
  Automatic LeWI via synchronization calls is now done with
  --lewi-mpi-calls for MPI and --lewi-barrier or
  --lewi-barrier-select for DLB Barriers.
