c1dcf1c164 The release of memory used by registration lists in rcaches must be delayed until the rcache lock is not held or deadlock
can occur ( fixes trac:2111 ).
Should not deregister memory with the rcache lock held otherwise a deadlock can occur as the lower
level infiniband libraries can free memory ( fixes trac:2110 )

a0b8f061a6 Destroying an rcache vma while the rcache lock is held
as this can result in a low level free of memory which
can require the rcache lock resulting in a deadlock

221fb9dbca ... Delayed due to notifier commits earlier this day ...
- Delete unnecessary header files using
   contrib/check_unnecessary_headers.sh after applying
   patches, that include headers, being "lost" due to
   inclusion in one of the now deleted headers...

   In total 817 files are touched.
   In ompi/mpi/c/ header files are moved up into the actual c-file,
   where necessary (these are the only additional #include),
   otherwise it is only deletions of #include (apart from the above
   additions required due to notifier...)

 - To get different MCAs (OpenIB, TM, ALPS), an earlier version was
   successfully compiled (yesterday) on:
   Linux locally using intel-11, gcc-4.3.2 and gcc-SVN + warnings enabled
   Smoky cluster (x86-64 running Linux) using PGI-8.0.2 + warnings enabled
   Lens cluster (x86-64 running Linux) using Pathscale-3.2 + warnings enabled

9825e087b8 - In rb/rcache_rb.c, the reg->flags should only be operated under the
lock -- therefore move the OPAL_THREAD_UNLOCK after
   the if-OMPI_ERR_TEMP_OUT_OF_RESOURCE block.

 - As mca_rcache_rb_mru_delete is the only setter of rc, move the
   error-check right after mca_rcache_rb_mru_delete.

 - Removed a few nitty ompi/info/info.h and orte/util/show_help.h

8bfcfa464a Don't call free(), or library functions that may call free() inside (such as
ibv_dereg_mr() for instance) from ptmalloc callback. Call to free() from the
callback causes deadlock. Notice what should be unregistered inside the callback
and do actual cleanup at the next call to mpool->register().

906e8bf1d1 Replace the ompi_pointer_array with opal_pointer_array. The next step
(sometimes after the merge with the ORTE branch), the opal_pointer_array
will became the only pointer_array implementation (the orte_pointer_array
will be removed).

190e7a27cd Merge with gleb-mpool branch. All RDMA components use same mpool now (rdma).
udapl/openib/vapi/gm mpools a deprecated. rdma mpool has parameter that allows
to limit its size mpool_rdma_rcache_size_limit (default is 0 - unlimited).

3bf31fe4a3 Correctly determine the first element on the list. opal_list_get_prev() never
returns NULL, it should be compared with opal_list_get_end() instead.
