ade1b58d84 config: add support for setting the wrapper C compiler 
This PR adds a new configure option: --with-wrapper-cc.
This option allows the user to set the compiler that will
be invoked by mpicc, shmemcc, etc. This allows the user
to build Open MPI with one compiler (a C standards compliant
compiler like clang or gcc) and have the wrapper use
another compiler (icc for example). This allows building
Open MPI with the best available compiler while still
supporting compiling Open MPI for a specific compiler
suite.

86f4128e12 Trivial helper script to git clean submodules 
Since we added the use of git submodules recently, this trivial script
has been helpful to me to "git clean" not only the top-level Open MPI
repo, but also all the included submodules, too.

NOTE: this script does the (harsh) "git clean -dfx" command, which
deletes everything that git does not know about.  Use with care!

a3483e4b71 Fix null pointer arithmetic resulting in potential undefined behavior 
NULL pointer arithmetic is undefined behaviour in c.
The payload_ptr can be NULL in the moment when mpool is not initialized.

- 6.5.6 Additive operators
- 6.3.2.3 Pointers
