90fb58de4f When frags are allocated from mpool by free_list the frag structure is also 
allocated from mpool memory (which is registered memory for RDMA transports)
This is not a problem for a small jobs, but for a big number of ranks an
amount of waisted memory is big.

2b6cbd6299 Separate frag lists for RDMA descriptors to two, one for src descriptors 
and another for dst descriptors. This provide partial solution to OB1 protocol
deadlock problem. We can limit number of RDMA descriptors (by setting
btl_openib_free_list_max to something different from -1) and if we will be
lucky to hit this limit before we fail to register more memory the protocol
will not deadlock. When we had only one list for src/dst descriptors we
deadlocked when we reached max limit for the list.

27cea44a9c Fix a number of issues with the ompi_ptr_t: 
* Make sure that the pval always writes to the correct portion of the
    lval.  This only matters on 32 bit big endian machines.
  * On 32 bit machines when assigning to pval, the other 4 bytes of lval
    weren't being written, which could lead to bogus data

We use macros so that there aren't casts all over the code and the pval
assignment can occur to the correct 4 bytes.  Refs trac:587

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).

0344ae4ac5 Fix to allow eager limit and max send size to be any size (within resource limitations). Instead of storing the ompi_free_list_t * in the fragment, we use the frag type enum, this tells us where the frag came from and where it should return.. This could also be done in mvapi but is not a high priority moving forward.. 
Review by Brian, needs to hit the trunk + 1.1 release..

a5a78b10cc Implementation of short message RDMA. Endpoint registers circular buffer and sends its address and rkey to the peer. Peer uses this buffer to eagerly RDMA small message into it. Endpoint polls the buffer for message arrival before checking HP/LP QPs. Set btl_openib_use_eager_rdma to 1 to enable it.

566a050c23 Next step in the project split, mainly source code re-arranging 
- move files out of toplevel include/ and etc/, moving it into the
    sub-projects
  - rather than including config headers with <project>/include, 
    have them as <project>
  - require all headers to be included with a project prefix, with
    the exception of the config headers ({opal,orte,ompi}_config.h
    mpi.h, and mpif.h)
