48ec0b2071 Revert out r12974, 12976, and 12991 as George has provided a less intrusive fix

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).

for switching endianness of headers.  Galen is going to add the code to
use the endian stuff...

c70eb43e43 Align eager RDMA buffer so that last byte of the buffer is on the last byte of 
the CPU cache line. Improves zero byte latency a little bit because of L1 cache
miss reduction.

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..

79bcfb096f Add type to frag. Sometimes we need to know that a frag is from short rdma area. 
I used hack for this that doesn't work for mvapi, so changing it to something more sane.

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)

a584c60dbe re-worked flow control logic to take into account the return 
of credits from the peer prior to local completion, so that
we don't overrun the number of send wqes available.
