bc318b35e2 There is room in convertor to copy the packed data. It works just need to add the correct memcopy. It does not manage the short messages but I alreqdy think of a workaround for this (and it might even be better regarding latency).

33955a0ed0 Oops -- when converted from uint to int, -1 (the default value, 
meaning "infinite") is no longer larger than the minimum required

d2ef0d445a Add some basic timing hooks so I can extract a few more detailed performance 
numbers for tuning.

Switch the bookmark_recv to be non-blocking. If this is blocking then for
process counts >= 32 slight process delays were causing cascading performance
delays in the protocol. This lead to checkpoints either taking about 3 sec or
45 sec (or more) for 64 procs due to the cascading delays. With the nonblocking
receive version this is no longer the case we get the speedup we expect for this
part of the protocol.

More tuning to come.

59b22533f2 Enable RDMA for heterogeneous situations. Currently done by overloading 
the ompi_convertor_need_buffers function to only return 0 if the convertor
is homogeneous (which it never does on the trunk, but does to on v1.2, but
that's a different issue).  Only enable the heterogeneous rdma code for
a btl if it supports it (via a flag), as some btls need some work for this
to work properly.  Currently only TCP and OpenIB extensively tested

ccda5c9c74 Modified the MCA_BTL_TCP_CONNECTED case in mca_btl_tcp_endpoint_send_handler() 
to always first check for a NULL frag pointer before trying to send the
fragment.  This avoids an issue in multi-threaded execution in which 
multiple threads working on the same endpoint can result in a thread 
finding itself here with nothing to send.
