Revamp OPAL_PROG_CC_C11 macro in order to define macros only once.
Otherwise, macros get redefined during the configure process and
issue a bunch of warning in config.log. That would also cause
Open MPI fail to build if compiled with "-Werror"

this component can only be used in very specific scenarios. However, since some file systems do not support file locking and processes might be distributed over multiple nodes (hence the sm sharedfp component is also inelligible), the component might be selected in some scenarios, even if an application does not intend to use shared file pointers.
Since the fseek_shared function is involved as part of the File_set_view operation, only complain about the inability to perform the seek_shared operation if actual shared file pointer operations are being used. This avoid spurious error values being returned.

this commit revamps the internal operations of the sharedfp components.
Specifically, it is focused around removing the second file_open
operation for shared file pointers. This makes the code more efficient.
Because of that, there is no necessity anymore for the sharedfp_lazy_open
mca parameter.

This function is only used in ompi_spc.c and is hence declared as static.
Remove its prototype from the header file in order to silence compiler warnings who will typically consider ompi_spc_get_count() as a declared but not defined function.

The PMIx support for "instant on" remains experimental, so disable it by default. Provide an MCA param and corresponding command line option to enable it at runtime.

Fix CID 1435996: use the proper % type to render the size.
Also use opal_output(), not fprintf(). For debug builds, abort
without dumping core (dumping core is very unfriendly when running
thousands of automated tests) -- the stderr output is sufficient to
find the coding error. For non-debug builds, truncate the key and
emit a warning that it almost certainly will not work properly.

This commit add support for scalable endpoint to enhance multithreaded
application performance. The BTL will detect the support from ofi
provider and will fallback to normal usage of scalable endpoint is not
supported.
NEW MCA parameters:
- mca_btl_ofi_disable_sep: force the btl to not use scalable endpoint.
- mca_btl_ofi_num_contexts_per_module: number of communication context
to create (should be the same as number of thread).

configure: add checks for `__thread` on top of current check for `_Thread_local` and define OPAL_HAVE_THREAD_LOCAL if the compiler support TLS.
Added `opal_thread_local` keyword to unify the definition.

This code is the implementation of Software-base Performance Counters as described in the paper 'Using Software-Base Performance Counters to Expose Low-Level Open MPI Performance Information' in EuroMPI/USA '17 (http://icl.cs.utk.edu/news_pub/submissions/software-performance-counters.pdf). More practical usage information can be found here: https://github.com/davideberius/ompi/wiki/How-to-Use-Software-Based-Performance-Counters-(SPCs)-in-Open-MPI.
All software events functions are put in macros that become no-ops when SOFTWARE_EVENTS_ENABLE is not defined. The internal timer units have been changed to cycles to avoid division operations which was a large source of overhead as discussed in the paper. Added a --with-spc configure option to enable SPCs in the Open MPI build. This defines SOFTWARE_EVENTS_ENABLE. Added an MCA parameter, mpi_spc_enable, for turning on specific counters. Added an MCA parameter, mpi_spc_dump_enabled, for turning on and off dumping SPC counters in MPI_Finalize. Added an SPC test and example.

FI_MR_UNSPEC is not supposed to be used beyond ofi version 1.5. This
commit replaces FI_MR_UNSPEC with the new FI_MR_BASIC mode bits
(FI_MR_PROV_KEY | FI_MR_ALLOCATED | FI_MR_VIRT_ADDR).
The btl functionality remains the same.
